Dab tsi yog API 5L X42 PSL1 PSL2 YEEB
Lub npe ntawm X42 Seamless Pipeline cov yeeb nkab ua raws API 5L tus qauv. "X" qhia tias cov raj raj dej raj yog ua los ntawm cov hlau, thiab "42" sawv cev rau nws cov xwm txheej tsawg kawg (KSI), uas yog kwv yees li 290 MPa hauv cov koog. Tus qauv steel no yuav tsum tau cov yeeb nkab hlau kom muaj cov weldability thiab formability thaum ua kom tau raws li kev tsim kho lub zog ntawm kev ua haujlwm ntev} kev deb npaum li cas.
