Alloy steel pipe is mainly used in power plant, nuclear power plant, high pressure boiler, high temperature superheater, reheater and other high pressure and high temperature pipes and equipment. It is made of high quality carbon steel, alloy structural steel and stainless heat resistant steel by hot rolling (extrusion, expansion) or cold rolling (drawing).
Metal pipe and seamless pipe have connection and difference, can not be confused. Gold pipe is defined as steel pipe according to the production material (i.e., material). As the name implies, it is tube made of alloy. Seamless pipe is defined as steel pipe (seam and seamless) according to the production process.
Alloy pipe is a kind of seamless steel pipe, which is divided into structural seamless pipe and high pressure heat resistant alloy pipe. Mainly different from the production standards and industry of alloy tubes, annealed and tempered alloy tubes change the mechanical properties. Meet the required processing conditions. Its performance is higher than ordinary seamless steel pipe, chemical composition contains more Cr, so it has high temperature resistance, low temperature resistance and corrosion resistance. Common carbon seamless tube does not contain alloy components or contains a small amount of alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries, because the mechanical properties of alloy tubes are variable and easy to adjust.

Seamless steel pipe material is divided into: 10, 20, 35, 45, 40Mn2, 45Mn2, 27SiMn, 20Cr, 40Cr, 20CrMo, 35CrMo, 38CrMoA1, 50CrV, 30CrMnSi ASTM A500-98 these several.

Seamless steel pipe implementation standards:

1, the structure of seamless pipe (GB/T8162-2008) is used for general structure and mechanical structure of seamless steel pipe.

2, seamless steel pipe for fluid transport (GB/T8163-2008) is used for the transport of water, oil, gas and other fluids of the general seamless steel pipe.

3, low and medium pressure boiler seamless steel tube (GB3087-2008) is used to manufacture a variety of structures of low and medium pressure boiler superheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe and arch brick pipe of high quality carbon structural steel hot rolled and cold drawn (rolled) seamless steel tube.

4, high pressure boiler seamless steel tube (GB5310-2008) is used for the manufacture of high pressure and above pressure water tube boiler heating surface with high quality carbon steel, alloy steel and stainless heat resistant steel seamless steel tube.

5, chemical fertilizer equipment for high pressure seamless steel pipe (GB6479-2000) is suitable for the working temperature of -40~400℃, working pressure of 10~30Ma chemical equipment and pipeline of high quality carbon structural steel and alloy steel seamless steel pipe.

6, petroleum cracking seamless steel pipe (GB9948-2006) is suitable for petroleum refinery furnace tube, heat exchanger and pipeline seamless steel pipe.
Alloy steel pipe material according to the thickness, specifications can be divided into 12-42CrMO, T91, 30CrMo, 20G, 15CrMoV, Cr9Mo, 27SiMn, 10CrMo910, 15Mo3, 35CrMoV, 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 16Mn 12Cr1MoV, 50Cr, 15CrMo, 45CrNiMo, etc. Alloy steel pipe is made of carbon steel, stainless steel and alloy structural steel by cold rolling technology or hot rolling technology.
