ASTM SA/A106 seamless carbon steel pipe is a kind of seamless steel pipe widely used in high temperature and high pressure environment.

ASTM A672 B70 carbon steel EFW (electric arc furnace smelting) pipe is a stainless steel pipe that complies with the American ASTM standard. It is mainly used for the transportation of media such as steam, water, oil and other media in high temperature and high pressure environments. This kind of pipe has a high carbon content, good strength and corrosion resistance, and is suitable for long-term use in various harsh environments.

ASTM A790 UNS S31803 stainless steel pipe is a high performance duplex stainless steel material with excellent corrosion resistance, high strength and good machinability.

SUS630 also known as 17-4PH, is a high-strength, corrosion-resistant martensitic stainless steel alloy.
