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.

JIS G3455 STS 370 Carbon Steel Pipe is a high-strength, high-corrosion-resistant carbon steel pipe with excellent mechanical properties and welding properties.

The hot expanding steel pipe is hot expanded seamless pipes, which is relatively low density but the contraction of the strong steel pipe (seamless pipe) can be referred to as thermal expansion.
