1. Kev ua haujlwm siab kub-kub
| Chaw ua uas tsis tau haus | Hoob 150 | Hoob 300 |
|---|---|---|
| Chav Temp (100 Qib F \/ 38 Degree) Kev Ntsuas | 275 psi | 720 psi |
| 400 degree f (204 degree) ntsuam xyuas (A105) | 200 psi | 570 psi |
| 600 degree f (316 degree) kev ntaus nqi (A105) | 140 psi | 395 psi |
| Hydrostatic kuaj siab | 450 PSI | 1,125 psi |
Cov tswv yim tseem ceeb:Hoob 300 \/ tswj tau cov peev txheej siab dua nyob rau kev nce siab kub
2. Lub cev nqaij daim tawv
| Nps 4 "Flange | Hoob 150 | Hoob 300 |
|---|---|---|
| Od | 10.00" | 11.00" |
| Qhov tuab | 1.06" | 1.38" |
| Bolt Vvende Diam | 8.50" | 9.00" |
| # ntawm bolts | 8 | 8 |
| Lub ntsia ci loj | 3/4" | 7/8" |
| Qhov hnyav (carbon hlau) | 16. {0 lbs | 25.5 lbs |
Nco tseg:Chav kawm 300 yuav tsum tau ~ 60% ntau hlau loj rau tib nps
3. Cov kev txiav txim siab
Hoob 300 \/ flangesfeem ntau yuav tsum:
Thicker hub ntu
Siab dua qib bolts (ASTM A193 B7 VS A307)
Gaskets ntau dua (muab kauv vs mos graphite)
4. Tus nqi sib piv
| Yam tseem ceeb | Hoob 150 | Hoob 300 |
|---|---|---|
| Flange Nqi | $ 1. {00 (baseline) | 1.8-2.5x |
| Tus nqi them | Qis dua (bolts me) | Siab dua (torque yuav tsum tau) |
| Lub Neej Nqi | Qis dua rau cov kev pabcuam me | Zoo dua rau cov mob hnyav |
5. Daim ntawv thov cov lus qhia
Xaiv chav kawm 150 thaum:
Ua Haujlwm Siab<200 psi at operating temperature
Tsis yog-tseem ceeb ntawm cov dej \/ Cov Kev Pab Cua
Pob nyiaj siv nyiaj txiag-risticts
Chaw muaj kev txwv nyob muaj nyob
Xaiv chav kawm 300 thaum:
Process requires >200 psi ntawm qhov kub
Tuav cov kua dej txaus ntshai
Cyclic chaw thau khoom
Yav Tom Ntej Kev nthuav dav
6. Kev lag luam tawm
| Yam | Hoob 150 Exfib | Hoob 300 \/ tau hloov dua |
|---|---|---|
| Qho hnyav | ✓ (sib dua) | × (hnyav dua) |
| Qhov Chaw Tsum Tau | ✓ (Kev Ua Lag Luam) | × (hneev loj) |
| Lub peev xwm siab | × (txwv) | ✓ (siab dua) |
| Kev Ruaj Ntseg | × (qis dua) | (Ntau dua) |
| Kev co | × (txom nyem) | ✓ (Zoo dua) |
Pro tswv yim:Rau cov neeg sib ciam teb hauv ciam teb (piv txwv li, 250 psi psat f), ib txwm xaiv cov chav kawm siab dua - tus nqi tsawg dua muab kev nyab xeeb thiab muaj txiaj ntsig kev nyab xeeb.
