Dab tsi yog qhov feem ntau flange

1. Dab tsi yog qhov chaw zoo tshaj plaws?

Feem ntau hom flange siv thoob plaws kev lag luam yog lubWeld Neck FlangeCov. Nws cov chaw muaj koob meej stems los ntawm nws versatility, lub zog, thiab siab-kub, thiab cov ntaub ntawv tseem ceeb (piv txwv li cov roj thiab cov roj ua haujlwm).

Weld Neck Flanges muaj lub caj dab ntev, tapered uas yog welded rau cov yeeb nkab, faib cov kev kub ntxhov thiab txo cov cua hauv dej ntws. Cov qauv kev tsim no minimizes zam kev pheej hmoo thiab tso cai rau cov txheej txheem yooj yim thaum lub teeb nruab. Lawv muaj nyob rau hauv ntau cov ntaub ntawv (carbon hlau, hlau steel, alloy hlau) thiab siab cov txheej txheem, cov qauv kev siv, DIN cov qauv), ua rau lawv hloov tau ntau yam kev ua haujlwm.

2. Ob hom ntawm cov flanges yog dabtsi?

Flanges yog cov catally categorized rau ob hom loj raws li lawv txoj kev sib txuas mus rau cov yeeb nkab:

Welded flanges: Cov flanges no tau txuas mus tas li rau cov yeeb nkab ntawm vuam, kom ntseeg tau ib lub zog, dej siab-resistant foob. Cov subtypes xws li:

Weld Neck Flanges (raws li tau piav saum toj no).

Qhov (qhov chaw weld flanges (nrog lub qhov quav kom haum rau cov yeeb nkab kom haum, welded sab nraud rau me-diam, cov tshuab siab siab).

Nplaim-rau Flanges (npleem hla cov yeeb nkab thiab muaj welded ntawm ob sab, zoo tagnrho rau cov ntawv thov tsawg-).

Threaded flanges: Cov flanges muaj sab hauv cov xov uas phim cov xov sab nraud ntawm cov yeeb nkab, tso cai rau lub bolt-dawb kev sib txuas. Lawv tau siv nyob rau hauv qis-siab, tsis yog-tseem ceeb siv nyiaj (piv txwv li, dej muab, cov dej ntws me me) qhov twg vuam yog qhov tsis sib xws.

3. Yuav ua li cas kom paub hom flange?

Txheeb xyuas lub ntsej muag flange cuam tshuam nrog kev kuaj cov ntsiab lus tseem ceeb thiab cov lus qhia tshwj xeeb:

Txoj kev sib txuas:

Welded flanges muaj qhov du, tsis tu ncua bore thiab yuav qhia tau Weld cov cim ze ntawm caj dab.

Threaded flanges tau pom sab hauv xov (kos nrog lub teeb lossis kev sojntsuam).

Cov duab thiab tsim qauv:

Weld Neck Flanges muaj lub caj dab ntev, tapered uas sib xyaw nrog cov yeeb nkab.

Npleem-ntawm flanges yog tiaj tus nrog lub bore me ntsis loj dua li cov yeeb nkab loj dua li cov yeeb nkab, haum rau nws.

Qhov (socket) weld flanges muaj cov recessed (recessed (recessed

Qhov muag dig muag flanges yog cov tawv tawv uas tsis muaj lub bore, siv los ntim cov yeeb nkab xaus.

Qhov loj me thiab qauv:

Txheeb xyuas cov yeeb nkab nominal loj (NPS), thiab, ____00, 600, thiab ntsej muag ntsej muag, lub ntsej muag tiaj, nplhaib sib koom tes).

Xa mus rau cov qauv zoo li Ansi / ASME B16.5, DIN 2501, lossis JIS B2220 rau kev tsim tawm.

Cov ntsiab lus thov:

Cov tshuab hluav taws xob siab feem ntau siv weld caj dab flanges.

Tsawg-siab, cov teeb tsa ib ntus yuav siv txoj hlua lossis cov flanges.

4. Dab tsi yog lub tooj liab flange?

Lub ntsej muag tooj liab yog cov flange tau los ntawm tooj liab lossis tooj liab, tooj liab), muaj nuj nqis rau nws cov khoom muag zoo, corrosion kuj, thiab malleability.

Cov Ntawv Thov: Feem ntau siv nyob rau hauv kav dej, cua sov, cua txias, thiab ua zaub mov. Tooj liab tsis kam rau xeb thiab cov kab mob ua rau nws haum rau cov dej dej muaj peev xwm.

Nta: Yooj yim rau tshuab thiab cam / braze, kom muaj kev ruaj ntseg sib txuas. Txawm li cas los xij, tooj liab flanges tau qis tensile muaj zog dua li hlau, txwv lawv siv hauv kev siv siab lossis kub-ntsuas tshuab.

LamOs: Brass flanges (tooj liab-zinc) muaj lub zog zoo dua, ua kom tooj-tin) Excel rau corrosion tsis kam, ua rau lawv zoo tshaj rau cov tub rog ib puag ncig.
