This article will introduce you to the main types of ribbed and corrugated pipes used in heating systems. It is difficult to imagine a pipe leading to the battery, somehow otherwise than smooth and straight, is not it? However, we are waiting for surprises.

Slika

Let's start with a short acquaintance with different types of exotic pipes. It is necessary that in the future to avoid confusion. For one's own convenience, there is a split pipe into the category by material from which they are made.

Cast iron

Here we can meet only one representative of the family. Ribbed heating pipes are massive pieces of hollow inside the cast iron, which to increase the heat exchange area of \u200b\u200ba misty echry. They are equipped with flanges for the convenience of mounting and, as a rule, are collected in registers of different complexity and size.

Curious: these pipes are applied not only as heating devices, but also as heat exchangers, taking over the stove groove heat.

Black Steel

Convector can be called a ribbed pipe Pretty conditionally - fins are not manufactured at the same time with it. The transverse plates are pressed on the finished pipe to increase the heat transfer. The heating device can be closed with a decorative screen; From above, a adjustable flap can be located to increase or decrease the heat transfer.

Stainless steel

Stainless corrugated pipe for heating - the material that emerged relatively recently. A small wall thickness provides flexibility, and stainless steel strength is a large range of operating temperatures and pressures.

As a sample, we give the parameters with which, according to the manufacturer's assurances, Korean corrugated pipes for heating Kofulso can work:

• Working pressure - 15 atmospheres.
• The maximum allowable pressure is 50 atmospheres.
• Destruction pressure is 210 atmospheres.
• Operating temperature - from -50 to 110s.
• The minimum bend radius is equal to the diameter of the pipe.

Plastic

A flexible corrugated plastic tube for heating - it would seem nonsense. Plastic does not have high mechanical strength; The corrugated pipe is also thin-walled.

Everything is simple: the corrugation for heating pipes is not designed for transporting the coolant, but for the external protection of polymer and metal-polymer pipes when they are laying in a screed or intrauterine installation.

In addition, the heating gofrotrub slightly reduces the non-targeted heat loss.

Attention: do not share - it will not replace the insulation. If you need to reduce heat losses to a minimum - it is worth protecting the pipes of polyurethane foam shell or at least foamed polyethylene.

Corrugated stainless steel: Method of installation, dignity and disadvantages

If all other materials are familiar to us for a long time, then on a corrugated stainless trumper it is worth stopping your attention due to the relative novelty of the material.

Installation

How to mount the heating system with your own hands?

In the design plan, the system has no features and nothing, in principle, does not differ from the metal-polymer with compression fittings. But the pipes are connected in another way. For them, fittings are used without fitting - the pipe is simply crimped outside the gasket from the high-temperature silicone.

The compound assembly instruction is extremely simple:

• Cut the pipe at the place. It is better to use a special cutter. The price of this adaptation is 700-900 rubles, which is not very much against the background of the total amount of the installation costs.
• Insert her end in the fitting.
• Tighten the nut on the fitting with a gas or adjustable key. The gasket is tightly adamped the pipe, making the compound hermetic; Corrugation will provide him with strength. Even a very strong person will not be able to snatch the seeding section of the fitting.

Dignity

They are very convincing.

• The strength and stability of the material to the pressure jumps allows it to be used in central heating systems in conjunction with bimetallic radiators. The eyeliner in this case will not become a weak link.
• Stainless steel is chemically stable and does not forms electroplating steam with aluminum or copper. If someone from the neighbors in general, with you the heating circuit used copper pipes or put aluminum radiators - no negative consequences for you, nor for them it will have.
• Easy installation corrugated stainless heating tube exceeds even notorious metalplastic with compression fittings. The tools are needed the simplest - a pair of adjustable or gas keys and the cutter, without which in principle you can do. The assembly of one connection takes no more than a minute.
• The material has a practically unlimited service life. What is especially pleasant - this period is not reduced when the calculated temperature of the coolant is exceeded.

Useful: The limitation of 110s is quite conditionally and is associated with the heat resistance of sealing pads, as well as with thermal expansion of the pipe and fitting. The temperature at which the stainless steel is noticeably loses its strength, starts about 800 degrees.

Some heating schemes provide for configuration areas of the highway. To actually make them with the help of steel or plastic pipes problematic, and most often it is impossible. An alternative is a stainless steel for heating: corrugation, corrugation, corrugated pipe. What is its advantages, and what operational properties should be considered before installing?

Features of corrugations of stainless steel for heating

It should be immediately noted that not every corrugation stainless steel for heating is able to withstand the maximum allowable pressure in the system. This is due to its feature of its design. For the manufacture, the steel sheet of the SUS304 brand is used. After forming with a special welding mode, a pipe is formed. In the future, it is subjected to additional burning, which gives it the desired degree of reliability, mechanical strength, elasticity.

