Gas storage tank refers to equipment specially used to store gas, and at the same time, it stabilizes the pressure of the system. According to the pressure of the gas storage tank, it can be divided into high pressure gas storage tank, low pressure gas storage tank, and normal pressure gas storage tank. There are different types of gas storage tanks: carbon steel gas storage tanks, low-alloy steel gas storage tanks, and stainless steel gas storage tanks. According to pressure: low pressure gas storage tank, medium pressure gas storage tank, high pressure gas storage tank. The gas storage tank (pressure vessel) is generally composed of parts and components such as a cylinder, a head, a flange, a pipe, a sealing element, and a support. In addition, it is also equipped with safety devices, meters and internal parts for different production processes.
