Seamless steel yeeb nkab rau boilers yog ib hom boiler yeeb nkab thiab belongs rau qeb ntawm seamless steel kav. Txoj kev tsim khoom yog tib yam li seamless steel kav, tab sis muaj cov kev cai nruj rau hom hlau siv hauv kev tsim cov kav hlau. Seamless steel kav rau boilers feem ntau yog siv nyob rau hauv qhov kub thiab txias siab. Nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, cov kav dej 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. Seamless steel kav rau boilers yog siv los ua cov kav dej siab, cov kav dej loj, thiab lwm yam.
