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.

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.
The high pressure boiler tubes are mainly applied on the super heaters, reheaters, water walls, economizers of the super critical and ultra super critical boilers. And are required to have high creep rupture strength, high anti-oxidation corrosion resistance, and stable microstructures.
The main code or grade of the ASME high pressure boiler tubes:
SA-179M、SA-192M、SA-209M T1a、SA-210M Gr.C、SA-210M Gr.A1、SA-213M T11、SA-213M T12、SA-213M T22、SA-213M T23、SA-213M T91
SA-192/SA-192M Seamless Carbon Steel Boiler Tubes for High-Pressure Service
SA-210/SA-210M Seamless Medium-Carbon Steel Boiler and Superheater Tubes
The high pressure boiler tubes are often working in the condition with high pressure, high temperature and the interaction of the high temperature flue gas and vapor, which may lead to oxidation and corrosion on the tubes. So, the high pressure boiler tubes are required to have high creep rupture properties, high anti-oxidation corrosion and stable microstructure.
