Premium 10000L Carbon Steel Pressure Vessel for Oil Refining Applications

Atmospheric Pressure Vessels

Design pressure range -0.02—0.1MPa.
Structural forms of atmospheric pressure storage tanks:
horizontal container, vertical cylindrical container, vertical cylindrical storage tank.

Horizontal Pressure Vessels

Structural features

Usually a horizontal cylindrical shape, generally using a saddle support. The connection between the saddle support and the base can be divided into fixed and sliding types. The sliding type can reduce the thermal stress of the equipment. Different internal components can be set according to needs.

Advantages

①Good stability: Horizontal placement makes the center of gravity of the container lower, and it has better stability during storage and transportation, and is not easy to tip over. It is especially suitable for storing high liquid levels or easy-to-flow liquids.

②Easy to install: The installation height of the horizontal container is low, the installation process is relatively simple, the space requirement for the installation site is relatively small, and it is easy to maintain and overhaul.

③Easy to operate: It has advantages in operation, such as the installation and operation of equipment such as level gauges and inlet and outlet valves are easier to approach and carry out, which is convenient for daily inspection, maintenance and management.

Vertical Cylindrical Pressure Vessels

Structural features

It is an upright cylindrical container, consisting of a cylindrical body and upper and lower heads. The heads are usually elliptical, disc-shaped or conical to meet different process requirements and stress conditions. It is generally supported on the foundation by a skirt or legs. According to the storage medium and process requirements, a variety of components can be set inside.

Advantages

① Small footprint: The vertical cylindrical container has a relatively small footprint with the same storage volume, which can effectively utilize the space and is particularly suitable for places with limited space, such as gas stations in cities and small storage areas in chemical parks.

②High liquid storage efficiency: Due to its shape characteristics, the liquid in the vertical container is distributed more evenly under the action of gravity, which is conducive to improving the storage efficiency and quality stability of the liquid. At the same time, for some occasions where liquid level control or metering is required, the liquid level measurement and control of the vertical container are relatively accurate and convenient.

Vertical Cylindrical Storage Tanks

Vault storage tank: divided into plain shell vault, ribbed shell vault, lattice shell vault, mainly used to store low-volatility, non-toxic liquid products

Cone roof storage tank: suitable for storing some liquid products with high drainage requirements, such as liquids containing a small amount of water or impurities

Floating roof storage tank: storage of oil products such as crude oil, etc., whose quality is not greatly affected by rainwater and other impurities

Internal floating roof storage tank: the internal part of the external vault is a floating roof, and the floating roof material is steel and aluminum. It is mainly used to store volatile finished oil, such as aviation kerosene, gasoline, etc.

Advantages

①Uniform and reasonable force: The wall of the vertical cylindrical storage tank evenly bears the pressure of the liquid, and the stress distribution is relatively uniform. Compared with other shapes of storage tanks, it can better withstand internal and external pressures, reduce the safety risks of rupture or deformation of the storage tank, and can be used to store media with different pressure requirements.

②Easy to construct: Its structural shape is regular, and it is easy to use standardized processes and equipment during the manufacturing process. The construction is relatively simple, which can improve construction efficiency and reduce construction costs. At the same time, this regular shape is also convenient for installing various auxiliary equipment, such as liquid level gauges, thermometers, import and export pipes, etc.

③Easy to maintain and manage: The external structure of the vertical cylindrical storage tank is relatively simple, which is convenient for daily inspection, maintenance and maintenance. The staff can easily patrol around the storage tank, and promptly discover and deal with possible problems, such as tank corrosion and leakage, which is conducive to ensuring the safe operation of the storage tank.