The main advantage that the corrugation pipe should have a stainless steel pipe for heating - the ability to bend to the minimum radius value. It can be 1-1.5 diameter of the product. Also, when choosing, you need to consider such parameters:

• High-quality corrugation Pipe stainless steel for heating must withstand the average pressure value up to 15 atm., Maximum - up to 50 atm;
• Temperature regime - from -50 to 110 ° C;
• The degree of extension is small - up to 2-3% of the total length;
• The presence of connecting components on the ends.

The latter is relevant, if the length of the section of the line of the highway is exactly known, where the pipe will be installed. If this parameter is not accurate - the corrugated stainless steel is suitable for heating in the bays. Their maximum length is 50 m.

A significant disadvantage of corrugated stainless steel for heating is its cost. Therefore, it is not recommended to make the entire system of it - it is enough to install in complex areas of the system.

Application of corrugated pipe

The main criterion for the choice of corrugations from stainless steel for heating is its quality and properties of the source material of the manufacture. No external signs of deformation, chances or traces of corrosion are not allowed. But more difficult is to test the quality of welding - the durability of operation depends on it. On average, when complying with the rules of installation, the corrugated pipe made of stainless steel for heating can serve until 20 years.

• With a number length. Fittings should be in full configuration;
• With arbitrary length. You need to check the quality of the cut. The edges of the pipe cannot be damaged.

Each stainless steel corrugation for heating has a definite diameter. It has a standard size so that there is no additional hydraulic resistance on a specific portion of the highway. To calculate the volume of coolant, which can accommodate a pipe from a stainless steel for heating in 1 mp You can use data from the table.

The scope of the corrugation pipe of the stainless steel pipe for heating is diverse. In addition to complex areas of the highway, it can be installed in other elements of heating.

During the installation, it is not necessary to stretch the pipe to the maximum length. This may cause its premature destruction due to excessive surface load.

Warm floors from stainless steel

The main property of stainless steel is a high level of corrosion resistance. Given the flexibility, large temperature and maximum pressure indicators most often a corrugated pipe from a stainless steel for heating is used to organize a warm floor.

The advantage of such a scheme is a high thermal conductivity of the pipe. It can evenly warm the concrete surface of 10 cm. Screeds. For installation, it is best to use special mats with guide notches.

Basic installation rules:

• The distance between the turns, at which maximum efficiency is achieved - 20 cm;
• It is not allowed to twist the corrugated corrugation of a stainless steel for heating in certain sections. Thus, a surface tension occurs, which may damage;
• Installation is not recommended using additional polymer casing. They will not increase strength, but will lead to a decrease in heat transfer.

The cutting of a pipe from a stainless steel for heating can be done using "Bulgarian". To do this, you need to fix the product with clamps or plumbing vice.

For the corrugation of stainless steel for heating, special fittings should be purchased. Their design is designed for mounting on an uneven outer surface.

Source to heating devices corrugated pipe

Due to its flexibility of the pipe-corrugation of stainless steel for heating can also be used to connect radiators. With it, you can minimize the complexity of installation and reduce the length of the entire highway.

One of the disadvantages of such a connection is the complexity of the manufacture of the bypass node. Installation of shut-off valves will be problematic.

Unlike a warm floor system, the corrugated stainless steel before installation in heating should be thoroughly insulated. Large thermal losses will reduce the efficiency of work and lead to uneven distribution of thermal energy throughout the house.

Installation technology is to comply with the following steps:

• With the help of a grinder or special pipe cut, a corrugated stainless steel pipe is cut off for a subsequent installation in heating;
• Installation of a previously selected fitting. To fix with the surface you need to tighten the nut. It is important to control the effort - damage or deformation of the pipe;
• After final installation, the tightness of the node is checked.

To select a high-quality corrugation from a stainless steel for the heating system, it is recommended to purchase products from proven manufacturers. Currently, they are Kofulso, Lavita and EasyFlex. The average cost of their products is from 160 to 270 rubles / mp.

What else to take into account when choosing and installing stainless steel for heating: corrugations, corrugation, corrugated? Thanks to the properties of the material of manufacturing on the inner surface, a lime flare will not be formed. This will significantly increase the time between the mandatory cleaning of the heating system.

Advantages and disadvantages of stainless corrugated pipe for heating

We are all used to the pipes used in heating networks, these are smooth designs. In any case, it was until recently. Although it is necessary to recall the cast iron samples with the fins, which were connected to each other with the help of flanges and rubber gaskets. True, it was conventionally called their pipes, because their main purpose is the heat transfer. Why did we affect this topic? Because there were completely new types of pipes on the market, which turned the idea of \u200b\u200bthem from heads. For example, a stainless corrugated pipe for heating.

It is almost a substitute for a dear copper pipe for heating. After all, the stainless steel in its technical characteristics will not yield. But in the price plan, it is at times cheaper. So it turns out that the appearance of stainless steel corrugations solves the problems associated with the high-cost best heating pipes. We all receive high quality products at reasonable prices.

