A106 Gr.B carbon steel seamless pipe is made by cold drawing or hot rolling, without welds. Compared with ordinary steel pipes that are welded after bending flat plates, it avoids the problems that may occur at the welds, and there will be no different diameters of different parts caused by welds, which can effectively prevent problems such as pipeline ground collapse or affecting other components.
A53 GR.B seamless steel pipe is mainly made by extrusion reducing process, which is a continuous coreless profile rolling process. Under the premise of ensuring welding quality, the welded steel pipe is subjected to extrusion reducing process, the steel pipe is heated to above 950 degrees Celsius, and then rolled into finished steel pipes of various outer diameters and thick walls through an extrusion reducing mill. In addition, this steel pipe is also suitable for general-purpose piping systems.
