15Mo3 alloy pipe is generally used for heating surface pipe of low and medium pressure boiler (working pressure is generally not more than 5.88MPA, working temperature is below 450 ℃); it is used for heating surface pipe, economizer, superheater and reheat of high pressure boiler (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ and 650 ℃).

Common executive standards of 15Mo3:
GB / T8162 -- Chinese national standard
Gb5310 -- Chinese national standard
ASME SA210 - American boiler and pressure vessel code
ASME SA213 - American boiler and pressure vessel code
