ASME B16,5 Muab Kauv Ntswg Gaskets - Specifications & Qhov Ntev
Muab kauv gaskets muaj feem ntau siv nrog ASME B16.5 flanges thiab yog tsim los muab lub foob cia siab rau hauv cov kev siv siab thiab siab-kub. Hauv qab no yog cov ntsiab lus tseem ceeb hais txog lawv cov kev qhia tshwj xeeb, qhov ntev, thiab cov ntaub ntawv.
1. Kauv Txaj Gasket Qauv & Ua Raws
ASME B16.20: Npog nws yog xim hlau thiab semi-hlau gaskets rau cov yeeb nkab flanges, suav nrog kauv gaskets.
ASME B16.5: Qhia meej flange qhov ntev uas cov gaskets tau siv.
API 601: Txuj ci rau cov gaveric gaskets hauv kev siv cov ntawv thov ua kom huv.
2. Cov khoom plig ua rau muaj txiaj ntsig gasket
| Ib feem | Cov Khoom Siv Khoom Siv |
|---|---|
| Lub nplhaib sab nraud | Carbon Steel (CS), Stainless Hlau (SS 304\/316) |
| Nto Ntiv Nplhaib | Yeem (SS 304\/316, cs) |
| Khoom Siv Ntxawm | Graphite, PTFE, Mica |
| Winding hlau | SS 304, SS 316, inconel, Monel |
3. ASME B16.5 KAUV PHEM GASET qhov ntev
Muab kauv gaskets rau ASME B16.5 flanges tuaj hauv ob qho qauv:
Style R (tsa ntsej muag)- Rau tsa lub ntsej muag tsa (RF) flanges.
Style F (Ca ntsej tim muag)- Rau lub ntsej muag tiaj tus (ff) flanges.

4. Siab-ntsuas kub
Muab Kauv Hniav Gaskets yuav tsum phim cov flange lub siab-kub ntsuas (ib asme b16.5).
| Hom | Max siab (PSI @ 100 Degree F) | Cov Kev Siv Cov Ntawv Siv |
|---|---|---|
| 150 | 285 PSI | Tsawg-siab chav, dej |
| 300 | 740 psi | Kev Ua Piping Piping |
| 600 | 1,480 psi | Cov Hnyav Siab |
| 900 | 2,220 psi | Petrochemical |
| 1500 | 3,705 psi | Fais fab nroj tsuag |
| 2500 | 6,170 psi | High-siab roj |
5. Kev Txhim Kho & Torque Cov Lus Taw Qhia
Bolt Torque:Raws qabASME PCC -1Cov txheej txheem raws li cov khoom siv ntsia hlau thiab cov hom gasket.
Kawm:Xyuas kom meej flange ntsej muag yog huv si thiab tig mus.
Compression:Zam kev sib tiv thaiv kom nruj los tiv thaiv gasket crushing.
6. Cov hom khoom siv kauv nquag gasket
| Ntaus | Khoom Siv Ntxawm | Max temp (Degree F) | Cov Ntawv Thov |
|---|---|---|---|
| Ss 304 + Graphite | Npaim | 850 Qib F (454 degree) | Chav, roj, roj av |
| Ss 316 + ptfe | Ptfe | 450 Qib F (232 Qib) | Corrosive Tshuaj |
| Inconel + Mica | Ib mica | 1,500 degree f (816 degree) | Kev kub siab |