By the way, here is the technical characteristics of a corrugated pipe from a stainless steel for heating from the famous Korean manufacturer of Kofulso:

• Working pressure - 15 atm.
• Permissible pressure - 50 atm.
• Pressure in which the pipe begins to collapse - 210 atm.
• The temperature of the coolant + 110c.
• Diameter from 15 to 32 mm.
• Wall thickness from 0.25 to 0.3 mm.

These are just excellent indicators, especially pressure. These pipes can be used in urban apartments with a centralized heating system.

Standard delivery

Attention! There is one unique indicator of this type of pipe - the radius of its bend is equal to its diameter. If you recall the plastic tube of stitched polyethylene, which is considered the flexible, so its bending radius is six diameters.

Why is this type of pipes have such high flexibility? It's all about the thickness of the material from which it is manufactured. It is thin, and the stainless steel itself is very durable. Therefore, it turns out that when it is bending it does not break. Although the strength of the material affects the withstanding loads, that is, the temperature and pressure of the coolant.

Advantages and disadvantages

Dignity

• Made such pipes from high-alloy steel. The SUS (AISI) 304 brand is most often used, which is used in the food industry.
• These pipes do not corrosive, they do not form colonies of mold and fungi. And if you compare them with steel pipes for heating, then it is just the sky and earth.
• Easy installation work. To do this, you will need a set of wrenches and certain fittings.
• The product from a stainless steel can withstand several defrost cycles.
• Since it is a durable metal, then it is not for the rodents.
• Small share, and this is the convenience of transportation and laying.
• High thermal return of material.

Corrugated pipe in heating system

By the way, I would like to return in the temperature withstanding. We mentioned about the Korean manufacturer, so it has one of the lowest indicators, because European manufacturers guarantee + 150 ° С load. By the way, even at such a temperature with a pipe, nothing happens, and this limitation is connected only with sealing rings, which are used when connecting pipes. They are calculated on such temperature loads.

Attention! For information - on the market you can find sealing rings that hold the temperature of + 300 ° C.

disadvantages

High price product.

High fittings. By the way, manufacturers of pipes for heating from stainless steel are not engaged in the release of fittings.

Stainless corrugation register

Process of production

• Steel blank is rolled into the tape.
• Then the pipe itself is formed. Welding tape is made by the latest technology called TIG.
• The next stage is corrugated.
• And at the end, the finished product is thermal processing. By the way, it is at this stage that the pipe acquires its special flexibility.

Attention! Do not think that this flexible tube can be bend, how much you want. It is warful that after 10-15 bends (it all depends on the manufacturer) the product will simply break. So be careful.

Stages of the assembly process

The assembly of the metal pipe for heating from stainless steel is made using brass fittings. From the bottom in the photo is shown in which order must be connected part of the connecting elements.

Sequence of assembly

Let's go through numbers:

The assembly of the node occurs according to the following scheme. Nut and two rings are put on the pipe, gasket fitting. Then the pipe is inserted into the fitting until it stops and is clamped with a cape nut. At the same time, the locking ring clings to the corrugation and does not allow it to jump out. By the way, it is the stopper that is responsible for the safety of the compound during hydraulic impact. Silicone gasket provides a junction tightness.

Application area

The fact that these models are used in housing construction today does not cause any doubts. But their small diameter and length create some inconvenience, so they do not apply them in large boilers. But for a private house, this is a great solution. Especially when it comes to the heating system "Warm floor". This is where corrugated stainless steel pipes will show all their advantages. Do not forget that these are products with very high heat transfer.

In DHW systems, these pipes are used too. Someone establishes them on water supply networks, in the gas supply, air conditioning and fire extinguishing system. If there is money, why not take advantage of the best pipes to date with a huge period of service? All investments for such a term will be taken more than.

Warm corrugated pipe floor

But this type of pipes is increasingly appearing on various industries. They replace plastic counterparts, because the stainless steel is perfectly withstanding various aggressive fluids without changing its sizes (especially diameter). Therefore, in the chemical and food industry, in plants for the production of drugs, corrugated pipes made of stainless steel today are very popular.

Stainless corrugated pipe for heating - New in the field of organization of heating networks

New type of pipes - a stainless corrugated pipe for heating, which has excellent technical characteristics with one disadvantage - high cost

Stainless steel is a material with maximum utilitarian and excellent performance: it is strong, not subject to corrosion, can be used at any temperatures, has a long service life.

It is these advantages that have provided heating pipes from the stainless steel of their current popularity. Today we will talk about the advantages and disadvantages of stainless pipelines, consider their installation, as well as analyze the current market prices.

Product Features

Not fond of unnecessarily colorful descriptions, immediately consider everything "for" and "against" concerning stainless pipes for heating.

