Product Description

Compared with solid steel such as round steel, tubes for fluid transport are lighter in weight when the bending and torsion strength is the same, and they are a kind of economic cross-section steel, which is widely used to manufacture structural and mechanical parts, such as oil drilling rods, automobile drive shafts, bicycle frames and steel scaffolding used in building construction. With steel pipe manufacturing ring-shaped parts, can improve the material utilisation rate, simplify the manufacturing process, save materials and machining hours, such as rolling bearing rings, jack sets, etc., has been widely used in the manufacture of fluid transport pipe.Standard:GB/T8163--Chinese national standardAPI 5L --American Petroleum Institute (API) standardUsage:General seamless steel pipe for the transportation of fluidsMain production steel pipe grade: 10,20,Q345,Q390,Q420,Q460,Gr.B-X70, etc.
