Application of pressure vessel

Pressure vessels are widely used. It plays an important role in petrochemical industry, energy industry, scientific research and military industry. Pressure vessel is generally composed of cylinder, head, flange, sealing element, opening and connecting pipe, and support. In addition, it is equipped with safety devices, meters and internals with completely different production processes. Due to sealing, pressure bearing and medium, pressure vessels are prone to explosion, combustion and fire, which endanger the safety of personnel, equipment and property and pollute the environment. All countries in the world regard it as an important supervision and inspection product, and the special institutions designated by the state carry out supervision and inspection and technical inspection in accordance with the national regulations and standards.

Pressure vessel

Meanwhile, in the past 10 years, with the strong support of the Ministry of science and technology of the people's Republic of China and the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China and the joint efforts of the whole industry, China's pressure vessels have made great progress in the formulation and revision of standards and specifications, major product development, long-term safety guarantee, etc. AQSIQ has established a complete system composed of laws, regulations, rules, safety technical specifications and standards. In terms of design method, material, manufacturing and inspection technology, the field has established and improved the design method of pressure vessels based on risk and life, and proposed the lightweight design method of heavy pressure vessels. In terms of adapting to the extreme demand of pressure vessels, the relevant indicators are not lower than those of developed countries.

The implementation of "made in China 2025" is an important measure for China to realize the transformation from a big manufacturing country to a powerful manufacturing country“ The strategy includes 5 major projects and 10 key areas, all of which are closely related to pressure vessels. China's pressure vessel technology is facing new challenges from the national demand. Both industry and academia must think about it and develop new high-end equipment to meet the development needs of emerging process industries.
