API 5L X52yog lub raj xa dej qib steel nrog qhov tsawg kawg nkaus tawm lub zog ntawm 52,000 psi (kwv yees li 358 MPa), dav siv hauv cov kav dej rau kev thauj cov dej xws li roj thiab cov nkev.
Cov yeeb nkab steel no yog ib qho ntawm cov qib tseem ceeb hauv API 5L thoob ntiaj teb tus qauv tsim los ntawm American Petroleum Institute (API). "X" sawv cev rau Pipeline Steel, thiab "52" qhia tias nws qhov tsawg kawg nkaus yield zog ntawm 52 txhiab phaus ib square inch (ksi), sib npaug rau 358 megapascals (MPa). Nws feem ntau yog ua los ntawm qis-carbon lossis qis- alloy steel, muaj lub zog zoo, toughness, thiab weldability, ua rau nws haum rau ntev - kev thauj mus los nyob rau hauv qhov chaw nruab nrab mus rau qhov kub siab.
API 5L X52cov yeeb nkab steel tau muab faib ua ob qib zoo: PSL1 thiab PSL2.
PSL1yog cov khoom tsim tshwj xeeb qib, haum rau kev ua haujlwm dav dav;
PSL2muaj cov kev cai nruj dua, xav tau kev tswj xyuas nruj dua ntawm cov tshuaj muaj pes tsawg leeg, cuam tshuam rau lub zog (piv txwv li, Charpy cuam tshuam lub zog Ntau dua lossis sib npaug ntawm 40J ntawm -20 degree), thiab cov pa roj carbon sib npaug (Ceq Tsawg dua lossis sib npaug rau 0.43%) kom ntseeg tau zoo heev weldability thiab qis-kub tawg tsis kam.

FAQ
Qhov txawv ntawm API 5L Qib B thiab API 5L X52 yog dab tsi?
API 5L Qib B: Feem ntau yog siv rau cov kav dej thauj cov pa roj, dej, thiab roj, qhov twg cov kev cai tsis nruj dhau ntawm cov khoom siv tshuab. API 5L X52: Siv nyob rau hauv cov kav dej uas yuav tsum tau muaj zog dua thiab muaj zog, tshwj xeeb tshaj yog rau cov kav dej thiab cov kav dej sib sib zog nqus.
API 5L X52 sib npaug li cas?
Raws li tshuaj muaj pes tsawg leeg, txhua yam khoom thiab lwm yam kev sib piv cov ntaub ntawv, API 5L X52 sib npaug phaj khoom yogL360 hlau, uas feem ntau yog ua rau L360 steel daim hlau los yog L360 steel kav siv nyob rau hauv cov roj av thiab roj kev lag luam rau pipeline tsheb thauj mus los.
X52 yeeb nkab siv rau dab tsi?
