API 5L LSAW Kab Yeeb Nkab Cov Khoom Qhia
API 5L LSAW Kab Yeeb Nkab yog tsim los rau siab - siab kis tau tus mob ntawm cov roj, nkev roj, ntau -phase kua, thiab siab - ntws slurry hla cov kav dej loj. Tsim los ntawm longitudinal submerged arc vuam-feem ntau yog siv JCOE lossis UOE txoj hauv kev ua haujlwm- cov kav dej hnyav no xa cov qauv sib xws, nruj qhov ntev ntev, thiab siab Charpy V- qhov cuam tshuam toughness hla 5 ntiv tes sab nraud. Muaj nyob rau hauv PSL1 thiab PSL2 specifications rau onshore thiab offshore zog infrastructure.
