Any light and dark petroleum products can be stored in RVS tanks, oil-containing drains, liquid mineral fertilizers With a density of not more than 1015 kg / m 3.

TD SARRZ delivers vertical tanks of the following structures to place of operation:

• rVS tanks without pontoon
• rVSP tanks with pontoon
• floating roof RVSPK tanks

All supplied vertical tanks are made by:

• GOST 31385-2008 "Reservoirs vertical cylindrical steel for oil and petroleum products. General technical conditions"
• Hundred 0048-2005 "Reservoirs vertical cylindrical steel for storage of liquid products. Design rules"
• STO-SA-03-002-2009 "Rules of design, manufacture and installation of vertical cylindrical steel tanks for oil and petroleum products"

Design of vertical tanks for petroleum products

Vertical RVS tanks have a cylindrical wall and flat or conical bottoms with a slope from / to the center.

To protect the stored product from contamination from entering it, as well as to prevent the insertion of flammable evaporation into the air, the roof or pontoon is installed on top of the RVS wall. Roofs can be stationary (frame / frameless, spherical / conical) or floating depending on the properties of petroleum products, the diameter of the tank and the requirements of the customer. For example, frameless conical roofs are used on tanks with a diameter with a diameter of not more than 12.5 m, frameless spherical - up to 25 m, frame conical - on RVS with a diameter of 10-25 m, spherical frame - more than 25 m.

Floating roofs apply to maximum protection ambient From harmful evaporation and to protect the stored product itself. Depending on the climatic conditions operation, namely from snow loadsFloating roof may have a one-day or twin-designed design.

At the request of the customer, vertical tanks for oil products with a stationary roof can be completed pontions - Floating construction, similar to floating roof. Ponteon design should ensure its buoyancy both in the process of draining-liquid operations, so in the case of force majeure. For the safe operation of the RVSP should be equipped with ventilation system.

The wall thickness and bottoms depends on the diameter and the volume of the tank itself. So, the wall must be 5 mm for diameter 16 m, 6 mm - for 16-25 m, 8 mm - for 25-40 m, 10 mm - 40-65 m, 12 mm - more than 65 m. The bottom must be at least 4 mm for RVS with a volume of up to 1000 m 3 and 6 mm for RVS volume of more than 2000 m 3.

Steel brand for the manufacture of RVS is selected and calculated at the design stage and depends on the degree of aggressiveness of petroleum products, the temperature of the stored product and climatic execution, as well as the properties of the steel (yield strength and shock viscosity). Roofs and pontoons can also be made of aluminum.

Characteristics of the RVS-100

The main structural elements of the reservoir RVS-100 m 3

• wall, including knockboxes of nozzles and hatches,
• bottom,
• stationary roof
• playgrounds and roof fences, stairs,
• technological hatches and nozzles.

Wall

The minimum thickness of the wall sheets for RVS-100 is 4 mm. The minimum recommended dimensions of the main sheets of the wall are 1.5 × 6.0 m.

When designing, it is necessary to take into account the stability of the tank body for an individual combination of loads, including seismic impact, the weight of the stored product, the weight of structures and thermal insulation, excessive pressure and weight of snow cover.

To ensure the strength and stability of tanks during operation, as well as to obtain the required geometric shape In the process of mounting on the walls of the tanks, rigid rings are installed.

Bottom

The bottom of the vertical steel tanks with a volume of 100 m 3 can be designed with flat or conical with a slope from the center to the periphery (recommended slope 1: 100). At the request of the customer, it is possible to make bottoms with a bias to the center of the tank.

The bottoms of the RVS-100 are preferably made in the form of a roll-up cloth from the sheets of one thickness without ringwalls (the presence of a sheet of different thicknesses in the roll-in tunnel is not allowed).

The nominal thickness of the sheets of the central part of the bottom or bottom without the glands less than the absorption of corrosion should be 4 mm.

Stationary roofs

Vertical tanks of 100 m 3 3 are usually designed with two types of stationary roofs:

• frameless conic roof, load bearing capacity which is provided by a conical shell of flooring;
• frameless spherical roofcarrying the ability of which is provided with rolled elements of the flooring forming the surface of the spherical shell;

Frameless roofs can be made of carbon or of stainless steel. The use of stationary roofs of aluminum alloys is allowed.

The nominal roof shell thickness is determined by the calculations on strength and stability and should be at least 4 mm.

Pipes and hatches

Pipes in the wall are designed to attach outdoor and internal pipelines, Instrumentation and other devices.

