Lub Asme B16.5 Txheem Npog Cov Flanges thiab Flange Bolting rau Cov Kav Dej Rau Cov Kav Dej, Li Qub, Thiab Fittings. Hauv qab no yog ib qho dav davFlange Bolting Daim DuabRaws li ASME B16.5, uas suav nrog cov ntsia loj, ntau thiab ntev rau cov chav kawm flange sib txawv thiab ntau thiab tsawg.
ASME B16.5 Flange Bolting Daim Ntawv Teev (Ib nrab)
(Rau Chav Kawm Qib 150, 300, 600, 900, 1500, thiab 2500 flanges)
| Nominal yeeb nkab loj (nps) | Flange Class | Bolt Inch (hauv) | Tus naj npawb ntawm bolts | Bolt lub voj voog Diam (hauv) | Pom zoo ntsia liaj qhov rai ntev (hauv) |
|---|---|---|---|---|---|
| ½" | 150 | ½" | 4 | 3.25 | 2.5 |
| 1" | 300 | ¾" | 4 | 3.75 | 3.0 |

| 8" | 2500 | 1⅛" | 12 | 11.50 | 7.0 |
Sau ntawv:
Cov Khoom Siv Bolt:Feem ntau ASTM A193 B7 (High-zog alloy steel) lossis ASTM A307 (cov hlau roj carbon) nyob ntawm cov kev pabcuam.
Txuas:Hardened Wreakers (ASTM F436) feem ntau siv nyob rau hauv noob txiv.
Torque qhov tseem ceeb:Nyob ntawm cov khoom siv ntsia liaj qhov rooj, lubrication, thiab flange rating (xa mus asme pcc -1}} rau bolt zighting cov txheej txheem).
Daim duab qhia tag nrho:Rau tag nrho cov npe, xa mus rauASME B16.5 Rooj 7 & Lus 8(ntsia liaj qhov ceev thiab qhov loj me) thiabRooj 1a \/ 1B(Flange qhov ntev).
Piv txwv rau chav kawm qib 150 flanges (ib nrab ntawm cov ntaub ntawv):
| Nps | Bolt Txoj Kab | Tsis muaj ntawm bolts | Bolt vajvoog (hauv) |
|---|---|---|---|
| 1" | ½" | 4 | 3.25 |
| 2" | ½" | 4 | 4.75 |
| 4" | ¾" | 8 | 6.00 |
Cov Tswv Cuab Tseem Ceeb:
ASME B16.5:Yeeb nkab flanges thiab flanged fittings.
ASME PCC -1:Cov lus qhia rau lub ciam teb bolted flange sib dhos.
Rau cov ntsia liaj qhov ntev ntev, ib txwm txheeb xyuas nrog flange qhov ntev thiab gasket tuab. Qhia rau kuv paub yog tias koj xav tau cov ntsiab lus rau cov chav kawm flange lossis qhov loj me!
