Boiler Tubes Application

Generally, the common boiler tub is used in a temperature below 350 °C, and the Chinese boiler tube material mainly uses #10, #20, 20G, 20MnG, alloy structural steel No. 15MoG, 20MoG, 12Cr1MoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB. Use carbon steel hot rolled tube or cold drawn tube manufacturing.
High-pressure boiler tubes are often subjected to high temperature and high pressure conditions, and the tubes may oxidize and corrode under the action of high temperature flue gas and water vapor. Steel pipes are required to have high durability, high corrosion resistance and good structural stability.

Boiler Steel Tubes Application 

General boiler tubes are mainly used to manufacture water-cooled wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arch brick pipes.
High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam tubes, etc. for high-pressure and ultra-high pressure boilers. The supply and demand trend of the high-pressure boiler tube industry is generally stable, but the supply and demand situation of each specific sub-sector will be further differentiated. Insiders pointed out that the most critical link is the use and promotion of new energy-saving insulation 20g high-pressure boiler tube equipment.
