Research on Localization of ASTM Seamless Steel Pipe for Low-temperature Service

Based on ASTM A 333/A 333M, discussed in the essay are the current situation of localization of ASTM seamless steel pipe for low-temperature service, and the product quality, and present applications of such pipes as made at home.As a result of the analysis, it is regarded that the localization of Gr1, Gr3, Gr6 and Gr8 pipes have been realized, and the supply system for domestically-made ASTM seamless steel pipes for service under the lowest temperature as-195℃ has been established.Accordingly it is suggested to make transformation of the localization from ASTM A 333/A 333M pipes to ASTM A 334/A 334M pipes, so as to promote localization of the pipe for low-temperature piping service to that of the pipe for low-temperature heat exchanger service in a bid to expand the market places of the domestically-made ASTM seamless steel pipe for low-temperature service.
