API 5L carbon steel yeeb nkabyog ib qho seamless lossis welded steel yeeb nkab ua raws li American Petroleum Institute (API) 5L specification thiab feem ntau yog siv rau kev thauj mus los ntawm roj, roj thiab dej. PSL 1 yog ib qib hauv API 5L specification, uas txhais tau hais tias cov khoom siv kho tshuab thiab cov khoom siv ntawm cov yeeb nkab ua tau raws li thawj theem ntawm API 5L specification. API 5L PSL 2 GR.B carbon steel kav muaj nyob rau hauv qhov ntau thiab tsawg ntawm 1/2 "mus rau 48" NB (nominal bore inch) thiab nyob rau hauv specifications ntawm Sch 10 txog XXS (muaj zog ntxiv). Lub zog tawm los ntawm cov kav hlau no yog qhov tsawg kawg nkaus ntawm 245MPa (35,500 psi) thiab qhov siab tshaj plaws ntawm 450MPa (65,300 psi), nyob ntawm qib.
API 5L specifications standardize pipeline transport systems for the natural gas and oil industries and are widely applicable to the transport of gas, roj, thiab dej. X42, API 5L kab yeeb nkab yog siv los tsim tag nrho cov kav dej, tsis zoo li casing thiab tubing.
Cov pa roj carbon steel API 5L kab yeeb nkab muaj cov yam ntxwv ntawm lub zog siab, rov siv tau dua, cov phab ntsa tuab, kev tiv thaiv corrosion, lub neej ua haujlwm ntev thiab ua tiav cov txheej txheem.
GNEE muaj cov pa roj carbon steel api 5l x42, x52, x60, x65 thiab x70 kab yeeb nkab nyob rau hauv ntau qhov ntev, sab nraud diameters, sab hauv diameters, qhov ntau thiab tsawg thiab phab ntsa thicknesses kom tau raws li qhov project xav tau. API 5L specification yeeb nkab txawv nyob rau hauv ntau txoj kev los ntawm cov ntaub ntawv siv nyob rau hauv lwm yam specifications. Qhov tsawg kawg nkaus lub zog ntawm API 5L carbon steel yeeb nkab yog 485MPa. Cov khoom tseem ceeb ntawm API 5L carbon steel kav yog carbon thiab manganese, thiab cov hlau tseem muaj 0.15% Nb, V thiab Ti. Cov muaj pes tsawg leeg ntawm API 5L PSL1 yeeb nkab txhim khu nws cov khoom weldability.
