What is seamless pipe?(also called seamless steel pipe,seamless tube,seamless steel tube)
Made of a single piece of metal, the surface is not seamed steel pipe, known as the seamless pipe. According to the production method, seamless pipe sub-hot-rolled tubes, cold-rolled tubes, cold drawn tubes, extruded tubes, pipe jacking. According to the cross-sectional shape, seamless steel pipe is divided into two types: circular shape and irregular shape. There are many complex shapes such as square, oval, triangle, hexagon, melon, star and winged pipe. The maximum diameter of 650mm, the minimum diameter of 0.3mm. According to different purposes, there are thick-walled tubes and thin-walled tubes. Seamless steel pipe is mainly used for petroleum geological drilling pipe, petrochemical cracking pipe, boiler tubes, bearing tubes and automotive, tractor, aviation high-precision structural steel.
