Carbon seamless steel pipe is a kind of long steel pipe. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, carbon seamless steel pipe has the same bending and torsional strength, and is lighter in weight. It is an economical section steel. Carbon seamless steel pipe is widely used in the manufacture of structural parts and mechanical parts, such as petroleum Drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction, etc.

The use of carbon seamless steel pipe to manufacture annular parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipe manufacturing.
Carbon seamless steel pipe is also an indispensable material for various conventional weapons. Steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Since the area of ​​the circle is the largest under the condition of equal perimeter, more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Therefore, most steel pipes are round pipes.
Using Carbon seamless steel pipe to manufacture annular parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., carbon seamless steel pipe has been widely used to manufacture at present.
