Carbon steel welded pipe is a common metal welding products, is the use of hot and cold rolled sheet coil or steel strip after forming and welding into a pipe a steel pipe. According to different forming methods and welding methods, carbon steel welded pipe can be divided into straight seam welded pipe and spiral welded pipe two types. Usually used to transport gas, liquid, solid powder or bulk materials.

The carbon steel seamless steel pipe is made of a whole piece of metal and has no seam on the surface.According to the production method,seamless pipes are divided into hot tube, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking and so on. The carbon seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler tubes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
