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 has 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 Alloy Seamless Steel Tube 、20G Alloy Seamless Boiler Pipe、 15CrMo Seamless Alloy Steel Tube、16Mo3 Alloy Seamless Steel Pipe；
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.
