The Main Material of Alloy Pipe

Shannxi Shew-E Steel Pipe Co.,Ltd | Updated: Apr 11, 2017

The main material of alloy pipe

Alloy tube is a kind of seamless steel pipe, but its high temperature, low temperature resistance, corrosion resistance is higher than the average seamless steel pipe, because of it contains more Cr, so the alloy tube in the oil, Electricity, boilers and other industries pay a wide range of applications.

It's generally used for low or medium pressure boiler(Working pressure ≦ 5.88mpa, working temperature ≦ 450 ℃)of the heating surface tube; for high pressure boiler (working pressure ≧ 9.8mpa, operating temperature between 450℃-650 ℃) of the heating surface tube, the province Coal, superheater, reheater, petrochemical industry pipe.


The main material:12Cr1MoV、P22(10CrMo910)、T91、P91、P9、T9、WB36、Cr5Mo(P5、STFA25、T5、)、 15CrMo(P11、P12、STFA22) 13CrMo44;

Implementing standards:DIN17175-79、JISG3467-88、JISG3458-88、GB5310-95 、GB9948-88、ASTMA335/A335m、ASTMA213/A213m;

For example,GB5310-1995(High pressure boiler seamless steel pipe) , mainly used for high temperature resistant and high pressure transmission fluid collection box and the pipeline in power plant and nuclear power plant boiler. The typical materials includes 20G、12Cr1MoVG、15CrMoG and ect.
