ERW vs. LSAW ntawm X52 Qib: Yam Koj Xav Tau
Tus naj npawb ceeb ntawm kev nug rau "X52 yeeb nkab" qhia txog lub cheeb uas tsis muaj nyob rau hauv cov txheej txheem vuam tus neeg yuav khoom xav tias:
- ERWyog tus qauv, kev lag luam feem ntau rau X52 los ntawm1/2 "mus txog 24" OD. Yog tias koj cov kab poob rau hauv qhov ntau, ERW yuav luag txhua lub sijhawm hu xov tooj tshwj tsis yog tias qhov project spec qhia meej meej cais nws.
- LSAW(tseem hu ua JCOE) yuav siv sij hawm ntau dua rau qhov loj dua, feem ntau16 "mus txog 56" +, tsim los ntawm phaj es tsis yog coil.
- SSAW/HSAW(spiral welded) npog qhov loj zoo sib xws - txoj kab uas hla ntau thiab qee zaum muaj qhov qis dua - tus nqi hloov pauv rau LSAW rau qis dua - cov kab dej los yog roj, txawm hais tias nws tsis tshua tau teev tseg rau cov roj / roj cov kab tseem ceeb.
Yog tias koj qhov project nyob hauv thaj tsam 16 "–24" sib tshooj, qhov kev xaiv feem ntau yog los ntawm qhov project specification, chav kawm siab, thiab zeb ua lub sij hawm es tsis yog cov khoom siv zog - ob qho tib si cov txheej txheem ua tau raws li X52 txhua yam yuav tsum tau ua thaum tsim nyog.
Qib Qib: PSL1, PSL2, thiab Kev Xa Khoom
X52 muaj nyob rau ntawm ob theem khoom tshwj xeeb uas tau teev tseg los ntawm API 5L:
- PSL1- theem pib. Kev ntsuas tshuaj lom neeg thiab cov khoom siv kho tshuab, xa "raws li dov" (kev xa khoom R). Haum rau feem ntau ntawm cov uas tsis yog - tseem ceeb hauv kev sib sau ua ke thiab faib cov ntawv thov.
- PSL2- ntxiv qhov yuav tsum tau Charpy V- ntsuas qhov cuam tshuam, txwv nruj dua ntawm cov ntsiab lus sulfur thiab phosphorus, thiab 100% tsis yog- kuaj xyuas txhua qhov ntev. PSL2 yeeb nkab yog muab nyob rau hauv kev xa khoom N (normalized), Q (quenched thiab tempered), los yog M (thermomechanically dov) - cov no tsis yog cov ntawv sib hloov, lawv muaj kev cuam tshuam cov cua kub sib txawv- txoj kev kho mob uas cuam tshuam rau qhov toughness thiab thaj chaw weldability.
Rau kev pabcuam qaub (H2S), tsis yog PSL1 lossis tus qauv PSL2 tau txais kev pabcuam. Koj xav tau cov kua qaub- pabcuam kev pabcuam - X52NS, X52QS, lossis X52MS - tau xaj thiab sau tseg rau NACE MR0175 / ISO 15156. Qhov no yuav tsum tau thov kom meej meej; Nws tsis yog hais los ntawm kev xaj "PSL2."
Dimensional thiab Test Reference
- OD ntau (ERW):1/2 "mus rau 24" (21.3mm-610mm)
- Phab ntsa thickness:feem ntau hais raws li Sch STD los ntawm Sch XXS, qhov loj me rau koj qhov siab tshaj plaws kev ua haujlwm siab (MAOP) es tsis yog xaiv los ntawm lub sijhawm ua haujlwm.
- Ntev:ib qho random ntev (SRL, kwv yees li 5-7 m) lossis ob qhov ntev (DRL, kwv yees li 11-13 m); taag ntev muaj los ntawm kev txiav txim
- Kev npaj kawg:Plain kawg (rau teb bevel/fit-up) los yog Hoobkas-beveled kawg rau ncaj khi- hauv vuam
- Yuav tsum tau kuaj:100% hydrostatic test, weld seam ultrasonic soj ntsuam, thiab tshuaj lom neeg / tshuaj ntsuam xyuas ib lub tshav kub
- Common coatings:liab qab / kua roj vanish rau saum - hauv av los yog luv - lub sij hawm cia; FBE lossis 3- txheej PE (3LPE) rau kev pabcuam faus; txheej txheej xaiv yuav tsum ua raws li cov av thiab tsim-lub neej yuav tsum tau, tsis yog generic default
Cov lus nug nquag nug (FAQ)
Q: Puas yog X52 ERW yeeb nkab muaj zog li X52 LSAW yeeb nkab?
A: Yog lawm, thaum ob qho tib si raug tsim thiab sim rau API 5L - qib kev xaiv (X52/L360) lav qhov tsawg kawg nkaus yield thiab tensile lub zog tsis hais txog cov txheej txheem vuam. Qhov sib txawv ntawm qhov sib txawv yog muaj nyob rau hauv txoj kab uas hla: ERW sab saum toj tawm ib ncig ntawm 24 ", thaum LSAW yog txoj hauv kev rau cov yeeb nkab loj.
Q: Qhov txawv ntawm PSL1 thiab PSL2 X52 yeeb nkab yog dab tsi?
A: PSL1 suav nrog cov tshuaj lom neeg thiab kev sim tshuab. PSL2 ntxiv qhov yuav tsum tau muaj kev cuam tshuam rau kev sim siab (Charpy V-notch), kev txwv nruj dua ntawm cov khoom seem xws li sulfur thiab phosphorus, thiab 100% tsis yog -kev ntsuas kev puas tsuaj ntawm txhua qhov kav dej ntev - siv qhov twg cov raj xa dej ua rau qhov tsis ua haujlwm, qhov kub thiab txias, lossis qhov project specifications xav tau ntxiv.
Q: Kuv puas tuaj yeem xaj X52 rau kev pabcuam roj qaub?
A: Tsuas yog los ntawm kev qhia cov qaub- kev pabcuam (X52NS, X52QS, lossis X52MS) nrog NACE MR0175/ISO 15156 cov ntaub ntawv ua raws li kev yuav khoom. Standard X52, txawm nyob ntawm PSL2, tsis tau ntawv pov thawj rau H2S- muaj kev pabcuam tshwj tsis yog qhov no tau txiav txim meej.
Q: Dab tsi loj npaum li cas kuv yuav tsum tau txais los ntawm ERW vs. LSAW rau X52?
A: ERW feem ntau npog 1/2 "mus rau 24" OD; LSAW khaws los ntawm kwv yees li 16 "thiab txuas ntxiv dhau 56". Hauv 16 "–24" sib tshooj, cov txheej txheem ib txwm tuaj yeem ua tau raws li qib yuav tsum tau ua - qhov kev txiav txim siab feem ntau yog los ntawm qhov project specification thiab zeb muaj.
