Dab tsi ASTM A106 Tiag npog
ASTM A106 1yog lub npe "Standard Specification for Seamless Carbon Steel Pipe for High-Tsub Service." Cov kab lus tseem ceeb yog siab -kev pabcuam kub - tus qauv no tau sau rau cov kav dej uas yuav pom qhov ua haujlwm siab, tsis yog siab siab xwb. Nws suav nrog peb qib (A, B, thiab C), uas Qib B yog nyob deb ntawm cov khoom lag luam feem ntau thiab tau teev tseg vim nws qhov sib npaug ntawm lub zog thiab vuam.
Chemical Composition Requirements (Qib B)
| Element | Limit (max tshwj tsis yog sau tseg) |
|---|---|
| Cov pa roj carbon (C) | 0.30% max |
| Manganese (Mn) | 0.29% – 1.06% |
| Phosphorus (P) | 0.035% max |
| Sulfur (S) | 0.035% |
| Silicon (Si) | 0.10% min |
| Chromium (Cr) | 0.40% max |
| Copper (Cu) | 0.40% max |
| Molybdenum (hli) | 0.15% max |
| Nickel (Ni) | 0.40% max |
| Vanadium (V) | 0.08% max |
Cov kev txwv sib xyaw ua ke rau Cr + Cu + Mo + Ni + V kuj tseem muaj nyob rau hauv cov lus qhia - cov ntsiab lus uas tsis yooj yim rau nco yog tias koj tsuas yog xyuas cov ntsiab lus ntawm lub rooj.
Mechanical Property Requirements (Qib B)
- Tensile zog:60,000 psi (415 MPa) yam tsawg kawg nkaus
- Yield zog:35,000 psi (240 MPa) yam tsawg kawg nkaus
- Elongation:Xam rau ib qho piv txwv (nws txawv ntawm phab ntsa tuab thiab qhov loj me, raws li tus qauv elongation formula - tsis yog feem pua ntawm txhua qhov ntau thiab tsawg)
A106 Qib B vs.A53Qib B: Cov neeg yuav khoom sib piv xav tau tiag tiag
Ob qho no feem ntau tsis meej pem vim tias lawv sib tshooj hnyav ntawm qhov loj thiab qee zaum tus nqi zoo sib xws, tab sis lawv tsis yog tib yam khoom:
- A106yog sau tshwj xeeb rau siab - kev pabcuam kub thiab muaj kev tswj xyuas nruj dua (tseem ceeb ntawm cov ntsiab lus silicon, uas A53 tsis qhia qhov tsawg kawg nkaus rau).
- A53npog ob qho tib si seamless thiab welded (ERW) yeeb nkab, thiab suav nrog kev xaiv txheej / galvanizing (Hom S, Hom E, Hom F) uas A106 tsis muaj.
- A106 yog seamless nkaus xwb- tsis muaj welded version raws li qhov tshwj xeeb no.
- Hauv kev xyaum, A106 Qib B feem ntau yog qhov kev xaiv raug rau cov txheej txheem thiab siab -kub piping, thaum A53 feem ntau yog rau cov qauv, qis- siab, thiab kev siv hluav taws xob- qib kev siv.
Yog tias koj qhov phiaj xwm tshwj xeeb hu rau A106 tshwj xeeb, hloov A53 - txawm tias qhov sib npaug - tsis yog kev hloov pauv raws li.
Kev Ntsuas & Kev Ntsuas Zoo
Vim tias qhov tshwm sim tsis ua tiav yog qhov hnyav dua nyob rau hauv siab - kev pabcuam siab, kev sim ntsuas feem ntau mus dhau qhov kev kuaj xyuas zeb:
- Kev ntsuam xyuas hydrostaticmus rau ib qho kev ntsuas ntsuas siab (feem ntau 1.5 × tsim siab) ntawm 100% ntawm kev tsim khoom
- Kev kuaj ultrasonic (UT)rau phab ntsa thickness pov thawj thiab sab hauv qhov tsis xws luag
- Eddy tam sim no xeem (ECT), feem ntau rau nyias - phab ntsa tubing qhov twg UT rhiab heev yog txwv
- Positive Material Identification (PMI), tshwj xeeb tshaj yog ib qho tseem ceeb rau cov qib alloy (P11/P22/P91) qhov sib tov-ups ntawm zoo sib xws- saib yeeb nkab tuaj yeem ua rau loj hauv - kev pabcuam tsis ua haujlwm
- Charpy V- ntsuas qhov cuam tshuamrau qis- kub los yog siab - yuav tsum muaj toughness
Cov lus nug nquag nug (FAQ)
Q: Qhov siab tshaj plaws ua haujlwm kub rau A106 Qib B yeeb nkab yog dab tsi?
A: Tsis muaj ib qho kev ruaj khov siab tshaj plaws tau teev tseg hauv A106 nws tus kheej - tso cai kev ntxhov siab ntawm qhov ntsuas kub tau txiav txim siab siv ASME B31.3 (lossis B31.1, nyob ntawm txoj cai tswjfwm) cov lus kev ntxhov siab, uas qhia tias qhov kev ntxhov siab tso cai txo qis li qhov kub thiab txias. Koj tus kws tsim cov kav dej yuav tsum paub meej tias muaj kev ntxhov siab rau ntawm koj qhov tshwj xeeb tsim qhov kub thiab txias es tsis txhob cia siab rau cov duab siab tshaj plaws.
Q: A106 Qib B puas tuaj yeem siv rau kev pabcuam qaub (H₂S-muaj kua)?
A: Tsis yog yam tsis muaj kev tsim nyog ntxiv. Standard A106 Qib B tsis suav nrog cov hardness thiab kev tswj hwm uas xav tau los ntawm NACE MR0175 / ISO 15156 rau kev pabcuam qaub. Yog tias xav tau H₂S raug, qhov no yuav tsum tau muab cais tawm thiab txheeb xyuas qhov kev xav tau kev pabcuam qaub - tsis txhob xav tias tus qauv A106 tau txais txiaj ntsig.
Q: Puas yog A106 Qib B yeeb nkab haum rau vuam?
A: Yog, A106 Qib B feem ntau yog weldable siv cov txheej txheem carbon steel vuam, thiab nws cov ntsiab lus carbon (0.30% max) yog tswj ib feem nrog weldability hauv siab. Txawm li cas los xij, rau cov phab ntsa hnyav lossis cov kev pabcuam tshwj xeeb, kev tsim nyog preheat thiab vuam txheej txheem tsim nyog yuav tsum tau ua raws li koj qhov project txoj cai vuam.
Q: Qhov txawv ntawm A106 Qib A, B, thiab C yog dab tsi?
A: Peb qib sib txawv ntawm lub zog: Qib A muaj lub zog qis tshaj plaws thiab siab tshaj plaws ductility, Qib B yog qhov feem ntau siv nrog lub zog nruab nrab, thiab Qib C muaj lub zog siab tshaj plaws tab sis tsis tshua muaj khoom. Qib B yog qhov kev xaiv zoo tshaj plaws rau feem ntau qhov siab tshaj -kub piping tshwj tsis yog tias ib qho laj thawj tshwj xeeb hu rau A lossis C.
