Nco tseg: PSL2 txwv kev txwv ntawm ob qho tib si lub zog siab tshaj plaws thiab lub zog tensile siab tshaj plaws (nrog rau kev txwv siab ntawm 450 MPa thiab 655 MPa raws li), ua kom cov khoom muaj peev xwm deformation yas txaus thiab muaj kev nyab xeeb dua.
Kev ua tau zoo welding zoo (qhov yuav tsum tau muaj rau cov kav dej hlau)
Qhov qis carbon sib npaug tsim ntawm API 5L Gr.B ua kom cov vuam ua tau zoo, uas yog qhov yuav tsum tau ua rau loj - nplai kev tsim kho ntawm cov kav dej hlau. PSL2 qib yuav tsum muaj cov pa roj carbon sib npaug (CEIIW) Tsawg dua lossis sib npaug ntawm 0.43 thiab Pcm Tsawg dua lossis sib npaug li 0.25, kom ntseeg tau tias muaj zog thiab tiv taus txias tawg hauv tshav kub- thaj tsam cuam tshuam hauv thaj chaw vuam.
Cov ntsiab lus tseem ceeb Welding:
• Tsawg tus nqi CE:
Ua tau zoo txo qhov nyiam ntawm vuam cua sov- thaj tsam cuam tshuam kom tawv thiab txo qhov kev pheej hmoo ntawm cov kab mob khaub thuas
• Tsawg- phom sij- ntsiab lus:
S Tsawg dua los yog sib npaug rau 0.030% (PSL1) / Tsawg dua lossis sib npaug li 0.015% (PSL2), kom ntseeg tau cov purity ntawm welds thiab cov hlau puag
• Haum rau ntau txoj kev vuam:
taub qab vuam ntawm seamless steel kav, submerged arc vuam ntawm kauv / ncaj seam welded kav, thiab lwm yam., nrog zoo teb nplhaib vuam kev ua tau zoo
Rau qib PSL1, qhov txwv sab saud ntawm cov ntsiab lus carbon yog qhov dav (tsawg dua lossis sib npaug li 0.26%), thiab preheating ntawm 100-150℃raug pom zoo thaum vuam; rau qib PSL2, cov pa roj carbon ntsiab lus yuav tsum nruj dua (tsawg dua lossis sib npaug ntawm 0.16-0.18%), ua rau muaj kev sib txuas zoo dua thiab feem ntau tsis xav tau tshwj xeeb preheating lossis tsuas yog xav tau qis dua preheating.
Zoo qis -kub toughness thiab tsis kam rau kev ua haujlwm tawg tawg
API 5L Gr.B PSL2 yuav tsum tau Charpy V-kev ntsuas kev cuam tshuam los xyuas kom meej cov khoom tiv thaiv kom tawg tawg nyob rau hauv qis- qhov kev pabcuam kub. Qhov zoo-grained microstructure tau los ntawm normalization lossis TMCP cov txheej txheem txhim kho cov khoom qis- qhov kub thiab txias, ua rau Gr.B pipeline steel tuaj yeem siv tau rau hauv cov cheeb tsam txias thiab ib puag ncig nrog lub caij kub hloov pauv loj.
Yam cuam tshuam toughness Performance index (PSL2):
• Kev ntsuas kub: Feem ntau -20℃lossis qis dua (raws li tus neeg siv yuav tsum tau ua)
• Yam tsawg kawg nkaus lub zog: Ntau dua lossis sib npaug ntawm 27 J (tus nqi nruab nrab) / Ntau dua lossis sib npaug rau 20 J (tus nqi ib leeg)
Zoo corrosion kuj thiab ib puag ncig adaptability
API 5L Gr.B nthuav tawm zoo tiv thaiv corrosion tsis zoo nyob rau hauv ib txwm atmospheric, dej tshiab, av, thiab roj thiab gas media. Rau qhov chaw ua haujlwm acidic (muaj H₂S), cov ntaub ntawv tshwj xeeb uas tau teev tseg hauv Cov Ntawv Ntxiv J ntawm API 5L PSL2 (acid-cov kav dej) yuav tsum raug xaiv, nrog rau kev tswj ntxiv ntawm cov ntsiab lus sulfur, hardness, thiab HIC tsis kam.
Rau ib puag ncig marine, Appendix H thiab Appendix J ntawm PSL2 muab cov khoom siv ntxiv uas yuav tsum tau siv rau cov kav dej sab nrauv thiab cov kav dej hauv qab.
Zoo txias khoov thiab kev ua haujlwm zoo
