ASME B16.5 Flange Qhov ntau thiab tsawg
Nov 19, 2025
ANSI / ASME B16.5 Flange Qhov Loj thiab Qhov Loj Specification
General:
ASME B16.5 Txuj yog txwv rau cov yeeb nkab flanges thiab flanged fittings, dig muag flanges, txo flanges, thiab lwm yam flange bolts, flange gaskets, thiab flange pob qij txha. Nws npog flanges ntawm cov chav kawm siab 150, 300, 400, 600, 900, 1500, thiab 2500. Qhov ntau thiab tsawg yog muab rau hauv metric thiab US kev cai units los ntawm NPS 1⁄2 txog NPS 24.
ASME / ANSI B16.5 muab:
- Weld caj dab flange
- Nias- ntawm flange
- Qhov (socket) weld flange
- Qhov muag tsis pom flange
- Threaded flange
- Lap sib koom flange
Loj
Hauv NPS, yog kev xaiv rau nominal flange lossis flange fittings loj. NPS ntsig txog nominal txoj kab uas hla, DN hauv cov qauv thoob ntiaj teb, kev sib raug zoo raws li hauv qab no:
| NPS | DN |
| 1⁄2 | 15 |
| 3⁄4 | 20 |
| 1 | 25 |
| 1 1⁄4 | 32 |
| 1 1⁄2 | 40 |
| 2 | 50 |
| 2 1⁄2 | 65 |
| 3 | 80 |
| 4 | 100 |
CEEB TOOM: Rau NPS Ntau dua lossis sib npaug rau 4, qhov cuam tshuam DN yog DN=25 (NPS).
Cov cim
- 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 150, 300, 400, 600, 900, 1500, lossis 2500)
- Conformance: ASME B16.5 lossis lwm tus qauv B16.
- Kub: Yog tias qhov ntsuas kub tau sau tseg, qhia qhov ntsuas qhov ntsuas qhov 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.
Khoom siv
- ASTM A105 forged carbon hlau flange
- ASTM A350 forged carbon steel, qis alloy steel flange
- ASTM A182 rau alloy steel flange thiab stainless hlau flange
- ASTM A216 for casting carbon steel flanges
- ASTM A352, ASTM A217
- ASTM A515 Gr 70, 65 rau daim hlau flange
- ASTM A516 Gr 70, 65 rau carbon thiab qis alloy steel phaj flange
- ASTM A203, A204, ASTM A203 thiab A204
- ASTM A387 Gr 11, 22, 91 CL2 rau alloy steel phaj flange

(4) Cov flanges no tej zaum yuav muab nrog lub ntsej muag tiaj tus. Lub ntsej muag tiaj tej zaum yog tag nrhotf dimension ntawm thickness ntxiv 2 mm orthetf dimension thickness tsis tau tsa lub ntsej muag qhov siab.
(5) Lub flange qhov ntev tau piav qhia yog rau cov khoom siv tsis tu ncua 1.5-mm tsa lub ntsej muag (tshwj tsis yog lapped); rau cov kev xav tau ntawm lwm qhov kev sib ntsib, saib daim duab 6.
(6) Rau vuam kawg bevel.
(7) Rau xov ntawm threaded flanges.
(8) Dimensions nyob rau hauv kab 13 sib haum mus rau sab hauv diameters ntawm cov yeeb nkab raws li muab nyob rau hauv ASME B36.10M rau txheem phab ntsa yeeb nkab. Thickness ntawm standard wallis tib yam li Teem sijhawm 40 hauv qhov ntau thiab tsawgNPS 10 thiab me dua. Tolerances nyob rau hauv para. 7.5.2 siv. Cov bore qhov ntau thiab tsawg yog cov khoom siv tshwj tsis yog tias tus neeg yuav khoom tau teev tseg.

FAQ:
1. Qhov txawv ntawm ASME B16.5 thiab ASME B16.47 flanges yog dab tsi?
ASME B16.5 npog flange qhov ntau thiab tsawg ntawm 1/2 "mus rau 24" NPS, whereasASME B16.47yog tshwj xeeb rau loj - txoj kab uas hla flanges ntawm 26 "mus rau 60".
2. Kuv puas tuaj yeem siv ASME B16.5 flange rau siab -kev pabcuam hydrogen?
Yog lawm, tab sis kev xaiv cov khoom tseem ceeb heev kom tsis txhob muaj hydrogen embrittlement. Thaum ASME B16.5 txhais qhov ntev thiab qhov ntsuas siab (Class 150-2500), koj yuav tsum xaiv cov ntaub ntawv sib xws xws li ASTM A182 F316L lossis high-nickel alloys.
3. Dab tsi yog qhov siab tshaj plaws ntsuas rau Class 150 flange?
Ib qho kev xav tsis zoo yog tias Chav Kawm 150 sib npaug 150 PSI. Hauv kev muaj tiag, Chav Kawm 150 flange (xws li, A105 carbon steel) tuaj yeem tuav txog 285 PSI (19.6 bar) ntawm qhov kub thiab txias.
4. Yuav ua li cas kuv xam lub bolt lub voj voog txoj kab uas hla rau 8-nti Class 300 flange?
Raws li ASME B16.5, ib qho 8 "Class 300 flange muaj lub voj voog txoj kab uas hla ntawm 10.62 ntiv tes (270 hli) nrog 12 lub qhov taub.Chav kawm 300 qhov ntevdaim duab.
5. Puas muaj qhov sib txawv ntawm "150 lb" thiab "Class 150" flanges?
Technically, "Class 150" yog cov ntsiab lus raug siv los ntawm ASME B16.5. Thaum "150 lb" yog kev lag luam slang.
6. ASME B16.5 txhais li cas "NPS" thiab "DN"?
NPS (Nominal Pipe Size) yog North American inch -raws li kev xaiv, thaum DN (Diameter Nominal) yog qhov ntsuas sib npaug siv hauv ISO / DIN cov qauv. Piv txwv li, NPS 2 yog sib npaug rau DN 50. Txawm li cas los xij, qhov tseeb sab nraud txoj kab uas hla (OD) tseem yog 2.375 "(60.3 hli) txawm tias siv daim ntawv lo.
7. Puas yog 316L stainless hlau zoo dua Duplex 2205 rau B16.5 flanges?
Yog lawm. Duplex 2205 muaj ze li ob npaug ntawm cov txiaj ntsig muaj zog thiab kev ua haujlwm zoo dua rau Kev Nyuaj Siab Corrosion Cracking (SCC) piv rau 316L. Tab sis Duplex 2205 tus nqi yog siab dua li ntawm 316L.
8. Dab tsi yog qhov ua rau flange to hauv Class 600+ systems?
Peb qhov ua rau sab saum toj yog qhov tsis sib xws bolt torque, xaiv cov gasket tsis raug, thiab flange misalignment. Nyob rau hauv siab -siab B16.5 systems (Class 600/900/1500), peb pom zoo kom siv Kauv Kab Mob Gaskets nrog rings puab los tiv thaiv buckling thiab xyuas kom meej ib tug tswj torque txheej txheem ua raws li.
