2. Cov yam ntxwv tseem ceeb ntawm ASME B16.5 flanges
A. Flange hom
| Ntaus | Kev piav txog | Kev Siv Ntau |
|---|---|---|
| Weld Neck (WN) | Welded rau yeeb nkab rau cov tshuab siab siab | Cov xov xwm tseem ceeb, ib puag ncig muaj kev nyuaj siab |
| Fella-rau (yog li) | Swb dua cov yeeb nkab & fillet welded | Tsawg-siab, Yooj Yim Installation |
| Qhov (socketing weld (sw) | Yeeb nkab ntsaws rau hauv flange & welded | Me-Bore, Kev Ntsuas Siab |
| Siv Txhaum (LJ) | Siv nrog cov qij xaus rau cov txheej txheem yooj yim | Cov tshuab yuav tsum nquag nquag disassembly |
| Threaded (thd) | Screwed rau hauv cov yeeb nkab (tsis muaj vuam xav tau) | Tsawg-siab, tsis yog cov ntawv thov tseem ceeb |
| Dig muag (bl) | Kaw cov tshuab raj | Kev kuaj, cais, lossis yav tom ntej nthuav dav |
B. Kev Ntsuas Kub-Ntsuas
NyiasChav Kawm Siab (150, 300, 600, thiab lwm yam)Muaj qhov siab tshaj plaws uas tau tso cai rau cov kub ntawm cov kub.
Piv txwv li: aHoob 150 FlangeMuaj peev xwm kov ~ 285 psi ntawm chav temp tab sis tsawg dua ntawm Temps ntau dua.
C. Flange ntsej muag
| Lub ntsej muag hom | Kev piav txog | Cov Ntawv Thov |
|---|---|---|
| Lub ntsej muag tsa lub ntsej muag (RF) | Me ntsis tsa saum npoo (1\/16 "lossis 1\/4") | Feem ntau rau kev siv dav dav |
| Tiaj Tus Ntsej Muag (FF) | Nkhaus tiaj | Tsawg-siab, tsis yog xim hlau gaskets |
| Ntiv nplhaib-hom sib koom yeem (RTJ) | Grooved Rau Hlau Nplhaib Gaskets | Kev Kub Siab \/ Kub (Kub (piv txwv li, Roj & Roj) |
D. Cov ntaub ntawv
Cov Khoom Siv Uas Ua IbASTM qauv:
Carbon Steel:A105, A350 LF2
Tus Hlau Stainless: A182 F304/F316
Alloy Steel: A182 F11, F22
3. ASME B16.5 thiab lwm cov qauv Flange
| Yam zoo | ASME B16.5 | ASME B16.47 (Cov Flange Loj) | ASME B16.11 (Forged Fittings) |
|---|---|---|---|
| Loj npaum li cas | ½" – 24" | 26" – 60" | Mus txog 4 " |
| Kev ntsuas siab siab | 150 – 2500 | 75 – 900 | 2000 – 9000 |
| Flange hom | Wn, yog li, Sw, LJ, THD, Tawg | Wn, Bl tsuas yog | Qhov chaw weld, threaded |
| Cov Ntawv Thov | Industrial Kev Lag Luam | Loj Hlav | High-Siab Me-Bore Tshuab |
4. Yuav ua li cas xaiv txoj cai B16.5 Flange?
Txheeb xyuas qhov loj me (nps)- phim yeeb nkab taub.
Xaiv Chav Kawm Siab- Raws li cov txheej txheem kom ua.
Xaiv hom flange- Weld caj dab rau kev kub siab, swb-rau rau qhov yooj yim nruab.
De lub ntsej muag hom- RF (feem ntau cov), ff (rau cov gaskets), RTJ (siab siab).
Cov khoom siv xaiv- Carbon Steel rau kev siv dav dav, stainless rau corrosion tsis kam.
5. Cov kev lag luam ib txwm siv ASME B16.5 flanges
✔ Roj & Roj- Pipelines, Rechnies
✔ Tshuaj Nroj Tsuag- Acid & corrosive kua floling
✔ Lub Zog Loj- Chav, Boiler Tshuab
✔ Kev Kho Mob Dej- Loj-diamer dej kav
6. Cov hloov tshiab tshiab & hloov kho
ASME B16. {5-2020yog cov ntawv tshaj tawm tsis ntev los no (tshawb xyuas rau kev hloov kho tshiab tiag tiag).
Kev hloov pauv suav nrog cov ntaub ntawv tshiab, thev naus laus zis lossis cov txheej txheem sim.
Kawg Ntsiab Lus Kawg
ASME B16.5yog tusmus-rau tus qauvrau cov flanges los ntawm ½ "txog 24".
