Product Description

 Carbon steel pipe

 

Product Description

   The seamless steel pipe has a 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 has the same bending and torsional strength and is light in weight. It is a kind of economic cross-section steel, 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. Steel pipes have been widely used to make them.
