Product Description

Seamless steel pipe   is a kind of strip steel. Steel pipe with hollow cross-section, a large number of pipes used to transport fluid, such as the transportation of oil, natural gas, gas, water and some solid materials such as pipes. Steel and round steel and other solid steel compared to the same bending strength in the same bending, lighter weight, is an economic section of steel, is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, Bicycle frames and steel construction scaffolding. The use of carbon seamless steel pipe manufacturing ring parts can improve material utilization, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe.
