How Seamless Steel Pipe Process

Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.

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.

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
