Seamless steel pipes are made of a single piece of metal and have no seams on the surface. They are called seamless steel pipes. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, jacked pipes, etc. According to the cross-sectional shape, seamless steel pipes are divided into two types: circular and special-shaped. Special-shaped pipes have square, oval, triangle, hexagonal, melon-shaped, star-shaped, and finned pipes in various complex shapes. The maximum diameter is 650mm, and the minimum diameter is 0.3mm. According to different uses, there are thick-walled tubes and thin-walled tubes.