Benefits:

• Stainless steel pipes for heating have a long service life. This is explained by the fact that stainless steel, as a material, is absolutely not afraid of corrosion: not from the effects of liquid, nor from the acid medium;
• Stainless steel pipes during operation are not exposed to linear expansion. For this reason, on their basis, the installation of intrauterine heating systems from steel pipes can be carried out;
• A stainless corrugation for heating has sufficient elasticity. Corrugated stainless steel allows you to use it in gaskets of heating highways, where there is a large number of bends.
• Stainless steel heating pipes have high hardness and rigidity, as a result of which they carry the hydroedar to 15 atmospheres for a short time, and they are not afraid of mechanical effects from the outside;
• Such pipes have a wide range of operating temperatures: they are not afraid of freezing, and can transport the medium whose temperature exceeds 400 degrees;
• Installation of heating registers from steel pipes is characterized by high efficiency, since the stainless steel has a good heat transfer coefficient.
• Installation of a stainless steel heating system is extremely simple: for this it is not necessary to use special fittings or equipment, all connections are performed using conventional fittings.

The disadvantages of this type of pipes are much smaller than advantages:

• It is worth a recognition that the corrugated pipe-stainless steel for heating has a fairly specific appearance, which is not suitable for the design is not every room;
• Price: stainless steel highly expensive material, so that such heating pipes and fittings will cost you completely at all.

Regarding the last point - we note that the high density of the stainless steel allows manufacturers to produce high-quality, strong pipes and fittings that have, with a relatively small thickness, so that their final cost is reduced.

Specifications

GOST on heating pipes 3262-75 causes sufficiently strict requirements for stainless steel products. According to him, high-quality stainless pipes and heating fittings must comply with the following technical specifications:

• Normal working pressure - 15 atmospheres;
• Maximum allowable pressure in the pipeline - 50 atmospheres;
• Pressure, followed by deformation and destruction (gap) - 200 atmospheres;
• The lowest temperature of the work environment: - 50 degrees;
• The minimum acceptable bending radius should be equal to the product diameter.

The technology of manufacturing corrugated stainless pipes is fully automated, which contributes to the highest accuracy of each production phase. Consider the stages of the manufacturer Read more:

• First of all, the sheet of stainless steel is pre-processing, after which it is fed to the forming conveyor, where it is given a cylindrical form.
• Next, there is a connection of the joints of the cylinder by means of welding, which is performed in a special gas environment.
• At this stage, the formation of corrugations (ribbed coating) - for this, the billet is rolled through rollers of different diameters.
• The pipe, which already resembles the final product, passes a special thermal processing, which gives it the necessary indicators of elasticity.
• The last step is to cut the segment on parts of the desired size (mostly 50-thimeter pieces), which are wounded in the bay.

Nuances of Montaja

It is worth remembering that one of the main advantages with which the steel corrugated pipe for heating is flexibility, while at the same time it is its ahilles fifth.

Do not stand the design when installing multiple bends in one place. Also, if in the house where the heating system from a stainless steel will be installed, there are children, it is worth thinking about how to reduce their contact with pipes to a minimum.

If children will use a flexible tube and its fittings as a support, or a crossbar, then gradually accumulated "fatigue" of the material will exceed the permissible rate, and the design is deformed.

Welding steel pipelines of heating from a stainless steel is not required - basically such structures are connected using special fittings.

Installation of the heating system from steel pipes is performed as follows:

1. The corrugated stainless trumpet joins the device, which supplies hot water to the heating system, by means of universal polymer, or rubber seals that are included.
2. Further, on the site of the first connecting unit, the pipe is trimmed with a special roller cargo (if any, it is possible to use a conventional grinder), after which all sowers are thoroughly wondering from the cropped end.
3. At the end of the segments that will be connected (the diameters of steel heating pipes must be identical, of course), fittings are put on, which are screwed into each other. Check that the cape nut is properly tightened.
4. The pipeline is fixed in the desired position on the wall using special brackets.
5. Upon completion of the installation, apply water to the system, and check the tightness of the connections.

Montage Nuances (video)

When buying stainless pipes, you should carefully look at such details:

• The external coating of the product should be as smooth, it should not be present chips, cracks, or dents;
• Thoroughly inspect the entire length of the segment - there should be no cracks and dots, which are formed due to excessive bending, because it is precisely in such places, with time, deformation occurs, and, as a result, the depressurization of the system;
• Each of the connecting fittings should be equipped with a special sealing gasket if it is missing - the fitting can be thrown into the trash tank.

After analyzing the offer of manufacturers in the plumbing market, it can be concluded that the price of stainless heating products depends, primarily on their diameter, as well as from the "brand" of their company producing their firm.

We will not advertise good or bad manufacturers, and simply recommend to pay attention only to products that correspond to GOST of the Russian Federation 3262-75 (as evidenced by the availability of an appropriate license), which is a sufficient guarantee of quality.

There is a large range of stainless pipes on the market, which will satisfy all segments of the population with different financial capabilities.

Another question is how much the service life of steel stainless heating pipes that are sold cheaper than plastic. Usually, products of this type without problems serve at least 20-25 years, subject to the rules of operation and the absence of mechanical impact.

