Product introduction：

Seamless steel pipe is made of whole round steel perforated, the surface of the steel pipe without weld, called seamless steel pipe.

 According to the production method, the seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, 

cold drawn seamless steel pipe, extrusion seamless steel pipe, pipe jacking and so on. The maximum diameter is 900mm and the minimum diameter is 4mm. 

According to different uses, there are thick wall seamless steel pipe and thin wall seamless steel pipe.

 Application：

Seamless steel pipe has hollow section and is widely used as the pipeline for conveying fluids, such as the pipeline for conveying oil, natural gas, gas,

 water and some solid materials. Compared with solid steel such as round steel, 

steel pipe is a kind of economic section steel because of its light weight and the same bending and torsional strength.

It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, 

bicycle frame and steel scaffolding used in construction. It can improve the utilization rate of materials, 

simplify the manufacturing process, save materials and processing hours, and has been widely used in the manufacture of steel pipe.
