carbon steel pipe

The steel pipes are divided into seamless steel pipes and welded steel pipes. The production process of seamless steel pipe is to thread solid tube blank or steel ingot into hollow capillary, and then roll it into steel pipe of required size. Different piercing and rolling methods are used to produce seamless steel tubes. The production process of welded steel pipe is to bend the tube blank (steel plate or strip) into a tube, and then weld the gap to become a steel pipe. Different forming and welding methods are used to produce welded steel pipes.
