Basic qhia txog flange
Cov yeeb nkab flanges thiab lawv cov gaskets thiab fasteners yog sib sau ua ke hu ua flange pob qij txha.
Daim ntawv thov:
Flange sib koom ua ke yog ib yam ntawm cov khoom siv dav siv hauv engineering tsim. Nws yog ib qho tseem ceeb ntawm kev tsim cov kav dej, cov yeeb nkab fittings thiab li qub, thiab tseem yog ib qho tseem ceeb ntawm cov khoom siv thiab cov khoom siv (xws li manhole, pom iav qib ntsuas, thiab lwm yam). Tsis tas li ntawd, flange pob qij txha feem ntau yog siv rau hauv lwm yam kev qhuab qhia, xws li kev lag luam furnaces, thermal engineering, dej thiab dej ntws, cua sov thiab qhov cua, tswj tsis siv neeg, thiab lwm yam.
Texture ntawm cov khoom:
Forged steel, WCB carbon steel, stainless hlau, 316L, 316, 304L, 304, 321, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, molybdenum titanium, roj hmab hauv ob sab phlu, fluorine hauv ob sab phlu.
Kev faib tawm:
Flat vuam flange, caj dab flange, taub qab vuam flange, nplhaib txuas flange, qhov (socket flange), thiab qhov muag tsis pom phaj, thiab lwm yam.
Executive standard:
Muaj GB series (tus qauv hauv tebchaws), JB series (tus kws kho tshuab), HG series (chaw tshuaj tshuaj), ASME B16.5 (American standard), BS4504 (British standard), DIN (German standard), JIS (Japanese standard).
International yeeb nkab flange txheem system:
Muaj ob lub ntsiab thoob ntiaj teb cov yeeb nkab flange qauv, uas yog European yeeb nkab flange system sawv cev los ntawm German DIN (xws li qub Soviet Union) thiab American yeeb nkab flange system sawv cev los ntawm American ANSI yeeb nkab flange.
1. Phaj hom tiaj vuam flange
qhov zoo:
Nws yog qhov yooj yim kom tau txais cov ntaub ntawv, yooj yim rau kev tsim, tsis tshua muaj nqi thiab siv dav.
Qhov tsis zoo:
Vim nws tsis zoo rigidity, nws yuav tsum tsis txhob siv nyob rau hauv cov txheej txheem piping systems nrog cov kev xav tau ntawm cov khoom thiab kev thov, flammability, explosiveness thiab siab nqus tsev kawm ntawv, thiab nyob rau hauv cov xwm txheej txaus ntshai heev.
Lub sealing nto hom muaj tiaj tus thiab convex nto.
2. tiaj vuam flange nrog caj dab
Lub plhaw-on vuam flange nrog caj dab belongs rau lub teb chaws tus qauv flange txheem system. Nws yog ib daim ntawv ntawm lub teb chaws tus qauv flange (tseem hu ua GB flange) thiab ib qho ntawm cov flanges feem ntau siv rau cov khoom siv lossis cov kav dej.
qhov zoo:
Lub installation ntawm qhov chaw yog yooj yim, thiab cov txheej txheem ntawm vuam seam rubbing tuaj yeem raug tshem tawm
Qhov tsis zoo:
Lub caj dab qhov siab ntawm plam-on vuam flange nrog lub caj dab yog qis, uas txhim kho lub rigidity thiab bearing peev xwm ntawm lub flange. Piv nrog rau lub taub qab vuam flange, vuam workload yog loj, kev noj cov vuam pas nrig yog siab, thiab nws tsis tuaj yeem tiv taus qhov kub thiab txias siab, rov kho dua thiab kub hloov pauv.
3. Lub caj dab taub qab vuam flange
Lub sealing nto daim ntawv ntawm lub caj dab taub qab vuam flange muaj xws li:
RF, FM, M, T, G, FF.
qhov zoo:
Kev sib txuas tsis yooj yim rau deform, cov nyhuv sealing zoo, thiab nws yog dav siv. Nws yog qhov tsim nyog rau cov kav dej uas muaj qhov hloov pauv loj hauv qhov kub thiab txias, qhov kub thiab txias, kev kub siab thiab qis qis, thiab tseem siv rau cov kav xa hluav taws xob thauj khoom kim tshaj tawm, hluav taws kub thiab hluav taws xob, thiab cov pa phem.
Qhov tsis zoo:
Lub caj dab pob tw-welding flange yog loj, loj, kim, thiab nyuaj rau nruab thiab nrhiav. Yog li ntawd, nws yooj yim dua rau pob thaum lub sij hawm thauj mus los.
4. Qhov (socket) vuam flange
Qhov (socket) vuam flangeyog flange welded nrog steel yeeb nkab ntawm ib kawg thiab bolted ntawm lwm kawg.
Sealing nto hom:
Nce lub ntsej muag (RF), concave thiab convex ntsej muag (MFM), tenon thiab zawj lub ntsej muag (TG), nplhaib sib koom lub ntsej muag (RJ)
Scope ntawm kev siv:
Boiler thiab siab nkoj, roj av, tshuaj, shipbuilding, kws, metallurgy, machinery, stamping luj tshib zaub mov thiab lwm yam lag luam.
Feem ntau siv hauv cov kav dej nrog PN ≤ 10.0MPa thiab DN ≤ 40.
5. Xov flange
Threaded flange yog ib qho uas tsis yog-welded flange, uas ua cov txheej txheem sab hauv ntawm lub flange rau hauv cov yeeb nkab xov thiab txuas nrog cov yeeb nkab threaded.
qhov zoo:
Piv nrog lub tiaj vuam flange lossis pob tw vuam flange,threaded flangemuaj cov yam ntxwv ntawm kev yooj yim installation thiab txij nkawm, thiab tuaj yeem siv rau ntawm qee cov kav dej uas tsis tso cai rau welded rau ntawm qhov chaw. Alloy steel flange muaj lub zog txaus, tab sis nws tsis yooj yim rau vuam, lossis qhov kev ua haujlwm vuam tsis zoo, threaded flange kuj tuaj yeem xaiv.
Qhov tsis zoo:
Thaum qhov kub ntawm cov raj xa dej hloov pauv sai heev lossis qhov kub siab tshaj 260 ℃ thiab qis dua - 45 ℃, nws raug nquahu kom tsis txhob siv cov xov flange kom tsis txhob xau.
6. Qhov muag tsis pom flange
Kuj tseem hu ua flange npog thiab qhov muag tsis pom phaj. Nws yog flange tsis muaj qhov nyob nruab nrab rau kev sib khi cov yeeb nkab ntsaws.
Kev ua haujlwm yog tib yam li lub taub hau welded thiab threaded yeeb nkab cap, tsuas yog qhov ntawdqhov muag tsis pom flangethiab threaded yeeb nkab cap tuaj yeem raug tshem tawm txhua lub sijhawm, thaum lub taub hau welded tsis tuaj yeem.
Flange npog sealing nto:
Flat (FF), tsa ntsej muag (RF), concave thiab convex ntsej muag (MFM), tenon thiab zawj ntsej muag (TG), nplhaib sib koom lub ntsej muag (RJ)
