Dab tsi yog qhov txawv ntawm API 5L X60 thiabX65?
Qhov sib txawv tseem ceeb ntawm API 5L X60 thiab X65 yog nyob rau hauv qib zog thiab siv tau rau kev ua haujlwm: X60 muaj qhov tsawg kawg nkaus tawm lub zog ntawm 415 MPa (60000 psi), thaum X65 muaj qhov tsawg kawg nkaus yield zog ntawm 450 MPa (65000 psi). X65 muaj lub zog ntau dua thiab tsim nyog rau cov phiaj xwm kev thauj mus los roj thiab roj nrog kev siab dua thiab ntau dua geological tej yam kev mob.