Trying to find the minimum cost of steel products for heating, you play the lottery.

Cheap products can serve for many years, and they can begin to deliver trouble at the very beginning of operation.

So it is better to immediately buy good stainless steel pipes, even if choosing and not the cheapest option.

Well, finally, we mention concrete numbers.

The price of steel products for heating from corrugated aluminum in the minimum diameter (15 mm) begins with 2 dollars per meter, and increases according to its magnification.

You can buy steel pipes for heating in a diameter of 50 mm (2 inches) at a price of $ 20 per stranded meter.

Steel galvanized heating pipes are presented on the market in the price range from 1.5 dollars for the traffic point meter of the product 15 mm in diameter, up to 6 dollars per meter in a diameter of 50 mm.

Flexible, hot, shiny: stainless steel pipes for heating

In this article, I want to introduce a reader with a relatively new material - a corrugated stainless pipe. We will study its key features, get acquainted with several samples from different manufacturers, compare corrugated stainless steel with competing solutions and exploring its installation rules.

What it is

A stainless corrugated pipe for heating is thin (with a thickness of the walls of 0.3 mm) stainless steel corrugation, obtained by folding the infinite tape. Here is the typical composition of the metal:

In some varieties of steels used in the production of corrugated pipe, up to 30% of molybdenum. It increases the viscosity and strength of the metal.

For installation of pipes are used compression fittings with high-temperature silicone seals. When tightening the cape nut, the silicone ring crimps the corrugated pipe, excluding spontaneous domain of the connection.

For installation in the cold water supply system, the pipe is supplied with an external polyethylene sheath. Polyethylene has a relatively low thermal conductivity and helps to get rid of condensate. The same pipes can be used on heating: the shell prevents possible burns at high heat carrier temperature(for example, when installing the radiator in the children's room).

Below are the characteristics of steel heating pipes, the needs of government parameters, and more methods for their compound. Additionally, you will be able to get acquainted with the types of fittings and ways to install it on the contour.

Metal in work: Parties as weak and strong

Stainless steel pipe

Steel is deservedly considered the highest quality material for equipping heating systems. Until recently, the emergence of plastic analogues, steel pipe for heating was used very often. Strong sides:

You can press on the contour of your hand and even become on it, and it will hold it very easily. Hydrowood Similar products hold better than any other;

• excellent resistance to heating process.

In plastic contours, the maximum possible level of heating the heat carrier is 95 degrees, the risk of depressurization appears on. Metal melts at a temperature of 1500 degrees, there is no such in heating systems. The largest temperature in steam heating is not more than 200 degrees, which is negligible if compared with the strength reserve of stainless pipes for heating;

• low temperature expansion.

Heat supply from steel pipes in a personal house is allowed to do secretly, stirring them into the wall without additional compensating linear and volumetric temperature expansion of materials.

Most plumbers are afraid of steel heating pipes, as they simply do not know how to work with them. Good masters of the "old school" are ever less often.

For open-type heating systems are those in which the heat carrier is moving independently without the help of electrical pumps, products with a large diameter are used. Plastic for this does not apply. At the same time, in open contours, the main enemy became air to which the heat carrier in excess is saturated in the expansion tank.

In addition to the circuit of the contour, the metal is used to equip the chimensions. A pipe for a heating boiler from stainless steel, which displays the products of sunbathing outside, should be heat insulated. To make it use heat-resistant materials.

Corrosion Pipe Profile

How the air destroys the metal:

• the water is saturated with air in the expansion tank and involves it into circulation;
• when heating the heat carrier, air bubbles begin to actively separate from water molecules;
• metal with mutual action with water and air begins to oxidize, corrosion occurs. If there is no air - corrosion does not appear.

For closed-type systems (hermetic), the problem of corrosion is not so acute, even in a sealed circuit also penetrates the air simultaneously with the heat carrier. To reduce this process, air separators that stirring the stream are put at the entrance, emphasize the oxygen bubbles from it and output it in the automatic mode. The next Beach of Metal Systems is the difficulty of installation, which is associated with both heavy construction, and with the necessary professional abilities of the installer.

The working period of steel heating tubes from ferrous metal is about thirty years. Stainless pipes for heating are actually eternal.

Characteristics according to GOST.

Production is performed by 2 ways:

Steel Seamless Pattern

If you proceed from this, underline welded and pipes from seamless rolled stainless steel for heating. The largest diameter of welded products is much higher than that of seamless and can reach 2.5 meters. They are welded by a furnace or electric welding. The latter will forgive and in the gas chamber.

