Rau ib xyoo pua, hlau tau tsav lag luam kev loj hlob, paving txoj kev rau kev nce qib hla ntau cov haujlwm. Cov lus ntawm cov hlau txuas rau hauv lub siab ntawm Hose kawg fittings, ib qho tseem ceeb hauv kev sib tw hose uas tau ua rau kom muaj kev xav tau. Tab sis koj puas paub, nyob hauv lub ntiaj teb Hose cov rooj sib txoos, tshwj xeeb tshaj yog nyob rau hauv cov tshuab hydraulic, kev xaiv ntawm cov hlau tuaj yeem ua rau lub ntiaj teb sib txawv?
Thaum cov ntaub ntawv zoo li tooj dag thiab txhuas muaj lawv siv, hlau, nyob rau hauv nws ntau cov ntaub ntawv, feem ntau yog lub hauv ntej-khiav rau hose kawg fittings. Qhov kev txiav txim siab ntawm kev siv carbon steel lossis stainless hlau yog ntau tshaj li kev xaiv; Nws yog hais txog kev nkag siab qhov xav tau koj lub rooj sib txoos hose hose yuav fim. Yam zoo li lub cev nqaij daim tawv, raug nqi, thiab muaj kev ua si muaj txiaj ntsig zoo hauv txoj kev txiav txim siab no. Tab sis tsis txhob txhawj xeeb, koj tsis tas yuav yog tus kws tshaj lij kom nkag siab txog qhov no. Kuv nyob ntawm no mus taug kev koj los ntawm cov ntaub ntawv tseem ceeb hais txog cov qauv hlau no, ua rau koj qhov kev txiav txim siab yooj yim dua. Cia peb ntsaub mus rau hauv cov hlau sib txawv ntawm cov hlau thiab tshawb pom tias yuav xaiv txoj cai thiab durability ntawm koj cov kev sibthodly detblies.
Carbon Steel, feem ntau ua los ntawm kev sib tov ntawm hlau thiab carbon, yog cov khoom siv hauv cov khoom siv hauv kev tsim khoom. Nws muaj pes tsawg leeg sib txawv, nrog cov ntsiab lus roj carbon ntau dua los ntawm qis li 0.3% mus rau ntau dua 2%. Qhov no hloov pauv ua rau cov qib sib txawv ntawm cov roj carbon hlau, txhua tus muaj cov khoom sib txawv. Qhov ntau dua cov ntsiab lus carbon, ntau dua cov hlau ua kom tiav, tab sis nws kuj nce nws cov brittleness. Tshwj xeeb, carbon hlau tsis muaj cov chromium stip tam sim no nyob rau hauv stainless hlau, uas yog qhov tseem ceeb hauv corrosion tsis kam.
Nyob rau hauv lub realm ntawm hose kawg fittings, carbon steel yog ib qho kev xaiv nrov. Nws cov xwm muaj zog ua rau nws haum rau cov tshuab hydraulic, qhov kev kub siab yog ib qho kev cai. Cov pa roj carbon fittings feem ntau yog siv nyob rau hauv cov chaw muaj kev txhawj xeeb, tshwj xeeb yog qhov tsis muaj kev txhawj xeeb ntawm kev xeb lossis qhov chaw ib puag ncig yog tswj hwm. Lub zog ntawm cov pa roj carbon ntau yog tshwj xeeb rau hauv kev tswj hwm siab surges hauv hoses hydraulic.
Muaj feem ntau peb pawg ntawm cov roj carbon hlau: qis, nruab nrab, thiab siab. Txhua qeb yog haum rau ntau hom kev siv:
L Tsawg cov roj carbon hlau (hlau me) : siv hauv cov chaw xav tau tsawg. Nws yooj yim dua rau cov duab thiab weld tab sis ib txwm muaj xeb yam tsis muaj kev tiv thaiv tiv thaiv.
L Nruab Nrab Cov Hlau Steel : Muaj kev sib npaug zoo ntawm lub zog thiab ductility, ua kom nws haum rau ntau qhov chaw.
l Ligh carbon hlau : paub rau nws lub zog siab, nws tau siv hauv kev siv ntxhov siab qib siab tab sis tuaj yeem tawg.
Pros :
1. Cov kev ruaj khov : Tshwj xeeb cov pa roj carbon hlau, sawv ua haujlwm zoo rau lub cev nyhav.
2. Nqi-siv tau : Feem ntau tsis tshua kim tshaj qhov stainless hlau, ua rau nws xaiv tus nqi-txuag rau cov phiaj xwm siv nyiaj txiag-ristic.
3. Tshav kub kom ntev : Muaj peev xwm nrog nrog kev kub siab uas tsis muaj kev tsim qauv.
Cons :
1. Corrosion Speev : Tsis muaj kev tiv thaiv kev tiv thaiv lossis kev kho mob, cov hlau carbon tuaj yeem xeb thiab corrode, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig.
2. Cov ntawv thov tsawg : tsis tsim nyog rau ib puag ncig uas muaj dej noo siab lossis cov tshuaj uas muaj kev sib xyaw.
3. Brittleness : Muaj cov pa roj carbon ntau, thaum muaj zog, tuaj yeem tawg, uas tej zaum yuav muaj kev txhawj xeeb hauv qee cov ntawv thov.
Nyob rau hauv cov ntsiab lus teb ntawm Hose kawg fittings, xaiv cov hlau roj carbon yuav tsum sib thooj nrog cov cai tshwj xeeb, xav txog cov khoom siv thiab kev txwv ntawm cov khoom siv. Nkag siab txog cov khoom muaj zog thiab haum cov pa roj carbon hlau hauv ntau cov ntawv thov hydraulic thiab kev lag luam yog qhov tseem ceeb rau kev txiav txim siab paub. Kev paub txog cov muaj pes tsawg leeg, ntau yam, thiab cov tswv yim tswv yim ntawm cov hlau tuaj yeem coj koj hauv kev xaiv cov ntaub ntawv haum rau koj cov kev xav tau. Seb nws yog lub siab siab cov kab ke hydraulic lossis tshuaj tswj chaw teeb tsa, carbon steel tuaj yeem muab cov kab hlau ua kom ruaj khov thiab tau txais txiaj ntsig zoo.
Cov hlau stainless, cov khoom muaj txiaj ntsig nyob rau hauv hose kawg fittings, yog qhov txawv los ntawm nws cov ntsiab lus chromium tseem ceeb - tsawg kawg 10%. Qhov no chromium inclusions yog qhov tseem ceeb rau nws zoo-paub corrosion tsis kam. Tsis tas li ntawd, cov ntsiab xws li npib tsib xee, molybdenum, thiab nitrogen tuaj yeem ntxiv rau txhim kho cov khoom tshwj xeeb. Muaj ntau tshaj 150 qib ntawm stainless hlau, tab sis tsuas yog ob peb feem ntau yog siv nyob rau hauv hose fittings.
