12" Sch60 Alloy Seamless Steel Pipe Gr P5 High Temperature
15crmo 12" Sch60 Seamless Alloy Steel Tube Hot Rolled for High Pressure Boiler
Introduction
Alloy seamless steel pipe is a kind of seamless steel pipe, its performance is much higher than that of general seamless steel pipe, because this kind of steel pipe contains more Cr, its high temperature, low temperature and corrosion resistance performance is not compared with other seamless steel pipe, so alloy pipe is widely used in petroleum, chemical industry, electric power, boiler and other industries.
Alloy seamless steel pipe contains elements such as silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron, rare earth, etc.
Production process
Hot rolling (extruded seamless steel pipe): pipe billet → heating → perforation → three-roll oblique rolling, continuous rolling or extrusion → pipe → diameter (or diameter reduction) cooling pipe straightening → hydraulic test (or flaw detection) marking → storage.
cold drawn (rolled) seamless steel tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating), multi-pass cold drawing (cold rolling)→ billet tube → heat treatment, straightening → water pressure test (flaw detection), marking → storage
