API 5L X65 yog lub zog siab, qis-alloy pipeline steel feem ntau siv hauv cov kav dej thiab roj. Cov hlau no tshwj xeeb tshaj yog tsim rau cov xwm txheej huab cua uas yuav tsum tau muaj kev kub siab thiab kub siab, thiab tseem muaj zog seawater corrosion kuj kom ntseeg tau tias kev thauj mus los ntev ntawm cov kav dej. Lub zog yield thiab tensile lub zog ntawm API 5L X65 tsis tsawg dua 450MPa thiab 535MPa feem, thiab nws kuj muaj kev vuam zoo.
