Khoom nta:
Cov khoom muaj pes tsawg leeg: cov roj carbon cov hlau yog feem ntau muaj cov pa roj carbon ua ke, feem ntau muaj lwm cov khoom siv sib luag, feem ntau muaj lwm cov khoom siv sib khi me me xws li silicon, tus txiv neej, thiab phosphorus.
Lub zog: cov hlua roj carbon rau ntawm lawv lub zog siab, ua rau lawv haum rau cov kev siv uas yuav tsum muaj cov kabmob tseem ceeb siv cov khoom siv thiab kev ntsuas.
Corrosion Kuj: Thaum tsis yog corrosion-resistant li stainless hlau, carbon steel tubes muaj zoo corrosion, tshwj xeeb yog nyob hauv ib puag ncig qhuav.
Luam Ntawv: Cov pa roj carbon ntau yog yooj yim rau kev siv lub tshuab, txiav, thiab siv WELD, tso cai rau kev ua lag luam thiab xav tau raws li xav tau.
Tus nqi them ua haujlwm: Cov nqi tsim rau cov roj txheem hlau yog qhov tsis tshua muaj piv rau qee cov khoom siv hlau, ua rau lawv haum rau cov phiaj xwm siv nyiaj txiag.
