ASME B16.47 Series A Flange Dimensions
Dec 08, 2025
ASME B16.47qhia qhov ntev, kam rau ua, cov ntaub ntawv, cim, thiab kev ntsuas siab rau loj - txoj kab uas hla yeeb nkab flanges hauv qhov ntau thiab tsawg NPS 26 (DN 650) txog NPS 60 (DN 1500). Cov qauv no suav nrog 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 dig muag flanges.
ASME / ANSI B16.47 muab:
- Weld caj dab flange
- Qhov muag tsis pom flange
ASME B16.47 Flange Marking
- Lub npe: Chaw tsim khoom lub npe lossis lub cim lag luam
- Khoom siv: Cam khwb cia lossis Forged, cov khoom txheem ASTM xxx.
- Kev ntsuas siab: (piv txwv li, Chav Kawm 75, 150, 300, 400, 600, lossis 900).
- Conformance: ASME B16 lossis B16.47 tus qauv.
- Kub: Yog tias qhov ntsuas kub tau sau tseg, qhia qhov ntsuas qhov ntsuas siab sib xws.
- Size: NPE
- Ntiv nplhaib Joint Flanges: Yuav tsum tau cim nrog tsab ntawv R thiab lub nplhaib zawj tooj.
- Multiple Material Marking: Thaum siv ntau yam khoom siv.

ASME B16.47- Loj Diameter Steel Flanges: NPS 26 txog NPS 60, Metric/Inch Standard, B16.47 - 2025
FAQ:
1. Dab tsi yog qhov txawv ntawm Series A thiab Series B flanges?
Qhov sib txawv yog nyob ntawm qhov loj thiab qhov ntau. Series A (MSS SP-44) flanges yog lub cev loj dua, hnyav dua, thiab siv tsawg dua tab sis loj bolts piv rauSeries B (API 605).
2. Qhov luaj li cas ntawm ASME B16.47 Series A yog dab tsi?
ASME B16.47 Series A npog loj - txoj kab uas hla flanges los ntawm NPS 26 txog NPS 60. Rau flanges me dua 26 ntiv tes, koj yuav tsum xa mus rau qhovASME B16.5txheem.
3. Puas yog Series A flanges sib haum nrog ASME B16.5?
Tsis yog. ASME B16.5 tsuas yog npog flanges mus txog NPS 24. Thaum ASME B16.47 tau tsim los txuas ntxiv qhov ntau.
4. Dab tsi yog qhov siab - qhov ntsuas kub rau Series A flanges?
Series A flanges muaj nyob rau hauv Chav Kawm 150, 300, 400, 600, thiab 900. Cov kev ntsuas tshwj xeeb yog nyob ntawm cov khoom siv qib (xws li,Carbon Steel A105los yogStainless hlau Flange) thiab kev khiav hauj lwm kub.
5. Vim li cas Series A flanges kim dua Series B?
Series A flanges hnyav dua thiab xav tau cov khoom siv raw.
6. "MSS SP-44" yuav ua li cas rau ASME B16.47 Series A?
Series A yog tus ua tiav rau MSS SP-44. Niaj hnub no, Series A suav nrog qhov ntev thiab qhov tshwj xeeb uas muaj nyob hauv MSS SP-44.
7. Dab tsi yog cov khoom siv tshaj plaws rau Series A flanges?
Cov ntaub ntawv muaj xws li ASTM A105 (Carbon Steel),ASTM A350 LF2(Tsawg-temp Carbon Steel), thiab ASTM A694 (Qib F42 txog F70) rau siab- cov ntawv thov cov raj xa dej. Stainless hlau thiab Duplex alloys kuj muaj rau corrosive ib puag ncig.
8. Puas Series A flanges tuaj nyob rau hauv hom "Dis muag" thiab "Weld Neck"?
Yog lawm. Series A feem ntau tsom rau Weld Neck (WN) thiab hom dig muag flange.
9. Tus txheej txheem Facing rau cov flanges yog dab tsi?
Feem ntau yog Raised Face (RF), feem ntau nrog 0.06 "(1.6mm) lossis 0.25" (6.4mm) qhov siab. Ring Type Joint (RTJ) lub ntsej muag kuj tau siv dav hauv Chav Kawm 600 thiab 900 rau siab - kev pabcuam roj thiab roj.
