Hot Selling S355JR Q235B Hollow Section Welded Carbon Steel Round Tube
Seamless Steel Pipe Processing
There are two main production processes for seamless steel pipes (cold rolling and hot rolling):
①Main production process of hot-rolled seamless steel pipe (△main inspection process):
Tube billet preparation and inspection△→tube billet heating→perforation→tube rolling→pipe reheating→fixed (reduced) diameter→heat treatment△→finished tube straightening→finishing→inspection△(non-destructive, physical and chemical, bench inspection)→in storage
②Main production process of cold-rolled seamless steel pipe:
Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection → storage
Carbon steel has high strength, good plasticity and toughness. It belongs to the comprehensive mechanical properties of good steel, with very broad, mainly used to make the load of the larger small cross-section conditioning large normalizing and stress smaller parts, and of the request is not high intensity of surface quenching parts, such as the spindle, crank shaft, shaft, gear, worm, keys, pins, etc. Water quenching has a tendency to form cracks, and parts with complex shapes should be hardened in hot water or oil.
