Seamless Steel Pipe Process
The production process can be determined according to the end use of the product. There are two main processes for producing seamless steel pipes, namely cold drawing and hot rolling. Cold drawing is to draw the steel pipe through a drawing die to gradually thin and elongate the steel pipe. Hot rolling is to heat the tube blank and extrude it into a tube with an extruder until the pipe reaches the desired diameter and wall thickness. Therefore, seamless carbon steel pipes do not have longitudinal welds.
