Carbon 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.
