Hot Rolled 20inch Alloy Seamless Steel Pipe Astm A335 P91 Sch60

Alloy Steel Seamless Pipe Hot Rolled Steel Pipe Astm A335 P91 20" Sch60

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.
Alloy seamless steel pipe (Seamless Steel Tube) with hollow section, no joints around the strip steel. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe is light weight when bending and torsion strength is the same. It is an economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil conveying, stair handrails, bicycle frames and steel scaffolding used in construction. Making ring parts with alloy seamless steel pipe can improve material utilization, simplify manufacturing process, and save material and processing time, such as rolling bearing ring, Jack sleeve and so on. Steel pipe has been widely used to manufacture. Alloy seamless steel pipe or all kinds of conventional weapons indispensable materials, gun barrel, barrel and so on must be made of steel pipe. In addition, when the ring section is subjected to internal or external radial pressure, the force is more uniform, so most alloy seamless steel tubes are circular tubes
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
