ASME B16.47 Series B Flange Dimensions
Dec 24, 2025
ASME B16.47 Series B qhia loj - txoj kab uas hla yeeb nkab flanges hauv qhov ntau thiab tsawg NPS 26 (DN 650) txog NPS 60 (DN 1500). Hais txog flange qhov ntev, kam rau ua, cov ntaub ntawv, cim, thiab kev ntsuas siab. Cov qauv no suav nrog cov flanges nrog cov chav kawm siab 75, 150, 300, 400, 600, thiab 900. ANSI B16.47 tus qauv yog txwv rau vuam caj dab flanges thiab qhov muag tsis pom flanges.
ASME / ANSI B16.47 muab:
- Weld caj dab Flange

FAQ:
Q1: Dab tsi yog ASME B16.47 Series B flange?
ASME B16.47 Series B flanges (yav tas los API 605) yog qhov loj -inch steel flanges xws li NPS 26 txog NPS 60.
Q2: Qhov txawv ntawm ASME B16.47 Series A thiab Series B yog dab tsi?
Series A flanges feem ntau hnyav dua thiab siv bolts ntau dua, thaum Series B flanges yog sib dua thiab tsim nrog tsawg dua bolts.
Series B flanges feem ntau pheej yig dua thiab yav tas los hu ua API 605 flanges. Series A flanges yog raws li MSS SP-44 qhov ntev.
Q3: Puas yog ASME B16.47 Series A thiab Series B flanges sib hloov tau?
Tsis yog, lawv tsis hloov pauv. Txawm hais tias lawv npog tib yam NPS ntau yam thiab kev ntsuas siab, lub voj voog lub voj voog thiab tus lej ntawm lub qhov ntsia hlau sib txawv kiag li.
Q4: Vim li cas Series B flanges feem ntau pheej yig dua Series A?
Series B flanges feem ntau yog 10% mus rau 20% pheej yig dua vim tias lawv siv cov khoom siv tsawg. Lawv cov qauv tsim ntau dua ua rau muaj qhov hnyav dua (kg / pc) thiab lub voj voog me me.
Q5: Cov chav kawm siab twg yog them los ntawm ASME B16.47 Series B?
Tus qauv npog cov chav kawm siab 75, 150, 300, 400, 600, thiab 900.
Q6: Dab tsi yog cov khoom siv rau B16.47 Series B flanges?
Cov khoom siv xws li Carbon Steel (ASTM A105 1), Tsawg-Tub kub Carbon Steel (A350 LF2), thiab Stainless hlau (A182 F304L / F316L). Rau cov corrosive offshore ib puag ncig,Duplex F51los yog Super Duplex F53.
Q7: Kuv puas tuaj yeem siv Series B flanges rau ASME B31.3 piping?
Yog lawm. ASME B31.3 (Cov Txheej Txheem Piping) thiab ASME B31.1 (Power Piping) ob leeg paub txog ASME B16.47 raws li tus qauv rau loj - txoj kab uas hla flanges.
Q8: Hom gaskets zoo tshaj rau Series B flanges?
Spiral Wound Gaskets (SWG) yog tus qauv kev lag luam rau Series B.
Q9: Dab tsi yog lub sij hawm txhuas txhuas rau txoj kab uas hla loj Series B flanges?
Rau cov qauv A105 carbon steel, lub sij hawm txhuas feem ntau yog 4 mus rau 6 lub lis piam. Txawm li cas los xij, rau cov hlau tsis muaj steel lossis Duplex Series B flanges hauv qhov ntau thiab tsawg tshaj NPS 48, lub sij hawm txhuas tuaj yeem txuas mus rau 10 mus rau 12 lub lis piam.
