As daily life and an integral part of the machinery industry products, steel, maybe a lot of people are not quite sure where it's main application, here we are with a rectangular steel pipe, for example, to introduce its main applications:
   Steel is widely used in the manufacture of mechanical parts and structural components, such as drill pipe, bicycle frames and construction using steel scaffolding. Ring with a steel pipe manufacturing parts, can improve material utilization, simplify the manufacturing process, saving material and machining time. Steel or conventional weapons indispensable material, gun barrels to make steel.
   Pipe future focus should be on full use of the capacity of existing units, the development of high-strength grade, high resistance to corrosion of oil pipes and cylinders pipe and other products.
