GB 5310- 2008 standard seamless tubes is applicable to making steam boiler, high-pressure and ultra-high pressure boiler, super heater tubes , reheater tubes, windpipe, main steam pipe system.  

High pressure boiler pipe is one of seamless steel pipe category. The method of manufacturing seamless pipes is same, but there are strict requirements in manufacturing of boiler tube. High pressure boiler tubes are usually used in high temperature and high pressure conditions, under the condition of high temperature flue gas and water vapor it will occur oxidation and corrosion. So the pipe should have following characteristics: high strength, high resistance to oxidation corrosion, good metallurgical structure, stability.

12Cr2MoG alloy steel pipes are use for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, working temperature below 450 ℃) and high-pressure boiler (working pressure is generally more than 9.8Mpa, working temperature of 450 ℃ -650between ℃) and economizer, super heater, re-heater, petrochemical industrial tubes.
