The pressure vessel is a comprehensive product involving many industries and multi disciplines. Its construction technology involves many industries such as metallurgy, mechanical processing, corrosion and corrosion protection, non-destructive testing, and security protection. Pressure vessels are widely used in chemical, petroleum, machinery, power, metallurgy, nuclear energy, aviation, aerospace, marine and other sectors. It is an indispensable core equipment in the production process and an important symbol of a country's equipment manufacturing level. For example, reaction devices in chemical production, heat exchange devices, housings for separation devices, gas-liquid storage tanks, pressure shells for nuclear power reactors, and steam drums in power plant boiler systems are pressure vessels. With the continuous advancement of metallurgy, mechanical processing, welding and non-destructive testing technologies, especially the rapid development of information technology represented by computer technology, it has driven the development of related industries and has invested a large amount of manpower and material resources in various countries of the world for in-depth research. Based on this, pressure vessel technology has also made corresponding progress.

Container refers to the basic device that is used to contain materials and is mainly shell-based. Often used as a housing for storage equipment or other chemical equipment. Mainly by the shell, head, pipe, flanges and bearings. The basic requirements for containers are: to meet process requirements; to ensure operational safety, including adequate strength, rigidity and tightness; corrosion resistance, a certain service life; easy to manufacture, install, repair and use; low cost, material savings, In particular, precious materials such as stainless steel and non-ferrous metals should be saved. Containers are widely used in chemical production. There are vacuum, normal pressure and external pressure pressure vessels according to pressure. Pressure vessels can be divided into low pressure, medium pressure, high pressure and ultra-high pressure vessels. Temperature, low temperature and high temperature vessels can be divided by temperature. According to the structure of the cylinder, there are single-layer containers and multi-layer containers; there are storage, separation, reaction and heat exchange containers according to the process purpose; thin-walled and thick-walled containers are divided by thickness.
