High-pressure Boiler Tubes Supplier
High-pressure boiler tubes: stainless steel seamless steel tubes for high-quality carbon structural steel, alloy structural steel and steam boiler pipes, mainly used for the manufacture of high pressure and high pressure. Usually under high temperature and high pressure, high temperature flue gas and water vapor in the tube will also oxidize and Corrosion, the steel tube has high durability, high oxidation resistance, and good structural stability.
Steel grade: high quality carbon structural steel No. 20G, a106b, a106c alloy structural steel No. 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12cr2mog , 12CR1MOVG, 12cr3movsitib, etc.; stainless steel commonly used 1cr18ni9, 1cr18ni11nb high-pressure boiler tube in addition to chemical composition and mechanical properties, but also to ensure the root of the hydraulic test, to be expanded, flattening test. The steel pipe is delivered under heat treatment conditions.
High-pressure boiler tube specifications and appearance quality: GB5310 "high-pressure boiler seamless steel pipe" hot-rolled pipe outer diameter 22 ~ 530mm, wall thickness 20 ~ 70mm. The cold (cold rolled) pipe diameter is 10~108mm, and the wall thickness ranges from 2.0 to 13.0mm.
1.The general boiler tube temperature is below 450 °C, and the domestic pipeline is mainly made of No. 10, No. 20 carbon steel hot rolled tube or cold drawn tube.
2.High-pressure boiler tubes are often under high temperature and high pressure conditions, and high temperature flue gas and water vapor in the pipeline will oxidize and corrode. The steel pipe is required to have high durability, high pressure corrosion resistant alloy high pressure boiler tube high pressure boiler tube, and has good structural stability.
How to use:
1.General boiler tubes are mainly used in the manufacture of water wall tubes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large, small pipes and arched brick pipes.
2.high pressure boiler tubes are mainly used to manufacture high pressure, super high pressure boiler superheater tubes, reheater tubes, conduits, main steam tubes, etc.
In addition, the microstructure, grain size and decarburization layer of the finished steel tube are required.
