ASTM A333 Gr.1 Gr.6 Gr.8 Seamless Low-Temperature Pipes

The ASTM A333 standard specifies specifications and requirements for seamless and welded steel pipe for low and high temperature service. Among them, Gr.1, Gr.6 and Gr.8 are the three levels in the standard, indicating different mechanical properties and chemical composition respectively. These seamless cryogenic pipes have excellent low-temperature toughness, corrosion resistance and mechanical properties, can maintain stable performance at extremely low temperatures, and are widely used in cryogenic pipeline systems in oil, natural gas, chemical, electric power and other industries.