For the manufacture of nozzles and hatches, seamless or straight pipes and shells made from rolled sheets are used. Holes in the wall for installing nozzles and hatches must be strengthened around the perimeter with sheet lining.

In the basic configuration of the RVS-100, there are two nozzles of reception and distribution of the product, which are located in close proximity to the bottom in the vertical bending area of \u200b\u200bthe walls. Pipes with a nominal diameter of 50, 80, 100, 150 or 200 mm are recommended.

Luke Lases in the walls of the RVS-100 are designed to penetrate the inside of the tank during installation or for repair work. The standard reservoir must be equipped with no less than two hatches, providing access to its bottom. The tanks with a pontoon besides this should also have a hatch-laz at an altitude that provides a pontoon exit in its repair position. It is recommended to use round hatches diameter 600 and 800 mm and oval hatches with dimensions of 600 × 900 mm.

The amount, sizes and types of nozzles in the roof of the RVS-100 depends on the purpose of the tank and are determined by the customer. For inspection indoor space Reservoir, its ventilation during internal workAs well as for various mounting purposes, the tank must be equipped with no less than two hatches in the roof. The hatches are recommended with a nominal diameter of 500,600, 800 and 1000 mm.

Pontoons

Pontoons are used in storage tanks easily evaporating products and are designed to reduce the losses from evaporation. Pontoon must have supports that allow it to fix it in the two lower positions - work and repair. .

Platforms, transitions, stairs, fences

The vertical steel tank must be equipped with platforms and stairs. The tanks with a stationary roof must have a circular area on the roof or wall that provides access to the equipment located around the perimeter of the roof, and the staircase for lifting the circular platform, as well as, if necessary, additional areas on the roof and on the wall.

Stairs apply:

• ring - Located along the wall of the reservoir
• mine - separately standing. The height of the wall of the RVS-100 allows you to use single-hour mine stairs.

In order to prevent the stairs to prevent the stairs, must be made of lattice metal.

A shaft staircase with an annular element with a diameter of at least 2.6 m can be used as a frame for retrieving roll-up cloths during transportation.

Material performance of RVS-100

For the manufacture of metal structures of the RVS, steel are used that meet the requirements of the current standards and the one as well as the requirements of project documentation.

The design elements of the RVS-100 are divided into the following groups:

• A (main designs) - Wall, welded to the walls of the bottoms of the bottom or coloring bottoms, shelves of hatches and nozzles in the wall and flanges to them. enhancing lining, supporting rings of stationary roofs, rigidity rings, lining plates on the wall for fastening structural elements;
• B 1 (main designs) - roof frame, frameless roofs;
• B 2 (basic designs) - central part of the bottom, pontoons, anchor attachments, shelling of nozzles and hatches on the roof, hatch covers;
• B (auxiliary structures) - Stairs, platforms, transitions, fences.

For the group A, only calm, completely stretched steel apply. For group B use calm or semi-luminous steel. For auxiliary structures, along with the above steels, taking into account temperature conditions operation is allowed to use boiling steel.

The final selection of steel grades for the main elements of the structures are made taking into account the guaranteed minimum yield strength, rolling thickness and shock viscosity.

Equipment RVS-100 m 3

Depending on the characteristics of the stored product, the tank is equipped with various purposes:

• ventilation and respiratory (valves, nozzles),
• measuring and signaling (level gauges different types, level sensors, samplers),
• fireman (emergency fire extinguishing system, foam generators, irrigation systems),
• safety (clapboards with control mechanisms)
• devices / pouring devices (reuse, floating intake devices),
• other technological equipment (Devices for the erosion of bottom sediments, siphon cranes of the plug of bedding water, etc.)

If it is necessary to store products with high viscosity, heating system (registers and pipelines inside the tank) and thermal insulation can be added.

Recoversion settings can be used to increase the safety of the product.

RVS-100 protection against corrosion

The degree of aggressive impact of the medium on the elements of metal structures inside the tank and its external surfaces on open airmay vary. Therefore, the project of anti-corrosion protection of RVS-100 reservoirs is developed taking into account the characteristics of the design, alleged operating conditions and the desired service life.

To protect the metal constructions, corrosion tank mainly use paint coatings, as well as electrochemical protection systems using tread or cathode protection installations. It is possible to use other types of anti-corrosion coatings.

To increase the service life of the reservoir, an increase in the thickness of the main elements of the structures (wall, bottom, roofs, stationary and floating, pontoons) due to capacity for corrosion are used. Corrosion allowance is also varied depending on the aggressiveness of the medium.

Life time protective coatings Must be at least 10 years.
