A671 khoom yog dab tsi?
ASTM A671 GR.CC 60 steel yeeb nkab yog siab -lub zog carbon-manganese-silicon steel hluav taws xob- fusion-welded yeeb nkab siv hauv cov kav dej tshwj xeeb, tsim nyog rau kev ua haujlwm uas muaj qee yam kev kub ntxhov thiab kub.
Kev siv (feem ntau yog "executive (ntawm no yog xa mus rau tus qauv rau kev ua)" hauv qhov no (pipe- cuam tshuam) cov ntsiab lus, tab sis "kev nqis tes ua" kuj tuaj yeem nkag siab hauv qhov dav; lo lus meej dua ntawm no tuaj yeem yog "tsim" lossis yooj yim "ua tiav (raws li tus qauv)", tab sis rau cov qauv txhais lus peb feem ntau siv "hais los ntawm" los ntawm "hais txog" qhov tseeb nyob rau hauv tus qauv terminology) txheem rau ASTM A671 GR.CC 60 yogHluav taws xob-Fusion-Welded Steel Pipe rau Atmospheric thiab Lower Temperatures (A671), uas yog hom welded steel yeeb nkab (EFW ncaj-seam steel yeeb nkab).
"GR" sawv cev rau "qib". "CC 60" qhia cov khoom qib ntawm cov yeeb nkab steel. Ntawm no, "CC" yog cov khoom siv code, feem ntau sawv cev rau carbon-manganese-silicon steel, uas muaj lub zog zoo thiab tawv. "60" tuaj yeem cuam tshuam rau cov khoom siv kho tshuab xws li lub zog tawm los ntawm cov khoom siv. Nws sawv cev rau qhov tsawg kawg nkaus yield zog (nrog rau chav tsev yuav yog ksi; 1 ksi=6.895 MPa), kwv yees li sib npaug rau lub zog tawm ntawm ib ncig ntawm 414 MPa.
Dab tsi yog astm a671 gr cc60 sib npaug
Thawj qhov sib npaug rau ASTM A671 Gr. CC60 yog ASTM A516/A516M Qib 60, zoo- nplej, tua cov pa roj carbon steel phaj siv rau cov hlab ntsha siab, nrog A671 CC60 yog cov khoom siv hluav taws xob Fusion Welded (EFW) yeeb nkab, tsim rau siab -siab, qis- qhov kub thiab txias.
