| Kev sib kis los ntawm lubricants siv hauv kev sib khi | Lubricants tuaj yeem kis kab mob hauv cov kav dej, ua rau muaj kev pheej hmoo. |
| Tsis tsim nyog rau kev siv high-pressure | Threaded fittings tsis pom zoo rau cov tshuab ua haujlwm siab. |
| Tsis pom zoo nyob rau hauv corrosive thiab erosive ib puag ncig los yog cyclic loading | ASME B31.3 tawm tswv yim tawm tsam lawv cov kev siv hauv cov xwm txheej no. |
Cov kev tsis zoo no qhia txog qhov tseem ceeb ntawm kev xaiv txoj cai haum rau daim ntawv thov. Piv txwv li, kuv tsis txhob siv threaded fittings nyob rau hauv high-pressure los yog corrosive ib puag ncig, raws li lawv cov kev ua tau zoo tej zaum yuav tsis ua raws li cov qauv kev nyab xeeb. Cov txheej txheem kev teeb tsa kom raug, xws li zam dhau kev nruj, tuaj yeem txo qee qhov teeb meem no.
Los ntawm kev nkag siab txog qhov muaj zog thiab qhov tsis muaj zog ntawm cov khoom siv zoo tib yam threaded yeeb nkab fittings, kuv tuaj yeem txiav txim siab kom paub meej tias kev ua haujlwm zoo thiab kev nyab xeeb.
Yuav ua li cas xaiv txoj cai Threaded yeeb nkab haum
Xaiv txoj cai threaded yeeb nkab haum yuav tsum tau ua tib zoo xav txog ntau yam. Txhua qhov kev txiav txim siab cuam tshuam rau lub cev kev ua haujlwm, ua haujlwm ntev, thiab kev nyab xeeb. Hauv qab no, kuv yuav qhia koj txog cov ntsiab lus tseem ceeb los ntsuas.
Xav txog Pipe Material Compatibility
Cov khoom siv ntawm lub fittings yuav tsum sib haum nrog cov yeeb nkab thiab cov kua dej uas nws yuav nqa. Piv txwv li, stainless hlau resists corrosion nyob rau hauv dej systems, thaum tooj dag ua tau zoo nyob rau hauv nruab nrab-kub daim ntaub ntawv. Kuv ib txwm pom zoo xaiv cov ntaub ntawv uas tiv thaiv kev degradation los ntawm ib puag ncig yam xws li av noo lossis tshuaj lom neeg.
Tswv yim: Siv cov fittings ua los ntawm malleable cam khwb cia hlau rau cov kav dej dav dav, raws li lawv ua tau raws li cov qauv zoo li BS EN 10242 thiab ISO 49: 1994 rau kev ua haujlwm ntev thiab kev ua haujlwm.
Ntsuas cov kev xav tau siab thiab kub
Threaded fittings yuav tsum tiv taus lub siab tshaj plaws thiab kub. Rau cov kev xav tau, kuv tso siab rau cov ntaub ntawv ua haujlwm kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
| Txuj | Kev piav qhia |
|---|---|
| TS EN 10242 EN 10242 | Tsim thiab kev ua tau zoo yuav tsum tau rau malleable cam khwb cia hlau. |
| TS EN ISO 49: 1994 | International standard rau siab/kub ntsuas. |
Piv txwv li, tooj dag fittings kov kub txog li 80 ° C, thaum cov ntawv siv chav yuav tsum tau fittings ntsuas rau 10 bar ntawm 180 ° C. Nco ntsoov sab laj PT kab kos los kho qhov ntsuas siab rau kev hloov pauv kub.
Xaiv qhov raug xov hom thiab qhov loj me
Xov hom thiab qhov loj me yog qhov tseem ceeb rau kev sib txuas ruaj ntseg. NPT threads, nrog rau lawv cov qauv tapered, xyuas kom nruj sealing. Sizing kab kos pab phim fittings rau cov yeeb nkab qhov ntev, tsis txhob xau los yog misalignment.
| Xov Hom | Loj | Txiv neej txoj kab uas hla (mm) | Poj niam txoj kab uas hla (mm) |
|---|---|---|---|
| BSP | 1/8 " | 9,73mm ua | 9.05mm ib |
| BSP | 1/4 " | 13.16 mm | 12.1 hli |
| NPT | 1/8 " | 9,73mm ua | 9.25mm ib |
| NPT | 1/4 " | 13.46mm 3 | 12.85mm 3 |
Nco tseg: BSP threads muaj lub kaum sab xis 55 °, thaum NPT threads muaj 60 ° taper. Xaiv raws li koj qhov system cov cai.
Soj ntsuam daim ntawv thov ib puag ncig (xws li, Sab Hauv Tsev vs. Sab nraum zoov)
Ib puag ncig yam xws li kub hloov pauv, UV raug, thiab cov av noo cuam tshuam rau kev ua tau zoo. Rau cov tshuab sab nraum zoov, kuv nyiam cov ntaub ntawv tiv thaiv corrosion xws li galvanized steel lossis stainless hlau. Cov tshuab sab hauv tsev feem ntau tso cai rau cov khoom siv tau yooj yim dua, xws li siv tooj dag lossis PVC.
Los ntawm kev ntsuam xyuas cov xwm txheej no, koj tuaj yeem xaiv cov yeeb nkab fittings uas ua kom muaj kev ntseeg siab, kev nyab xeeb, thiab kev ua haujlwm zoo hauv koj lub cev.
Ordinary threaded yeeb nkab fittings ua haujlwm tseem ceeb hauv cov kav dej thiab kev lag luam. Lawv versatility thiab kev cia siab rau ua rau lawv indispensable nyob rau hauv ntau yam kev siv, los ntawm cov kav dej nyob rau hauv cov roj pipelines. Kuv ib txwm pom zoo kom ntsuas koj qhov system cov cai tshwj xeeb ua ntej xaiv fittings. Qhov no ua kom pom kev ua haujlwm zoo, kev nyab xeeb, thiab kav ntev hauv txhua qhov haujlwm.
FAQ
