API 5L X65 PSL 2 Kab Pipes
API 5L X65 PSL2 Kab Pipesyog siab - lub zog carbon steel kav tsim raws li API Spec 5L tus qauv. Lawv feem ntau yog siv rau hauv kev lag luam roj av thiab cov nkev roj rau kev ua haujlwm ntev - nrug, siab - kev thauj mus los ntawm cov kua dej. "X65" txhais tau hais tias qhov tsawg kawg nkaus yield zog ntawm65,000 psi (450 MPa), thaum lub npe "PSL2" sawv cev rau cov khoom lag luam nruj dua.
Qhov no suav nrog qhov yuav tsum tau ntsuas qhov ntsuas qhov hnyav thiab kev txwv nruj ntawm cov tshuaj muaj pes tsawg leeg (xws li cov pa roj carbon sib npaug) kom ntseeg tau zoo dua weldability thiab kev nyab xeeb hauv ib puag ncig hnyav xws li siab - kev sib kis, cov kav dej hauv qab dej, lossis kev pabcuam qaub.
Kev nruj nruj raws li PSL2 cov qauv cuam tshuam.Nyem qhov no mus thov tus qauv MTR rau peb qhov tseeb X65 PSL2 batch.
