Nyob rau hauv dav dav,Cov plaub cov yeeb nkab cov yeeb nkab qib tsis tuaj yeem cuam tshuam tsis tau, vim tias txhua tus qauv yog tsim rauKev Pabcuam Tshwj XeebthiabKev Xeem Yuav TsumCov. Txawm li cas los xij, hauv qee kis, hloov chaw tsawg yog txais tau yog tias pom zoo los ntawm qhov project engineering specification lossis cov neeg siv khoom.
| Lub hom phiaj | Raug | Nws tuaj yeem hloov chaw? | Hais lus |
|---|---|---|---|
| ASTM A106 GR.B | High - kub thiab siab - qhov kev pab cuam siab | ✅ Muaj peev xwm qee zaum hloov API 5L GR.B (PSL1)Rau Kev Pab Cuam Pipeline Kev Pab Cuam | Muaj zog ntawm cov dej kub tab sis tsis cuam tshuam - yuav sim rau qis- Temp kev pabcuam |
| ASTM A53 GR.B | Tsawg -} siab, txheej txheem, lossis dav- lub hom phiaj piping | ⚠️ Tsis pom zoolos hloov A106 lossis A333 | Tsis muaj cov neeg siv khoom nruj thiab cuam tshuam |
| API 5L Gr.b | Kev xa cov roj, roj, thiab dej | ✅ Tuaj yeem qee zaum hloov A106 GR.BHauv kev pabcuam ambient | Yuav tsum ntsib API tshuaj thiab cov tawv me me (tshwj xeeb yog PSL2) |
| ASTM A333 Gr.6 | Tsawg - kev pabcuam kub (-45 degree) | ⚠️ Tuaj yeem hloov A106 / A53 tsuas yog yog ntsuas kub ntau dua lossis sib npaug rau chav sov | Muaj cov kev xeem ntxiv rau kev kuaj rau subzero cov ntawv thov |
Tsis muaj kev sib pauv tau yooj yim: Txhua tus qauv pabcuam ib puag ncig tshwj xeeb (kub, siab, lossis nruab nrab).
Kev Pom Zoo Pom Zoo Yuav Tsum Tau: Substitution should always be validated by the end user, design engineer, or third-party inspector.
Tib Txoj Kev:
A106 GR.B ≈ API 5L GR.B (rau Kev Ntsuas Siab Rau Cov Pipelines)
A333 Gr.6 ≠ A106 GR.B (kev ua haujlwm kub sib txawv)
A53 Gr.byog tsuas yog rau qis - h siab lossis cov qauv tsim qauv, tsis ua hauj lwm.