Gosstandart No. 3262-75 It was determined that the steel pipes of the home heating system should be produced in size from four to twelve meters. In addition to the measured, they can be manufactured by the specialized order of non-meter long, parts from one and a half to four meters. The cross section of the inner products may vary from 6 to one hundred fifty millimeters, and the outer diameter is based on this from 102 to 165 millimeters. Depending on the wall thickness, the steel pipes of the heating system are divided into:

This characteristic also depends on the mass of products, which is calculated in kilograms per 1 meter of the product. The calculation is carried out with taking into account the density of the material, which is 7.85 g / cm3. For finished products, the standard resolves maximum deviation:

• the outer diameter of steel heating pipes is not greater than 0.4 mm for the products with an internal cross section of up to 4 cm. For products with a relative passage, more than 4 cm deviations are marked as a percentage and is 0.8;
• mass - no more than eight percent;
• geometry - on one meter, the curvature should be in the aven a half percent for products for products, the diameter inside which is up to 2 cm. And for pipes, the symbolic passage of which is more than 2 cm, the deviation is no more than 2 percent.

Galvanized profile pipes for heating in accordance with GOST 3262-75 by 3% harder than ordinary. The zinc coating should be the same, and its thickness is at least 30 microns. At the ends and threads, its presence is optional.

The ends of products that can be smooth, with thread, or with a coupling are also distinguished. Thread is long and short. It can be applied to one or two sides of the product. In addition, at the request of the customer may be chamded. At the same time on the ends, the metal should not be lazy. On the surface from the outside, the presence of insignificant scratches and other disadvantages that are not at all are displayed on the product characteristics.

Much attention is paid to protective coating from zinc, if such is calculated in the manufacturing process. A stainless steel pipe protection layer for heating is obliged to be smooth, without bubbles and peeling. The thread can be cut exclusively after a layer of protection is applied.

At the end step, zinc steel pipes of the heating system are tested by pressure. For this, hydraulic checks are underway, according to the results of which ordinary pipes should keep the load at least 25 atmospheres, and reinforced - at least 32 atmospheres. At the request of the customer, this indicator may increase to 50 atmospheres.

Accessories, Docking Methods

For pipe connections, two ways are emphasized with each other:

Fittings with carving for pipes made

welding butt jack;

Fittings include fittings for steel heating pipes and flanges. Consider any product separately. Fittings are of different shapes (straight, under an angle of 90 degrees, crossmen and more). The main thing is the way they are connected to the contour:

The mounting compound in the form of a thread is considered to be terminated. Welding fittings based on this, an indefinite type of connection. They do not have a thread, and the heating system of pipes from steel is combined with electrical, or gas welding. Clamping accessories practically does not stand out from substitutes for plastic systems, except for some additional parts, for example, as:

• clamping ring - no need to be confused with the clamping (colangu);
• plastic seal ring.

Construction of clamping fitting

Clamping fittings do not give high quality connections and are used as a short-term measure. Such a joint is very sensitive to loads mechanically and can give to flow. In this case, all the advantages have become simply reduced to no.

Flanges are a compound consisting of 2 rings. They are fastened with bolts among themselves, and they are attached to the contour or threaded or welding. Also there are differences in their surface, it can:

Flanges for steel pipes

be flat;

have a groove or spike;

have a groove for a ring for seal.

This type of compound is considered collapsible and used for products, their diameter is superior to 5 cm.

All about the installation process

Main points of the assembly process:

• the very first thing you need to do is cut the pipes on the desired segments.

To do this, apply a pipe cutter or a saber saw. Trubores divide the product on segments using cutting discs that need to be sometimes changed. For stainless steel there are special disks that are sharpened in a special way, which makes it possible to work with more viscous materials. Using the manual tool is not always possible, for example, when you need to cut off the part of the outline. Thanks to this, a saber saw is applied. It is attached to the circuit, so that a smooth cut came out;

Do not use angular grinding for cutting a part of the already supplied circuit. In addition to sparks, there is a risk of COP or shock, if the water from the system falls on the tool. Use a saber saw.

Fixture compaction in the form of a carving light

There are several types of threads: cone-shaped and cylindrical. To cut the threads need a thread-cutting club, which will probably be manual or electric. To reduce the friction and heating of the metal during operation on the metal surface, oil is supplied. When installing the fastener compounds in the form of threads seal Lyno;

To make it need to be needed pipe bender. Some craftsmen do without him, they simply warm the place of bend of hot and bent the product with their arms. Only in this embodiment, the symbolic passage is almost 100% probability already.

In addition, registers are made of pipes made of metal. The heat supply register from the steel smooth pipe is, as it were, a battery consisting of several parallel pipes, which are interconnected so that the thermal carrier can circulate freely. The heat supply registers from steel pipes are used in premises not for accommodation, in production, in farms, schools and kindergartens, etc. You can also install the crane Maevsky, thanks to it you can burst the emerging air traffic jams.

Fastening steel heating tubes is performed according to the following tips:

• for products with a diameter of up to 2 cm - every 2.5 m;
• for products with a diameter of up to 4 cm - every 3 m;
• more than 4 cm - every 4 m.

