Peb lub tuam txhab yog ib tug kws tshaj lij thiab txhim khu kev qha ib-nres kev pab cuam chaw tsim tshuaj paus lwm tus neeg exporters. Peb tsis tsuas yog muab cov kav dej, raj, phaj, ntawv, fittings, flanges, fasteners, tab sis kujfabricated yeeb nkab spoolskev pabcuam.
Hom Flanges Hauv Piping
Hom flange yuav siv tau rau daim ntawv thov piping nyob ntawm, feem ntau, ntawm qhov xav tau lub zog rau flanged sib koom. Flanges yog siv, hloov mus rau welded kev sib txuas, los pab tswj kev ua haujlwm (ib flanged sib koom tuaj yeem tshem tau sai thiab yooj yim). Dab tsi yog hom flanges feem ntau siv hauv cov kav dej? Cov hom flanges tseem ceeb yog lub caj dab vuam, lub caj dab ntev vuam, plam-rau, qhov (socket weld), lap joint, threaded thiab dig muag flanges.
Weld Neck Flange (WNFF, WNRF, WNRJ)
Weld caj dab flange tseem hu ua lub caj dab siab flange lossis tapered hub flange. Lub caj dab weld flange muaj lub caj dab uas tuaj yeem hloov cov yeeb nkab kom nruj. Nws kuj tseem pab txo qhov siab sib sau ua ke hauv qab ntawm flange. Nws yog sib xws nrog cov kav dej uas ua haujlwm ntawm qhov qis lossis siab kub thiab tiv taus siab.
Qhov (socket) Weld Flanges (SWRF)
Lub qhov (socket) weld flanges yog txuas rau sab nraud tsuas yog los ntawm lub qhov (fillet weld). Nws feem ntau tsis pom zoo rau cov kev pabcuam tseem ceeb. Cov no muaj txiaj ntsig zoo rau cov kab me me hauv koj lub cev. Lub zog zoo li qub yog sib npaug rau plam-ntawm flanges, tab sis lub zog qaug zog yog 50 feem pua siab dua ob-welded slip-on flanges. Feem ntau siv los ua lwm txoj hauv kev weld caj dab thaum qhov chaw yog qhov txwv.
Slip-on Flange (SORF)
Lub plam-on flange yog lub nplhaib (nrog lossis tsis muaj lub hub) tso rau ntawm cov yeeb nkab kawg. Lub ntsej muag flange txuas los ntawm qhov kawg ntawm cov yeeb nkab los ntawm qhov kev ncua deb txaus los thov cov hlaws welded mus rau sab hauv txoj kab uas hla. Raws li lub npe qhia, cov flanges plam hla lub yeeb nkab thiab hu ua slip-on flanges.
Lap Joint Flanges
Lap Joint flanges muaj txiaj ntsig zoo nrog qhov xaus thaum cov yeeb nkab ua los ntawm cov khoom kim heev. Piv txwv li, cov pa roj carbon steel flange tuaj yeem muab ntxiv rau hauv cov yeeb nkab stainless hlau vim tias cov flanges tsis tuaj yeem cuam tshuam nrog cov khoom hauv cov yeeb nkab.
Qhov muag tsis pom Flanges
Kev tsim cov qhov muag tsis pom flanges tshwm sim yam tsis muaj qhov bore thiab yog siv los ua kom tsis muaj qhov kawg ntawm lub nkoj siab qhib, li qub, thiab cov kav dej. Yog tias koj saib los ntawm qhov pom ntawm qhov ntsia hlau thauj khoom thiab lub siab sab hauv, feem ntau cov flange overstressed yog qhov muag tsis pom flanges uas loj dua.
Threaded Flanges
Threaded flanges zoo ib yam rau slip-on flanges, tab sis qhov sib txawv tseem ceeb yog tias threaded flange yog dhuav tawm kom haum rau hauv txoj kab uas hla ntawm cov yeeb nkab tshwj xeeb. Threaded flange yog ib hom flange uas muaj taper yeeb nkab threads nyob rau hauv nws bore conforming rau ASME B1.20.1 thiab pab tau nyob rau hauv piping systems.
Cov khoom siv los tsim Flanges
Cov yeeb nkab flanges tuaj yeem tsim los ntawm ntau cov ntaub ntawv sib txawv uas nyob ntawm cov khoom siv thiab cov kev xav tau ntawm daim ntawv thov. Kev xaiv yog nyob ntawm cov yam ntxwv xws li kev lag luam, ntws siab, kev khiav hauj lwm kub, thiab ib puag ncig corrosion. Qee cov khoom siv feem ntau suav nrog cov hauv qab no:
Cov pa roj carbon steel
Nws yog steel alloyed feem ntau nrog carbon. Lub zog siab thiab hardness nce nrog cov ntsiab lus carbon, qis melting point, thiab ductility. Qhov no yog qib khoom siv tshaj plaws.
Hlau alloy
Nws yog steel alloyed nrog ib lossis ntau lub ntsiab lus uas hloov lossis txhim kho cov khoom ntawm cov hlau. Cov alloys muaj xws li chromium, molybdenum, nickel, vanadium, thiab manganese.
Stainless hlau
Nws yog hlau alloyed nrog chromium nyob rau hauv cov nyiaj saum toj no 10%. Chromium ua rau cov hlau tsis muaj steel muaj kev tiv thaiv corrosion ntau dua li cov hlau uas xeb tau yooj yim los ntawm huab cua thiab ya raws.
Aluminium
Nws yog qhov tsawg-ceev, ductile, thiab malleable hlau nrog nruab nrab lub zog. Nws muaj kev tiv thaiv corrosion zoo dua piv rau lwm yam alloy thiab carbon hlau. Nws yog qhov tseem ceeb tshaj plaws thaum siv flange uas yuav tsum muaj qhov hnyav thiab lub zog.
Cam khwb cia hlau
Hlau thaum nws yog alloyed nrog silicon, carbon, thiab ntau lwm yam alloys ua cam khwb cia hlau. Silicon rog carbon tawm ntawm cov hlau thiab tsim ib txheej graphite dub rau sab nrauv ntawm cov hlau. Cam khwb cia hlau muaj zoo machinability, castability, thiab fluidity.
