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.
