Introduction of the European and Japanese standard boiler tubes
Boiler tube is mainly used in the manufacture of super heater, re-heater, water cooled wall and economizer etc. for supercritical and ultra-supercritical boiler. Tubes are required have high rupture strength, high oxidation corrosion resistance, and have good organizational stability.

Product features
Boiler tube is used frequently in the condition of high temperature and high pressure. Under the action of high temperature flue gas and water vapor, oxidation and corrosion will happen to tubes. So the boiler steel tubes with high rupture strength, high oxidation corrosion resistance, and have good organizational stability.
