    Daim ntawv thov

    Nws yog tsuas yog siv los ua cov pa roj carbon zoo steel, alloy steel qauv thiab stainless hlau kub-resistant steel seamless steel kav rau kev kub siab thiab siab dua chav boiler kav.

    Feem ntau yog siv rau kev kub siab thiab kub kev pab cuam ntawm boiler (Superheater raj, reheater raj, cua qhia raj, lub ntsiab chav tub raj rau siab thiab ultra siab siab boilers). Nyob rau hauv qhov kev txiav txim ntawm kub flue roj thiab dej vapor, lub raj yuav oxidize thiab corrode. Nws yuav tsum tau hais tias cov yeeb nkab steel muaj cov kav ntev, siab tiv thaiv oxidation thiab corrosion, thiab cov qauv zoo.
