PSL sawv cev rau dab tsi? PSL yog lub ntsiab lus rau "Product Specification Level" thiab yog ib qho tseem ceeb ntawm API 5L kab yeeb nkab qauv. Qhov kev qhia tshwj xeeb no qhia txog qhov nruj ntawm cov kev cai uas cov raj xa dej yuav tsum tau ua, nrog PSL2 yog siab dua ntawm ob qib uas tau teev tseg hauv tus qauv. Kev nkag siab lub ntsiab lus no yog qhov tseem ceeb rau cov kws tshaj lij hauv kev lag luam pipeline vim nws ncaj qha ntsig txog qhov zoo thiab kev ua tau zoo ntawm cov kab yeeb nkab siv hauv cov phiaj xwm tseem ceeb.
Cov khoom tshwj xeeb theem ntawm cov yeeb nkab kab tau muab faib ua PSL1 thiab PSL2, lossis qib zoo tau muab faib ua PSL1 thiab PSL2.
PSL2 siab dua PSL1. Ob qhov kev qhia tshwj xeeb no tsis tsuas yog sib txawv hauv kev tshuaj ntsuam xyuas, tab sis kuj tseem muaj cov tshuaj lom neeg thiab cov khoom siv kho tshuab. Yog li ntawd, thaum txiav txim raws li API 5L, cov nqe lus nyob rau hauv daim ntawv cog lus yuav tsum qhia cov khoom specification theem, piv txwv li PSL1 los yog PSL2, nyob rau hauv tas li ntawd mus rau lub niaj zaus ntsuas xws li specifications thiab steel qib.
PSL2 yog nruj dua PSL1 nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, tensile zog, cuam tshuam lub zog, tsis-destructive kuaj thiab lwm yam ntsuas. PSL1 tsis tas yuav muaj kev sim tsis muaj kev puas tsuaj, tab sis PSL2 yuav tsum tsis txhob muaj kev puas tsuaj ntawm txhua ceg.
