** 1. Yog cov roj carbon steel pheej yig? **
Yog lawm, cov roj hlau tsawg heev yog feem ntau xav tias pheej yig. Nws yog ib qho ntawm feem ntau dav thiab siv hlau vim tias nws tus nqi qis, qauv ducle, thiab yooj yim ntawm cov fabrication. Nws cov tshuaj lom neeg sib xyaw ua ke thiab cov huab cua ntau lawm ua rau nws muaj nyiaj txiag ntau heev piv rau feem ntau lwm cov hlau thiab alloys.
** 2. Dab tsi yog cov yeeb nkab kim tshaj plaws? **
Cov khoom siv cov yeeb yam kim tshaj plaws feem ntau tshwj xeeb siab -}} performance performance performance performances performanceoys. Ntawm cov no, nickel - bued supallots xws li ** Hastelloy ** lossis ** Inconel ** feem ntau yog tus nqi ntau tshaj plaws. Cov ntaub ntawv no tsis tshua muaj nqi thiab lawv cov kev tiv thaiv ntau yam kub, ua rau lawv muaj kev lag luam zoo, ua rau lawv muaj tshuaj lom neeg ua haujlwm, thiab roj offshore thiab roj kev lag luam thiab roj av.
** 3. Puas dub yeeb cov dej cawv? **
Yog lawm, cov yeeb nkab dub tsis xeb. Cov xim dub "los ntawm ib lub zeb - teev txheej ntawm cov hlau oxide tsim thaum lub sijhawm tsim khoom, uas muaj tsuas yog kev tiv thaiv tsawg. Cov nplai no tuaj yeem flake tawm, thiab cov hlau liab qab hauv qab yog qhov muaj txiaj ntsig zoo rau xeb thaum muaj dej noo thiab oxygen. Nws tsis yog tsim los rau cov chaw muaj kev tiv thaiv ib puag ncig tsis muaj kev tiv thaiv ntxiv zoo li cov xim pleev xim lossis pleev xim.
** 4. Ntev npaum li cas dub steel yeeb nkab kawg? **
Lub neej ntawm cov yeeb nkab steel dub nyob ntawm nws ib puag ncig. Nyob sab hauv tsev, nyob rau hauv qhov chaw qhuav (zoo li rau cov kab roj sab hauv ib lub tsev), nws tuaj yeem siv sijhawm ntev txog xyoo,, nws yeej muaj lub neej ntawm cov qauv. Tawm sab nraum zoov lossis nyob rau sab nraud sab nraud lossis cov mob corrosive, nws tuaj yeem pib ua kom pom muaj xeb tsawg dua li ib xyoos thiab tej zaum yuav tsis muaj ntau xyoo tsis muaj kev tiv thaiv.
** 5. Puas muaj cov pa yeeb nkab xeb? **
Yog lawm, cov yeeb nkab steel yog qhov ua rau xeb kom xeb (corrosion). Xeb yog oxidation ntawm hlau, uas yog thawj feem ntawm cov roj carbon hlau. Tsis zoo li cov hlau stainless, carbon hlau tsis muaj qhov tseem ceeb ntawm chromium los tsim passive txheej. Yog li ntawd, nws yuav xeb thaum raug huab cua thiab noo noo tshwj tsis yog muaj kev tiv thaiv nrog cov txheej txheej, pleev xim, lossis lwm hom ntawm corrosion inhibition.
