Vuam yeeb nkab haum luj tshib, 90 Degree Stainless hlau luj tshib
Lub luj tshib yog cov yeeb nkab fittings uas hloov cov kev taw qhia ntawm cov kav dej hauv cov kav dej.Raws li lub kaum sab xis, muaj peb feem ntau siv: 45 ° thiab 90 ° 180 °.Tsis tas li ntawd, raws li kev xav tau ntawm engineering, nws kuj suav nrog lwm yam txawv txav lub luj tshib xws li 60 °.Cov ntaub ntawv luj tshib muaj xws li cam khwb cia hlau, stainless hlau, hlau alloy, forgeable cam khwb cia hlau, carbon steel, non-ferrous hlau thiab yas.Lub luj tshib yog cov yeeb nkab fittings uas hloov cov kev taw qhia ntawm cov kav dej hauv cov kav dej.Raws li lub kaum sab xis, muaj peb feem ntau siv: 45 ° thiab 90 ° 180 °.Tsis tas li ntawd, raws li kev xav tau ntawm engineering, nws kuj suav nrog lwm yam txawv txav lub luj tshib xws li 60 °.Cov ntaub ntawv luj tshib muaj xws li cam khwb cia hlau, stainless hlau, hlau alloy, forgeable cam khwb cia hlau, carbon steel, non-ferrous hlau thiab yas.Txoj hauv kev sib txuas nrog cov yeeb nkab yog: kev sib txuas ncaj qha (txoj kev feem ntau) flange kev twb kev txuas, kub yaj kev twb kev txuas, electrofusion kev twb kev txuas, threaded kev twb kev txuas thiab lub qhov (socket) kev twb kev txuas, thiab lwm yam. stamping luj tshib, kub nias lub luj tshib, thawb lub luj tshib, casting luj tshib, forging luj tshib, clip luj tshib, thiab lwm yam. Lwm lub npe: 90 ° luj tshib, txoj cai kaum khoov, hlub khoov, dawb steel luj tshib, thiab lwm yam.
Qhov sib txawv tseem ceeb ntawm stainless hlau luj tshib thiab carbon steel luj tshib yog qhov sib txawv ntawm cov khoom.Cov tshuaj muaj pes tsawg leeg muaj nyob rau hauv lub luj tshib yuav ua rau lub luj tshib ntawm lub luj tshib los ntawm xeb thiab corrosion mus ntev.
Raws li tus qauv tsim, nws tuaj yeem hloov mus rau hauv: 90 ° stainless hlau ntev vojvoog luj tshib
1. Raws li tus qauv tsim, nws tuaj yeem muab faib ua tus qauv hauv lub tebchaws, qauv nkoj, qauv hluav taws xob, dej qauv, Asmeskas tus qauv, tus qauv German, tus qauv Japanese, qauv Lavxias, thiab lwm yam.
2. Nws tuaj yeem muab faib ua kev thawb, nias, forging, casting, thiab lwm yam raws li txoj kev tsim khoom.
90 ° stainless hlau luj tshib yog siv los txuas cov yeeb nkab fittings nyob rau hauv pipeline installation, thiab yog siv rau kev sib txuas cov yeeb nkab khoov.Txuas ob lub kav dej nrog tib lub nominal diameters los ua 90 ° tig.
Stainless hlau luj tshib kuj tuaj yeem muab faib ua lub luj tshib sib npaug thiab tsis sib npaug ntawm lub luj tshib.Lub luj tshib sib npaug yog siv los txuas cov kav dej nrog tib txoj kab uas hla sab nraud, thiab lub luj tshib tsis sib npaug yog siv los txuas cov kav dej nrog cov kab sib txawv.
Stainless hlau feem ntau yog ua los ntawm kev ntxiv cov feem ntau ntawm Cr, Ni thiab lwm yam alloys raws li carbon steel, thiab cov ntsiab lus piv tau ncav cuag ntau tshaj 20%.Cov qib steel feem ntau yog: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9.Thawj tus naj npawb ntawm cov hlau uas sawv cev los ntawm cov lej yog Nyiv thiab Tebchaws Meskas tus lej tus lej sawv cev, thiab hom kawg (1Cr18Ni9Ti) yog cov qauv siv tus lej hauv tsev.Pitting corrosion ntawm stainless hlau feem ntau tshwm sim nyob rau hauv aqueous ib puag ncig uas muaj iodine, chlorine, thiab bromine.Yog vim li cas rau pitting corrosion ntawm stainless hlau yog hais tias chloride ions yog active anions, uas yog yooj yim adsorbed, squeezing tawm oxygen atoms, thiab reacts nrog cov cations nyob rau hauv lub passivation zaj duab xis los tsim soluble chlorides, rhuav tshem cov passivation zaj duab xis, tsim me pores, thiab dhau los ua qhov inducement theem ntawm pitting corrosion.Nyob rau theem no, ib qho thaiv Circuit Court yog tsim, thiab tam sim no corrosion tshwm sim.
9 Cov ntsiab lus ntawm kev paub txog stainless hlau luj tshib kho
Stainless hlau lub luj tshib lub hom phiaj: txhawm rau txuas ob lub kav dej nrog tib lub nominal txoj kab uas hla kom tig 90-degree.
1. Faib carbon steel, cam khwb cia hlau, hlau alloy, stainless hlau, tooj liab, aluminium alloy, yas, argon leaching, ppc, thiab lwm yam los ntawm cov khoom siv.
2. Raws li txoj kev tsim khoom, nws tuaj yeem muab faib ua kev thawb, nias, forging, casting, thiab lwm yam.
3. Raws li cov qauv tsim, nws tuaj yeem muab faib ua tus qauv hauv lub tebchaws, tus qauv hluav taws xob, tus qauv dej, tus qauv Asmeskas, tus qauv German, tus qauv Japanese, tus qauv Lavxias, thiab lwm yam. Stainless hlau kuj yog ib qho ntawm cov khoom siv zoo tshaj plaws hauv cov khoom siv hlau.Vim tias cov hlau tsis muaj steel muaj qhov ua haujlwm zoo corrosive, yog li nws tuaj yeem ua rau cov khoom siv ruaj khov ruaj khov ntawm kev tsim engineering.Chromium-muaj stainless hlau kuj sib txuas cov neeg kho tshuab lub zog thiab siab extensibility, yooj yim rau txheej txheem thiab tsim cov khoom, thiab tuaj yeem ua tau raws li qhov kev thov.
