Alloy seamless steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe, because this steel pipe contains more Cr, and its high temperature resistance, low temperature resistance and corrosion resistance performance are better than other seamless steel pipes. Incomparable, so alloy pipes are widely used in petroleum, chemical, 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 tube (Seamless Steel Tube) has a hollow section, a long strip of steel without joints around it. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy seamless steel pipe has a lighter weight when the bending and torsional strength is the same. Bicycle racks and steel scaffolding used in building construction, etc. Making ring parts with alloy seamless steel pipe can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipe manufacturing. Alloy seamless steel pipe is also an indispensable material for various conventional weapons, and the barrel, barrel, etc. must be made of steel pipe. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform. Therefore, most alloy seamless steel pipes are round pipes. Alloy tube material 12Cr1MoV, P22 (10CrMo910) T91, P91, P9, T9, WB36, Cr5Mo (P5, STFA25, T5, )15CrMo (P11, P12, STFA22), 13CrMo44, Cr5Mo, 15CrMo, 25CrMo, 30CrMo, 40CrMo.
