Mechanical Seamless steel pipe for machining is one of the most commonly used types of seamless steel pipes. The seamless steel pipe has a hollow section and no welds from beginning to end. Compared with solid steel such as round steel, the seamless steel pipe for machining 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, Bicycle racks and steel scaffolding used in construction.

Mechanical Seamless steel pipe for machining manufactures ring-shaped parts, which can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., which have been widely manufactured with steel pipes. Mechanical Seamless steel pipe for machining is still an indispensable material for all kinds of conventional weapons. Gun barrels and barrels are all made of steel pipes. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported with a circular tube. In addition, when the ring section bears internal or external radial pressure, the force is relatively uniform. Therefore, most steel pipes are round pipes.
