The use of pressure vessels is very wide. It is an equipment that plays an important role in various sectors of the national economy such as the petrochemical industry, energy industry, scientific research and military industry.
The pressure vessel is generally composed of six parts: a cylinder, a head, a flange, a sealing element, an opening, a nozzle, and a support. In addition, it is also equipped with safety devices, meters and internal parts to complete the role of different production processes. Due to reasons such as sealing, pressure bearing and medium, pressure vessels are prone to explosions, fires and accidents that endanger the safety of personnel, equipment and property, and pollute the environment.
