FAQ
API 5L X52 sib npaug li cas?
Hauv cov qauv thoob ntiaj teb, qib steel sib haum rau API 5L X52 yogL360; Raws li ob qho tib si sib piv cov txiaj ntsig kev xav tau lub zog (Ntau dua lossis sib npaug rau 360 MPa), lawv ua haujlwm raws li kev lees paub thoob ntiaj teb sib npaug.
Qhov ntsuas siab ntawm API 5L X52 yeeb nkab yog dab tsi?
Lub siab -cov kabmob muaj peev xwm ntawm API 5L X52 steel yeeb nkab nyob ntawm nws txoj kab uas hla thiab phab ntsa tuab; tus qauv nws tus kheej tsis ncaj qha qhia cov nqi siab tshwj xeeb. Raws li API 5L specification, qhov tsawg kawg nkaus yield zog ntawm X52 steel yeeb nkab yog 360 MPa (kwv yees li 52,220 psi); Kev siv qhov ntsuas no ua ke nrog qhov tshwj xeeb qhov ntev, nws qhov theoretical sab hauv siab lub zog tuaj yeem suav nrog siv Barlow's Formula.
