X42 seamless pipeline yeeb nkab yog ib hom yeeb nkab steel tshwj xeeb tsim los thauj cov kua dej xws li roj thiab roj. Tsim los ntawm cov txheej txheem seamless, nws muaj lub zog siab thiab zoo sealing kev ua tau zoo. Qhov kev xaiv "X42" qhia tias nws qhov tsawg kawg nkaus yield zog ntawm 42,000 psi (kwv yees li 290 MPa), faib nws raws li cov khoom qib hauv API 5L tus qauv.
Cov khoom siv ntawm X42 seamless pipeline yeeb nkab ua tau raws li qhov yuav tsum tau ua ntawm API 5L. Nws lub zog tawm los tsis pub tsawg dua 290 MPa, nrog lub zog tensile ntawm 415 thiab 760 MPa. Lub elongation feem ntau tshaj 20%, ua kom pom qhov zoo ductility. Qhov kev sib xyaw ua ke ntawm cov khoom no ua rau X42 seamless pipeline yeeb nkab ua tau zoo hauv ntau yam kev xav tau kev ua haujlwm.
