High pressure boiler tubes are used in high
temperature and high pressure conditions. Steel tubes are subject to oxidation
and corrosion under the action of high temperature flue gas and water vapor.
The steel tube is required to have high lasting strength, high oxidation
resistance corrosion performance and good stability.
Application:
Used for manufacturing
superheated pipelines, the steam pipe, boiling water tube, flue tube, small
flue tube, etc.of low, mediam pressure boiler, the general industry boiler
