A105 Cov Ntaub Ntawv Tsis Ua Haujlwm: Sulfide Stress Cracking (SSC)
Ib qho yuam kev engineering feem ntau yog qhia tus qauv ASTM A105 fittings hauv kev pabcuam qaub (H2S-cov kabmob ib puag ncig) yam tsis xav txog kev txwv metallurgical. Standard A105 tsis muaj kev tswj xyuas hardness specifications. Nyob rau hauv cov av qaub, unmitigated hardness spikes nyob rau hauv forging fab tuaj yeem ua rau muaj kev puas tsuaj, brittle hydrogen-induced cracking. Rau cov ntawv thov kev pabcuam qaub, cov kws ua haujlwm yuav tsum qhia ASTM A105N nrog rau qhov siab tshaj plaws hardness txwv ntawm 227 HRC ib NACE MR0175 / ISO 15156.
ASTM A105 fittings puas tuaj yeem txuas ncaj qha rau cov kav hlau carbon steel, thiab xav tau dab tsi preheat?
Yog lawm, ASTM A105 muaj qhov zoo weldability vim nws tswj cov ntsiab lus carbon (max 0.35%). Rau cov qauv phab ntsa thicknesses thiab ambient tej yam kev mob, preheating feem ntau tsis yuav tsum tau. Txawm li cas los xij, rau qhov hnyav dua lossis qis dua ambient kub, preheating rau 100℃-150℃yog tus qauv coj los tiv thaiv hydrogen -induced cracking.
Threaded (NPT) vs. Socket Weld A105 fittings
Lwm qhov kev sib cav sib ceg ntawm cov rooj sib tham engineering yog xaiv ntawm Threaded (NPT) vs. Socket Weld A105 fittings rau me me - tho qhov siab - cov kab siab (NPS Tsawg dua lossis sib npaug rau 2 "), qhov twg qhov (socket welding) yog qhov txaus siab heev rau kev xau- dawb huv raws li kev vibrations hnyav.
Xov Fittings Sealant Xaiv (NPT vs. BSP)
- NPT → siv PTFE daim kab xev, muab tshuaj txhuam, lossis anaerobic sealant

FAQ:
Q: Qhov txawv ntawm ASTM A105 thiab ASTM A106 yog dab tsi?
A: Qhov sib txawv tseem ceeb nyob hauv cov khoom tsim thiab cov qauv tsim khoom. ASTM A105 yog qhov tshwj xeeb rau forged carbon steel piping Cheebtsam (xws li flanges, socket weld / threaded fittings, thiab li qub). Piv txwv li,ASTM A106 1yog cov specification rau seamless carbon steel nominal / ncaj kav. Koj siv A106 rau lub raj xa dej thiab A105 rau kev sib txuas thiab kev sib txuas forged fittings.
Q: ASTM A105N txhais li cas, thiab thaum twg kuv yuav tsum xaiv nws dhau tus qauv A105?
A: Tus "N" xaiv qhov kev kho cua sov zoo li qub. Thaum tus qauv A105 tuaj yeem muab tau raws li -forged rau ambient- rau- cov kev pabcuam nruab nrab, A105N tau dhau los ua cov txheej txheem ua kom zoo dua qub, txo cov kev ntxhov siab, thiab txhim kho qhov cuam tshuam ntawm qhov kub thiab txias.
Q: Thaum twg koj yuav tsum siv ASTM A350 LF2 hloov ASTM A105?
A: Koj yuav tsum siv ASTM A350 LF2 thaum ua haujlwm cov kav dej hauv sub- xoom ib puag ncig mus rau -46℃(-50℃F), raws li LF2 yuav tsum tau kuaj Charpy V-notch cuam tshuam ntawm qhov kub thiab txias, qhov A105 tsis lav qhov kub-kub toughness.
Q: Vim li cas carbon steel tawg tom qab vuam yog tsis preheated?
A: Cov cua txias nrawm nrawm khov cov roj hydrogen hauv cov hlau vuam thiab tsim cov txheej txheem martensitic nyuaj hauv HAZ, ua rau muaj kev ntxhov siab sab hauv thiab txias tawg.
Q: ASTM A105 puas tuaj yeem siv rau kev siv roj qaub (H2S)?
A: Tsuas yog tshwj xeeb xaj raws li NACE- ua raws (ASTM A105N nrog kev tswj nruj nruj hauv qab 227 HRC) kom tiv thaiv sulfide kev nyuaj siab tawg. Txuj A105 tsis raug ntsuas rau kev pabcuam qaub.
Q: Qhov siab tshaj plaws ua haujlwm kub rau ASTM A105 yog dab tsi?
A: Raws li ASME B16.5 thiab B16.11 cov lus qhia, ASTM A105 Cheebtsam tuaj yeem siv mus txog 427℃(800℃F), txawm hais tias lub sijhawm ntev tshaj li 425℃ua rau muaj kev pheej hmoo ntawm steel graphitization.
Q: Vim li cas forged fittings kav ntev dua cam khwb cia fittings?
A: Forging muab:
- Cov nplej zoo dua
- Siab zog tiv taus
- Kev pheej hmoo qis dua
Rau cov tshuab siab, forged A105 fittings yog nyiam.
