A106 Grade B Steel Pipe Description
A106 steel pipe is a low carbon steel pipe whose main components are carbon, silicon, manganese and small amounts of chromium, copper, nickel and molybdenum. It is a seamless steel pipe suitable for transporting liquids and gases in high temperature and high pressure environments. The manufacturing process of A106 steel pipe usually includes steps such as hot rolling, cold drawing and cold working. During these processes, the internal structure of the pipe is made tighter through heat and pressure treatment, thereby improving its strength and corrosion resistance. A106 steel pipe can be used in many different fields, such as oil, natural gas, chemical industry, electric power, shipbuilding, aerospace, etc..
