Alloy pipe is a steel pipe according to the production materials (i.e. material) to define, just as its name implies is made of alloy steel seamless pipe; and is in accordance with the production process (seamed seamless) to define, seamed pipe seamless pipe is different from, including straight seam welded pipe and spiral tube.

Manufacturing process

1 hot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll cross rolling, rolling or extrusion, tube off, sizing pipe (or reducing), cooling, straightening, water pressure test (or testing), marking, storage

2 cold drawing (rolling) seamless steel pipe: billet, heating, perforation, heading, annealing, pickling, oiling round tube (copper) and multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, water pressure test (testing), marking, storage

[(diameter - thickness) * wall thickness of]*0.02466=kg/ meters (per metre weight)

Alloy pipe use

Alloy pipe for low and medium pressure boiler (work pressure is generally not more than 5.88Mpa, the operating temperature at 450 DEG C) of the heating surface tube; used for high pressure boiler (work pressure is generally above 9.8Mpa, operate at a temperature of 450 DEG to 650 DEG C between) the heating surface tubes, economizer, superheater, reheater, petrochemical industry uses the tube and so on.
