Peb nthuav dav cov ntsiab lus tseem ceeb ntawm ob cov ntaub ntawv (me me hlau lossis stainless hlau) hauv qab no.Stainless hlau yog qhov ruaj khov dua nyob rau hauv cov dej qab ntsev thiab tuaj yeem siv rau hauv kev lag luam khoom noj khoom haus, thaum cov hlau me me muaj zog dua thiab tuaj yeem ua rau muaj zog ntau dua rau cov cab cab.

hlau me me:
Cov hlau me me, tseem hu ua carbon steel, yog ntau hom hlau hauv txhua daim ntawv thov, thiab hose clamps tsis muaj qhov tshwj xeeb.Nws kuj yog ib qho ntawm cov qib siab tshaj plaws ntawm cov hlau npog ntau yam ntawm cov khoom siv kho tshuab.Qhov no txhais tau hais tias kev nkag siab thiab qhia qhov tseeb qib tuaj yeem cuam tshuam loj rau kev ua haujlwm ntawm cov khoom tiav.Piv txwv li, cov kev ntxhov siab thiab cov kev xav tau ntawm cov ntawv hlau uas tsim cov tsheb lub cev yog qhov sib txawv ntawm cov khoom siv hose entrainment.Qhov tseeb, qhov zoo tagnrho hose clamp cov khoom specification tsis yog tib yam li lub plhaub thiab cov hlua.

Ib qho tsis zoo ntawm cov hlau me me yog tias nws muaj qhov tsis tshua muaj corrosion kuj.Qhov no tuaj yeem kov yeej los ntawm kev siv txheej txheej, feem ntau yog zinc.Qhov sib txawv ntawm txheej txheej thiab cov qauv txhais tau hais tias kev tiv thaiv corrosion tuaj yeem yog ib qho chaw uas hose clamps sib txawv heev.British Standard rau hose clamps yuav tsum tau 48 teev ntawm kev tiv thaiv kom pom liab xeb nyob rau hauv ib tug 5% nruab nrab ntsev tsuag tshuaj ntsuam, thiab ntau unmarked kite khoom tsis ua raws li qhov yuav tsum tau.

Stainless hlau:
Stainless hlau yog qhov nyuaj dua li cov hlau me me hauv ntau txoj hauv kev, tshwj xeeb tshaj yog thaum nws los txog rau hose clamps, raws li cov tuam txhab tsim nqi feem ntau siv cov khoom sib txawv los muab cov khoom lag luam nrog cov nqi tsim khoom qis thiab txo kev ua haujlwm.

Ntau lub hose clamp manufacturers siv ferritic stainless hlau ua lwm txoj rau cov hlau me me los yog cov nqi qis rau austenitic stainless hlau.Vim muaj chromium nyob rau hauv cov hlau alloy, ferritic steels (siv nyob rau hauv W2 thiab W3 qib, nyob rau hauv lub 400-qib series) tsis xav tau ib yam dab tsi ntxiv ua rau corrosion kuj.Txawm li cas los xij, qhov tsis muaj lossis tsis tshua muaj cov ntsiab lus nickel ntawm cov hlau no txhais tau hais tias nws cov khoom muaj ntau txoj hauv kev tsis zoo rau austenitic stainless hlau.

Austenitic stainless hlau muaj qib siab tshaj plaws ntawm kev tiv thaiv corrosion rau txhua hom kev xeb, nrog rau cov kua qaub, muaj qhov dav tshaj plaws ntawm kev ua haujlwm kub, thiab tsis yog hlau nplaum.Feem ntau 304 thiab 316 qib stainless hlau clips muaj;ob qho tib si cov ntaub ntawv siv tau rau kev siv dej hiav txwv thiab Lloyd's Register pom zoo, thaum qib ferritic tsis tuaj yeem.Cov qib no tseem tuaj yeem siv rau hauv kev lag luam khoom noj thiab dej haus, qhov twg cov kua qaub xws li acetic, citric, malic, lactic thiab tartaric acids yuav tsis tso cai siv cov hlau ferritic.
