ActiveStatic vacuum insulated cryogenic pressure vessels— Part 7：Rules of pressure strengthening for inner vessels
固定式真空绝热深冷压力容器 第7部分：内容器应变强化技术规定
Application Summary AI generated
This standard specifies the technical requirements for pressure strengthening of inner vessels in static vacuum insulated cryogenic pressure vessels. It is applied in the manufacturing and testing of cryogenic storage tanks for liquefied gases such as LNG, liquid oxygen, and liquid nitrogen, ensuring the inner vessel can withstand higher pressures through controlled strain hardening. The rules are used by engineers and quality inspectors in the industrial gas, energy, and chemical sectors to validate vessel integrity and safety before service.
