Structural seamless pipe is used for general structure and mechanical structure seamless pipe. It is a variety of seamless steel pipe divided into different uses.
Structural stainless steel seamless pipe is widely used in chemical, petroleum, textile, medical, food, machinery and other industries of corrosion resistant pipes and structural parts and parts made of stainless steel hot rolled (extrusion, expansion) and cold drawn (rolled) seamless pipe.
Structural seamless pipe is mainly used in general structure and mechanical structure. Its representative material (grade) : carbon steel 20, 45 steel, Q235, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
Because of its different manufacturing processes, seamless steel pipes are divided into hot-rolled (extruded) seamless steel pipes and cold-drawn (rolled) seamless steel pipes. Cold drawn (rolled) pipe is divided into two kinds: round pipe and shaped pipe.
a. Process overview
Hot rolling (extruded seamless steel pipe) : round tube blank → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → Stripping → sizing (or reducing) → Cooling → Blank tube → straightening → hydraulic test (or inspection) → marking → storage.
Cold-drawn (rolled) seamless steel pipe: round tube billet → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → billet pipe → Heat treatment → straightening → hydraulic test (inspection) → marking → storage.
