A672 B65 steel tube
The pipes supplied by GNEE undergo multiple inspections to ensure quality, with outer diameters ranging from 457-1422mm and wall thicknesses from 2-60mm or even thicker.
What are the advantages of using A672 B65 carbon alloy steel pipe?
The advantages of using A672 B65 carbon steel welded pipe include high strength-to-weight ratio, good weldability, ductility and toughness, resistance to corrosion and atmospheric conditions, ease of installation and maintenance, economical cost compared to other materials, etc.
A672 B65 is an electric welded steel pipe material, which is a low-temperature alloy steel pipe and is mainly composed of carbon, manganese, silicon, tungsten, nickel, vanadium and other elements. Compared with A672 B60, A672 B65 has a slightly higher carbon content, so it has higher yield strength and tensile strength. It is suitable for industrial environments with higher temperatures and higher pressures, usually for gas storage tanks and gas pipelines, LNG plants and other industrial equipment in low-temperature environments.
