High-pressure boiler raj yog ib hom boiler raj thiab belongs rau qeb ntawm seamless steel raj. Txoj kev tsim khoom yog tib yam li cov kav dej seamless, tab sis muaj cov kev cai nruj rau hom hlau siv hauv kev tsim cov kav hlau. High-pressure boiler raj feem ntau raug rau qhov kub thiab txias siab thaum siv. Nyob rau hauv qhov kev txiav txim ntawm high-temperature flue gas thiab dej vapor, cov hlab yuav oxidize thiab corrode. Cov kav hlau steel yuav tsum muaj lub zog ntev ntev, ua haujlwm siab rau oxidation thiab corrosion, thiab zoo structural stability. High-pressure boiler raj yog tsuas yog siv los tsim superheater raj, reheater raj, cua qhia raj, lub ntsiab chav boilers, thiab lwm yam.
