  Seamless steel pipe is widely used. The seamless steel pipe used for general use are rolled by ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the most output, which are mainly used as pipes or structural parts for conveying fluid. According to different uses, it can be divided into three types: A. supply according to chemical composition and mechanical properties; B. supply according to mechanical properties; C. supply according to hydraulic test. Seamless steel pipes supplied by class A and B shall also be subjected to hydraulic pressure tests if they are used for liquid pressure. Special purpose seamless steel pipes include seamless pipes for boilers, chemical and electric power, geological seamless pipes and petroleum JIS G3445 Cold Drawn Carbon Seamless Steel Pipe.

  Seamless steel pipe have hollow sections and are widely used as pipes for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, the steel tube has lighter weight and is an economic section steel at the same bending and torsion strength.

  It is widely used in the manufacture of structural parts and mechanical parts, such as oil drilling rod, automobile drive shaft, bicycle frame, and steel scaffold used in construction. It can improve the utilization of material, simplify the manufacturing process, save materials and work, and have widely used steel tube to make it.
