Boiler raj yog qhib rau ntawm ob qho kawg thiab muaj qhov hollow seem, qhov ntev thiab ib puag ncig ntawm cov hlau loj, raws li cov txheej txheem tsim khoom tuaj yeem muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab, steel yeeb nkab specification nrog tag nrho qhov ntev (xws li txoj kab uas hla lossis ntev) thiab phab ntsa tuab, hais tias nws qhov loj me yog qhov dav heev, los ntawm txoj kab uas hla me me mus txog rau ob peb meters hauv txoj kab uas hla, txoj kab uas hla loj.

Cov raj hlau siv tau rau cov kav dej, cov khoom siv thermal, kev lag luam machinery, roj av geological tshawb fawb, ntim, tshuaj lom neeg kev lag luam thiab cov hom phiaj tshwj xeeb.

(1) High quality carbon structural steel hlau 20G, 20MnG, 25MnG.

(2) Alloy qauv steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, thiab lwm yam.
