Crude Oil Storage Tank
Steel sealed containers used to store liquid crude oil or natural gas are crude oil storage tanks. Steel tanks are essential infrastructure for storing oil and natural gas, including high-pressure gas tanks, dome roof tanks, floating roof tanks and underground Storage tank. Storage tanks are commonly used in refineries, oil fields, oil depots, and other industries. The oil tank farm consists of multiple oil tanks. Each oil tank farm typically stores one type of oil product.
Abundant manufacturing experience in Crude Oil Storage Tank.
Can be used for factory prefabrication, providing great convenience for on-site construction.
According to user needs, products with different size can be customized, ranging from 100 to 3000 m3.
Multiple wall thicknesses and pressure levels to meet different working conditions and safety requirements.
Crude Oil Storage Tank, referred to as oil tank or storage tank, is a large container with regular shape for storing oil products. It can be divided into metal oil tank and non-metal oil tank according to different construction materials. Most metal oil tanks are steel tanks, which are commonly used in oil depots at present. Non metallic oil tanks, also known as earthen oil tanks, have been gradually phased out since the 1990s due to safety hazards.
Crude Oil Storage Tanks include vertical (including dome and floating cylindrical), spherical (spherical), and horizontal (cylindrical) tanks. The vertical dome roof oil tank is composed of a spherical crown shaped tank top and a vertical cylindrical tank wall, mainly used for storing non volatile oil products, such as diesel and similar oil products. The most commonly used volume is 1000-3000 m ³.
A floating roof oil tank is composed of a floating roof and a vertical cylindrical tank wall that floats on the surface of the medium. The floating roof rises and falls with the increase or decrease of the storage capacity of the medium inside the tank. There is a circular sealing device between the outer edge of the floating roof and the tank wall, and the medium inside the tank is always directly covered by the inner floating roof, reducing the volatilization of the medium. Mainly used for storing volatile oil products, such as gasoline and similar oil products. The volume of floating roof oil tanks is generally relatively large. Floating roofs are divided into single disc floating roofs, double disc floating roofs, and float floating roofs.
Horizontal oil tanks are composed of end caps and horizontal circular or elliptical tank walls, usually used in production processes or gas stations. The volume of horizontal oil tanks is generally less than 100m³.
(1) Dome roof storage tanks are widely used in many industries worldwide due to their simple manufacturing and low cost. The following is a typical Dome roof storage tank.
(2) Floating roof storage tanks are composed of floating roofs and vertical cylindrical tank walls that float on the surface of the medium. The floating roof rises and falls with the increase or decrease of the storage capacity of the medium inside the tank. There is a circular sealing device between the outer edge of the floating roof and the tank wall, and the medium inside the tank is always directly covered by the inner floating roof, reducing the volatilization of the medium.
Tank bottom: The volume of floating roof tanks is generally relatively large, and their bottom plates are all made of arched edge plates.
Tank wall: The straight tank wall should be used, and the butt welds should be polished smooth to ensure a flat inner surface. The upper part of the floating roof storage tank is open. To increase the stiffness of the wall panel, wind resistant ring beams and reinforcing rings should be installed on the top of the tank wall according to the wind load in the area.
Floating roofs are divided into outer floating roofs and inner floating roofs. Generally speaking, what is uncovered on a floating roof is an external floating roof, and what is covered is an internal floating roof.
The materials required for tank engineering are divided into tank body materials and auxiliary facility materials. Tank materials can be divided into low strength steel and high strength steel based on tensile yield strength or tensile standard strength. High strength steel is mostly used for storage tanks with a capacity of over 5000 m³. Auxiliary facilities (including wind resistant ring beams, locks, winding ladders, guardrails, etc.) are all made of ordinary carbon structural steel with lower strength, while other accessories and accessories are made of other materials according to different purposes. The commonly used domestic steel materials for manufacturing tank bodies include 316L, 304L, 20, 20R, 16Mn, 16MnR, and Q235 series. Sanjack can choose corresponding materials according to different user needs
To ensure the safety and smoothness of product use, Sanjack storage tank is also equipped with the following measures
Auxiliary equipment
In order to facilitate the transportation of oil products, heaters are installed inside the tanks for storing heavy oil and crude oil, and insulation measures should also be taken on the outside of the above ground tank walls. According to production, maintenance, and safety requirements, the oil tank is equipped with: ① oil measuring holes (also used as sampling holes); ② Oil tanks for storing gasoline, kerosene, light diesel, crude oil, and aromatics need to be equipped with breathing valves; ③ Oil tanks storing heavy oil products such as fuel oil, raw material oil, heavy diesel oil, and wax oil need to be equipped with ventilation holes; ④ Manholes, transparent holes, and cleaning holes (the latter is only set in heavy oil tanks).