As soon as the system is ready for the operational input, it is necessary to check it, which is called crimping. This is the testing of the contour to the fortress and pressure of pressure exceeding the working.

How to apply stainless pipe heating systems?

If you inspect a lot of publications and the rest of the information that concerns the pipes from a stainless steel, first see: the authors describe the properties of these pipes exclusively in excellent degrees, noting only the only minus - their large price. They are actually notable, however, if you correctly apply stainless pipes of the heating system, the benefits of such use (also economic) will pay off your big expenses with an excess.

Greedy pays more

It is necessary to start with what to receive savings is absolutely not to save everywhere where there is an opportunity. Stainless steel pipes are offered with suture and seamless suppliers. Sowing - much cheaper. However, if you, guided exclusively with economic considerations, apply suture (welded) stainless pipes of the heating system - prepare for the fact that in terms of the time of time, let and long, in your heating system will first arise leaks in your heating system.

The system will need to change, welding or stainless steel coaches - a very heavy and large and expensive process. This will happen significantly later than when using ordinary, "black" suture pipes, stainless steel pipes have high anti-corrosion characteristics, but will happen first. Stainless pipes of heating system should be used exclusively seamless.

More about savings, and not only ...

If you are with all the seriousness "saved" and used in the device of heat supply "black" pipes, it can occur so that your financial missions will be invisible for a long time. More precisely, the invisible will be his reason. You will sometimes acquire and change the cranes, valves, connecting elements with a thread from two strands and other shut-off valves, scolding the "dishonest" manufacturers, and the reason is in the very "economy".

The reason is in the "black" pipes. They have a property to oxidize, and the oxidation product - corrosion - scores and displays the shut-off valves. When applied to heating pipes from a stainless steel of a similar one, it cannot be simply noted by definition - stainless steel pipes are never covered with rust ever.

We did not touch here the individual largest topic - the uses for heating the elastic pipes from the stainless steel. The range of their use is quite wide - these are "floating floors", and "warm walls", and strapping boilers, and much is different, which will inevitably lead you to saving funds, although the initial costs can be substantial. But the main positive qualities of stainless steel pipes are a fortress and anticorrosive stability - with some period, first of all give a natural, and not an imaginary financial effect.

Which pipes of the heating system are better: steel, plastic, copper, metal-plastic, stainless steel, characteristics, photos and video

In the current world there are very and very many pipes that are intended for heating, and any of these species are great when it is in its own place. So it is best to immediately figure out where and what pipes the heating system is better.

Types of heating pipes

Types of pipes for heating systems:

• copper;
• stainless steel;
• plastic;
• steel;
• from metalplastic.

It is worth dealing with great attention, which is exactly the most suitable in your case.

Profile pipes

Profile pipes are on guarding heat supply is already far from the first decade. They are reliable, have good performance in operational terms and tested by time. Professional pipes from metal Mila also due to the fact that they have a rather long operational term. For pipes from steel do not matter temperature differences and even very large heating and pressure coefficients in heat supply.

But if it seems to you that this option is considered perfect, do not forget that this is not the most affordable pleasure from all alleged. Moreover, the heating system of the houses made from metal is quite good.

Pipes made of metal are the harder to hide from foreign eyes, and only a used welder should be engaged in the process of installing the heating system. Similarly, the use of such heating pipes is reasonably where the greatest fortress is necessary, some very large diameters are used or it is necessary to free themselves from obsolete iron pipes.

Plastic pipes

Pipes made of heating plastic recommend such advantages as a sufficiently long service life, resistance to wear, low weight, ease when performing a mounting process and good low cost. You can also select among the desired number of designers solutions. However, various plastic pipes have a different composition for which its own installation conditions are needed.

Pipes of plastic and components

Before making the final choice, you should contact a professional consultation, which will recommend which pipes of the system of heating a personal house more convenient to buy.

An interesting property of plastic pipes has become their ability to lengthen or bent at the time of filing the heating system of a very hot heat carrier. It is necessary to take into account if it is supposed to close the plastic pipes into the wall or close the decor components, otherwise the crooked pipeline is able to squeeze even a whole piece of plastering from the wall.

Moreover, pipes made of plastic for heating systems cannot be involved, so for those places where the bending is required, you will have to purchase a corner. And if there will be many similar elements, you can not remember the aesthetic component. Plastic pipes are also incredibly complex during the installation process, have impressive dimensions. To install plastic pipes, experience is required. If the installer exceeds the pipe, then when the passage diameter is installed, or it is implanibly narrowed, or the passage will completely block.

According to the own essence of pipes from metal plastic for heating - this aluminum products with walls with a thickness of no more than one tenth millimeter, inside and outside covered with a specialized polyethylene film. Pipes from metalplastic have very high-quality connections among themselves and are capable of holding a given form for a long time, even if you have to bend them.

