GB6479 steel pipe application

GB6479 steel pipes are mainly used for straight seam welded steel pipes for mine compressed air, drainage, and shaft discharge gas.
Its representative material is Q235A and B grade steel. GB/T14980-1994 (large-diameter electric-welded steel pipes for low-pressure fluid transportation).
Boiler tubes are mainly used for conveying water, sewage, gas, air, heating steam and other low-pressure fluids and other purposes. Its representative material is Q235A grade steel.

GB6479 steel pipe process

Hot rolling (extruded seamless steel pipe): round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or reducing) → cooling → billet tube → straightening → quality inspection Wall thickness→hydraulic test (or flaw detection)→marking→storage.
Cold drawn (rolled) seamless steel pipe: round tube blank→heating→perforation→heading→annealing→pickling→oiling (copper plating)→multi-pass cold drawing (cold rolling)→blank tube→heat treatment→straightening→ Quality inspection wall thickness→hydraulic test (flaw detection)→marking→storage.
