FAQ
Lub zog ntawm X60 steel yog dab tsi?
Qhov tsawg kawg nkaus yield zog ntawm API 5L X60 steel yog 415 MPa (kwv yees li 60 kpsi), thiab lub zog tensile siab tshaj los yog sib npaug rau 520 MPa. Nws yog lub siab -lub zog pipeline steel dav siv nyob rau hauv siab - siab xa mus rau cov kav dej xws li roj thiab cov nkev.
Dab tsi yog qhov txawv ntawm API 5L X60 thiabX65?
API 5L X65 muaj lub zog siab dua thiab kev ua haujlwm nruj dua li X60, ob qho tib si yog siab - lub zog kav hlau, tab sis X65 yog qhov tsim nyog rau kev siab dua thiab ntau qhov kev pabcuam nyuaj.