If you walk on the comparative properties, then, in contrast to other pipes, the metroplastic has only one big drawback - the fittings needed from the metal is very costly. Pipes and fittings to them worth buying exclusively in special stores. Despite the expensive price, you will get conviction as products. At the same time, the proposal of inexpensive pipes of a similar type faster means that you are trying to realize fake.

Pipes from media

During reflection about the choice of heating pipes, thermal networks do not need to neglect information about copper pipes. The copper pipe is well appreciated by professionals for large areas of use, because copper pipes can be used not only for mounting heating systems, but also for gas highways, water supply, since the large content of chlorine does not have a destructive effect on the metal.

Copper pipeline

Plastic pipes can literally die, having met with some kind of chemistry. However, copper pipes in heat supply on the contrary in many cases will increase their own fortress, as a result of formation on the metal surface of a small laid. The working period of pipes from copper can be 50, and even 100 years.

Not devoid of copper pipe and certain minuses. For example, they are very difficult to cook, so it should be done by a professional with experience equipped with specialized equipment. The compounds are locked up by specialized press connectors, in the middle of which there is a rubber ring. Over time, it is dry, and depressurization occurs.

Moreover, copper pipes for heating systems are too expensive and will not be combined with products from some other materials. They are terrible electrochemical corrosion.

Stainless steel pipes

The heating system mounted from stainless steel pipes is considered to be actually the standard of reliability and strength. Pipes made of stainless steel for the heating system are able to move without loss of fairly high working pressure, they have a wonderful and today's design, they do not change the composition of the heat carrier and are not afraid of any corrosion.

Practical stainless steel heat supply

Stainless pipes are easy to assemble both from the outside of the pipe and in the middle. But in order to please yourself with such acquisition, you will need to post a very large amount.

In fact, decide which pipes the heating system is better to choose, it is to you. However, it would be nice to approve their own desires and to draw their own questions to a professional who will help not make a mistake with the choice.

Galvanized heating pipes, flexible eyeliner and corrugated stainless steel pipes

Stepping with the times, all the much improved products are being developed, also, and a variety of pipe options, for example, flexible stainless galvanized heating pipes have arisen. There is a wide selection of materials from which such pipes are made, we will consider in detail.

Galvanized heating pipes

1. Cast iron pipes. These can be attributed to the ribbed galvanized pipes of the heating system, they are of themselves heavy slices of hollow cast iron. They are used not only as radiators, but also as heat exchangers that take away from stoves, too much heat.
2. Black steel. In this case, the transverse plates are pressed on the already finished pipe, in order to make more heat return.
3. Stainless steel. These include corrugated stainless steel pipes for heating. Thanks to the small thickness of the walls, the pipe flexibility is ensured, and since stainless steel is very strong, then there are a wide range of operating temperatures, and pressures.
4. Plastic. Since plastic does not have great strength to mechanical actions, it is used exclusively for the external protection of polymer and metal-polymer pipes.

Installation of pipes from corrugated stainless steel

This is a pretty new material for pipes, thanks to this, to make them installation for the majority. From the design of the design, there is nothing original here, but from the side of the pipe connections there are certain subtleties. For their compounds, fittings are used without fitting, the corrugation for heating is crimped from the outer side by the gasket made of high-temperature silicone.

Corrugated stainless steel pipes for heating

• Fortress and resistance to pressure jumps. This makes it possible to use it in centralized heating systems simultaneously with Bimetal radiators.
• Chemical staining stainless steel.
• Ease of installation. Tools are needed very simple, and on the assembly of one connection is not more than a minute.
• A high service period that does not exceed less when the carrier temperature is exceeded.
• Such pipes are not afraid of defrost, as they are very resistant to frost, due to this can be applied as the pipes of the heating system, as well as for the "floor heated floor" system.
• Pipe stainless steel corrugated for heating is not served corrosion, and sedimentary sediments do not appear in it.
• Its texture is plastic, and it also contains an unusual design.
• Maybe without fears, it is used in the raw and premises of the basements.

Heated floor with stainless steel corrugation pipe

If we compare with positive qualities and good quality stainless steel, minuses are quite small:

• Appearance.
• Price. Even in our time, similar pipes for heating from stainless steel are quite expensive.
• If stainless steel will be regularly subject to deformation, it will eventually come to unsuitability. Thanks to this, such pipes do not need to be placed where there is a very high probability of damage from the mechanical factors of the pipe or the effect of the aggressive medium.

The pipe should not be flexing and blending in one place, it is also undesirable to twist it. The flexible stainless pipes of the heating system can still be saved in a dry room, it is necessary only that they are protected from a variety of damage from mechanical factors and have not been contacted with different materials from the metal.

Appearing in our market, a pipe made of stainless steel for heating quickly found his own niche and became very popular thanks to his own advantages, and even more so - durability. But taking into account not the smallest price, not anyone who wants to be able to establish a similar pleasure as a flexible eyeliner for heating. Although, if we take into account their strength and long use, in the embodiment of all operational rules, and even taking into account technical properties, such a value is not considered high, but is quite optimal.
