API 5L X42 welded steel yeeb nkab qhia tau zoo heev kev pab cuam efficiency thiab durability nyob rau hauv lub zog kis tau tus mob, ua tsaug rau nws balanced mechanical zog thiab optimized manufacturing txheej txheem. Raws li cov khoom lag luam qib pib raws li API tus qauv, X42 ua tiav lub zog ntawm 290 MPa thiab lub zog tensile ntau ntawm 415-655 MPa. Ua ke nrog tus qauv kev tswj hwm nruj ntawm cov tshuaj muaj pes tsawg leeg (carbon sib npaug tsawg dua lossis sib npaug li 0.25%), nws tuav Charpy cuam tshuam lub zog ntau dua 27J txawm nyob rau ntawm -20 degree, ua tau raws li cov kev cai ua haujlwm rau nruab nrab thiab qis-siab ntuj xa mus rau hauv chav kawm II thiab III onshore regions.

Dab tsi yog API 5L X42 cov khoom sib npaug
API 5L X42 cov ntaub ntawv sib npaug yog feem ntau txhais los ntawm lawv qhov tsawg kawg nkaus tawm lub zog (290 MPa lossis 42 ksi) thiab suav nrog EN 10208-2 L290NB, ISO 3183 L290, thiab GB / T 9711 L290, nrog ASTM A106 Gr. B thiab A53 Gr. B kuj suav tias yog lwm txoj hauv kev rau qee yam kev siv, txawm hais tias lawv yog cov qauv sib txawv rau seamless (A106) thiab kev siv dav dav (A53) kav.
