Seamless Pipe

The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface. It is mainly used as high-precision structural steel pipes for petrochemical industry, boiler pipes, automobiles and aviation. Seamless tubing can be made from any of several alloys and metals, such as carbon steel, stainless steel, molybdenum, or tungsten. Seamless pipes are used in those industrial applications that require the highest safety requirements. To produce seamless steel pipes, the solid block is pierced with a piercing plug before the pipe is drawn to the desired size. Some of the differences between seamless and welded pipes are: Seamless pipes are extruded and drawn from billets, while welded pipes are produced from roll formed and welded strips
