Wholesale Hot Rolled Carbon Seamless Steel Pipe - GB8163 Line Steel Pipe Seamless Steel Pipe – Haihui
Short Description:
Wholesale Hot Rolled Carbon Seamless Steel Pipe - GB8163 Line Steel Pipe Seamless Steel Pipe – Haihui Detail:
Compared with solid steel such as round steel, the steel pipe is light in weight when the bending and torsion strength are the same. It is an economical cross-section steel and is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. Manufacturing ring-shaped parts with steel pipes can improve the utilization rate of materials, simplify the manufacturing process, and save materials and processing hours, such as rolling bearing rings and Jack sleeves. At present, steel pipes have been widely used for manufacturing. Steel pipe is also an indispensable material for all kinds of conventional weapons. The barrel and barrel of guns are made of steel pipe. Steel pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional areas and shapes. Since the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipes. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform. Therefore, the vast majority of steel pipes are round pipes.

Hot rolling (extruding seamless steel pipe): round tube blank → heating → piercing → three roll cross rolling, continuous rolling or extrusion → pipe stripping → sizing (or reducing) → cooling → blank tube → straightening → hydrostatic test (or flaw detection) → marking → warehousing.
Cold drawn (rolled) seamless steel pipe: round tube billet → heating → perforation → heading → annealing → pickling → oil coating (copper plating) → multi pass cold drawing (cold rolling) → billet → heat treatment → straightening → hydrostatic test (flaw detection) → marking → warehousing.
