China High quality 7mm Steel Pipe Manufacturer – High pressure Boiler Seamless Steel Pipe – Future Metal
China High quality 7mm Steel Pipe Manufacturer – High pressure Boiler Seamless Steel Pipe – Future Metal Detail:
High-pressure boiler tube is a kind of boiler tube, which belongs to the category of seamless steel tube. The manufacturing method is the same as the seamless tube high pressure boiler tube, but there are strict requirements on the steel grade used to manufacture the steel tube. High-pressure boiler tubes are often in high-temperature and high-pressure conditions when used. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. for high-pressure and ultra-high-pressure boilers.
As the boiler tube works under high temperature and high pressure for a long time, the material will creep, the plasticity and toughness will decrease, the original structure will change, and corrosion will occur. Steel pipes used as boilers should have: (1) Sufficient permanent strength; (2) Sufficient plastic deformation ability; (3) Minimal aging tendency and hot brittleness; (4) High resistance to oxidation, coal ash and natural gas Corrosion, steam and stress corrosion performance at high temperature; (5) Good structure stability and good process performance. The steel grades of high-pressure boiler tubes include carbon steel and pearlite, ferrite and austenitic stainless heat-resistant steels.
According to the material classification, it can be divided into 20G high pressure boiler tube, 12Cr1MoVG high pressure boiler tube, Gangyan 102 high pressure boiler tube, 15CrMoG high pressure boiler tube, 5310 high pressure boiler tube, 3087 low and medium pressure boiler tube, 40Cr high pressure boiler tube, 1Cr5Mo high pressure boiler tube , 42CrMo high pressure boiler tube.
