Research Progress of Lightweight Design & Manufacture Technology of Heavy Pressure Vessels in China
摘要
Abstract
Nowadays,lightweight technology of heavy pressure vessel is regarded as an important measure for resource conservation in production all over the world. The research progress of lightweight technology of heavy pressure vessels in China is introduced in this paper in three aspects. Firstly, Chinese government revised TSG R0004—2009 "Supervision Regulation on Safety Technology for Stationary Pressure Vessel" in 2009,where the safety factor of tensile strength in conventional design is reduced from 3. 0 to 2.7. Meanwhile,corresponding revision was also made to GB 150—2011"Pressure Vessels". The influence possibly brought by these adjustments on safety of pressure vessels is analyzed and associated resolutions are proposed in this paper. Secondly, the research progress of application of high strength steels in pressure vessel construction, the technical difficulties and their resolution ways are introduced. The typical case is introduced which is the application of 490 MPa grade high strength steel with low weld cracking sensitivity in the construction of large - sized cryogenic ethylene spherical tank. Finally, the research progress of strain strengthening technology for austenitic stainless steel is introduced,including the suitability of Chinese domestic steels and the effect of strain strengthening process on pressure vessel life and reliability.关键词
