Pressure vessel manufacturing, liquefied gas storage tank price, Shandong high-quality supplier

Description :

　　Classification of storage tanks:Storage tanks can be divided into full pressure storage tanks, semi refrigerated storage tanks, and fully refrigerated storage tanks according to their liquefaction forms; According to the volume change of the container, it can be divided into two types: fixed volume storage tanks and movable volume storage tanks. Large fixed volume storage tanks are made into spherical shapes, while small ones are made into cylindrical shapes; According to the buried method, it can be divided into underground storage tanks and above ground storage tanks. Among them, full pressure storage tanks are more common.

　　1、 Introduction to Full Pressure Storage TanksThe characteristic of a storage tank stored at room temperature is that the storage pressure varies with the ambient temperature.

　　2、 Risk Analysis of Full Pressure Storage Tanks

　　(1) Fire and explosion: 1) Failure to follow the hot work regulations when conducting open flame operations in areas with fire and explosion hazards.

　　2) The operator did not use tools such as explosion-proof hammers and wrenches.

　　3) Improper selection of explosion-proof electrical equipment based on the hazardous characteristics of the substance.

　　4) Reliable lightning protection facilities and effective measures to eliminate static electricity have not been established.

　　5) The protection range of the combustible gas alarm in the storage tank area is insufficient, and it cannot be detected in a timely manner. When encountering an ignition source, it may lead to fire and explosion accidents. (2) Container explosion

　　1) In summer, the ambient temperature rises and there are no effective pressure reduction measures for the storage tank, resulting in container explosions.

　　2) The pressure gauge was damaged and did not effectively reflect the pressure inside the storage tank, resulting in the failure to take effective measures to reduce the tank pressure.

　　3) The pressure rises and the safety valve of the storage tank cannot be effectively opened, causing the container to explode.

　　4) Failure of safety protection devices for equipment and facilities, including failure or malfunction of safety valves, explosion-proof valves, explosion-proof discs, pressure relief valves, alarm systems, etc. for storage tanks.

　　(3) Poisoning and suffocation: 1) Leakage caused by aging and damage of equipment and facilities; 2) Insufficient installation height of relief valves, resulting in poisoning and suffocation of operators.

　　3、 Preventive measures for full pressure storage tanks

　　(1) When conducting open flame operations in areas with fire and explosion hazards, the hot work system should be followed.

　　2) Operators use tools that do not generate sparks.

　　3) Select explosion-proof electrical equipment of grade IIA, T2 and above.

　　4) Set up reliable lightning protection facilities and effective measures to eliminate static electricity, and conduct lightning protection testing every six months.

　　5) The release source should be located in the equipment area of an open-air or open factory layout, and the horizontal distance between the combustible gas detector and any release source within its coverage area should not be greater than 10m.

　　(2) Container explosion 1) The storage tank should be equipped with a water spray cooling device, and the water supply should meet the requirements.

　　2) Safety accessories (pressure gauges, safety valves, combustible gas alarms, etc.) should be regularly inspected to ensure they are within their validity period.

　　3) The use of pressure vessels should be registered and regularly tested to ensure that they are within their validity period.

　　(3) Poisoning and suffocation: 1) Regular maintenance and testing of equipment and facilities to ensure good operation of the equipment.

　　2) The discharge pipe mouth of the safety valve of the above ground storage tank should be at least 2 meters higher than the storage tank operating platform and at least 5 meters higher than the ground; The discharge pipe of the safety valve for underground storage tanks should be at least 2.5 meters above the ground.
