L360 PSL2 muaj lub zog tawm los ntawm 360MPa txog 510MPa. Tshwj xeeb, qhov kev xav tau lub zog ntawm L360 PSL2 yog nyob nruab nrab ntawm 360MPa thiab 510MPa, thiab lub zog tensile yuav tsum yog ntawm 460MPa thiab 760MPa. Lub elongation yog 20%, thiab qhov cuam tshuam lub zog ntawm 0 degree yog ntau dua los yog sib npaug rau 40J.
PSL2 qib API 5L L360 cov kav dej muaj zog ntau dua. Vim yog kev siv cov txheej txheem ntau lawm thiab kev tswj kom zoo, xws li kev tswj xyuas cov tshuaj muaj pes tsawg leeg, kev kho kom zoo dua qub lossis kev kho cua sov, cov nplej loj ntawm cov yeeb nkab yog finer thiab cov qauv zoo sib xws, yog li kev txhim kho lub zog.
Hauv cov ntawv thov, L360 PSL2 seamless steel kav feem ntau siv rau kev thauj mus los ntawm cov kua xws li roj, roj, thiab dej. Lawv lub zog tawm los ua kom muaj zog ua rau lawv tuaj yeem tiv taus ntau dua, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem kev thauj mus los. Piv txwv li, nyob rau hauv ib co high-pressure natural gas kis pipelines, L360 PSL2 steel kav yuav ua hauj lwm ruaj khov nyob rau lub sij hawm ntev nyob rau hauv ib tug hnyav ib puag ncig tej yam kev mob, zoo tiv thaiv kev huam yuaj xws li rupture thiab leakage ntawm pipelines vim tsis muaj zog, thiab txo cov kev pheej hmoo ntawm deformation. los yog rupture ntawm pipelines vim lub zog tsis txaus, yog li ua kom muaj kev nyab xeeb kev thauj mus los ntawm lub zog.
