Seamless steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe is lighter when the bending and torsion strength is the same. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, and bicycles. Frames, rolling bearing rings, jack sleeves, etc., have been widely made of steel pipes.
Material: 10#, 20#, 45#, 16Mn, 27SiMn, 12Cr1MoVG, 15CrMO, 15CrMoG., 20G, 40Cr and other seamless steel pipes of various materials.
