Txheem vs Custom Flange
Txheem flange:Qhia meej alloy, hom, DN / NPS, tus qauv (ASME B16.5 / EN 1092-1 / JIS B2220), qib siab (Class 150 / PN16), thiab tig ntsej muag (FF / RF). Peb siv lub rooj zaum txheem txheem.
Kev cai flange:Yog tias koj xav tau tsis yog - qauv OD, bore, PCD, bolt qauv, thickness, los yog tig mus rau - xa ib daim duab nrog txhua qhov ntev. Peb tsim raws li koj cov spec.
Tseem ceeb:EN 1092-1 (PN series) thiab ASME B16.5 (Class series) muaj qhov sib txawv rau tib DN. Piv txwv li, DN150 PN16 muaj OD 285mm / PCD 240mm / 8 × Ø22mm - ze rau tab sis tsis zoo ib yam nrog ASME B16.5 Class 150 (OD 279mm / PCD 241.3mm). Nco ntsoov paub meej cov txheej txheem ua ntej xaj.
Yuav ntsuas qhov Flange uas twb muaj lawm
Yog tias koj tsis paub tus qauv, ntsuas qhov flange uas twb muaj lawm:
OD- Txoj kab uas hla loj tshaj plaws ntawm lub flange
Npog- Qhov qhib qhov taub
Thickness- Flange ntsej muag
Bolt qhov- Suav lawv, ntsuas ib lub qhov taub
PCD- Ntsuas qhov nruab nrab-rau- nruab nrab ntawm qhov nruab nrab ntawm qhov ntsia hlau (los yog hla tus qauv)
Kev ntsib- Lub ntsej muag tiaj tus lossis tsa ntsej muag?
Hom- SO / WN / BL / TH / SW / LJ / PL?
Diam duab nrog tus pas ntsuas los yog caliper nyob ib sab ntawm lub flangepab peb txheeb xyuas nws sai.

FAQ
Dab tsi yog qhov tseem ceeb tshaj plaws flange qhov ntev?
OD, bore, thickness, PCD, ntsia liaj qhov rooj - qhov taub, thiab tus naj npawb ntawm lub qhov ntsia hlau. Ntxiv rau hom flange, tig ntsej muag, qauv, thiab chav kawm siab. Saib ASME B16.5 cov lus saum toj no rau cov txiaj ntsig tiag.
Puas yog flange bore tib yam li yeeb nkab ID?
Tsis yog. Rau Slip-Ntawm flanges, lub bore phim cov yeeb nkab OD (tsis yog ID). Rau Weld Neck, tho qhov sib tw yeeb nkab ID ib lub sijhawm. Rau qhov muag tsis pom flanges, tsis muaj bore.
Puas yog DN qhia kuv qhov flange qhov ntev?
Tsis yog. DN tsuas yog nominal xwb. A DN150 Class 150 flange muaj OD 279mm, PCD 241.3mm, 8 × Ø22mm qhov, thickness 25.4mm - tsis muaj qhov sib npaug "150".
Dab tsi yog qhov txawv ntawm FF thiab RF ntsej muag?
FF yog flush; RF muaj lub rooj zaum gasket (1.6mm rau DN Tsawg dua lossis sib npaug rau 300). Lawv tsis hloov pauv tau - mating flange ntsib yuav tsum sib phim.
Koj puas tuaj yeem ua flanges saum DN350?
Yog, raws li kev cai ntau lawm. Xa ib daim duab nrog OD, bore, thickness, PCD, bolt qauv, thiab tig ntsej muag.
Dab tsi alloy kuv yuav tsum siv rau lub siab flange?
6061-T6 yog tus qauv rau feem ntau daim ntawv thov. Siv 5083 rau marine. Siv 1060/3003 tsuas yog rau qis -siab, kev pabcuam tsis tseem ceeb.
