Boiler tubes
Hot rolled stainless steel boiler pipes
We can supply more than 20 varieties of high, medium and low pressure boiler tubes and high alloy boiler tubes, and successfully rolled T91, SUP304H, and internally threaded boiler tubes.
- Low and medium pressure boiler tubes:
Implement GB3087 standard. Used for heating surface tubes of low and medium pressure boilers (with a working pressure generally not exceeding 5.88Mpa and a working temperature below 450 ℃).
- High pressure boiler tubes:
Implement relevant standards such as GB3087, GB5310, DIN17175, ASME SA-106, ASME SA-210M, ASME SA-213M, ASME SA-335M, etc. Used for heating surface tubes, economizers, superheaters, reheaters, petrochemical industry tubes, etc. of high-pressure boilers (working pressure generally above 9.8Mpa, working temperature between 450 ℃ and 650 ℃).
- Nuclear power pipes:
Implement GB5310, ASTM A106, and ASTM A335 standards. Used for conventional main steam pipelines and main feedwater pipelines.
