ASTM A252 Kauv Welded Steel Pipes
Nws qhov txiaj ntsig zoo ntawm kev ruaj khov vuam zoo, kev ua haujlwm siab vuam, tsis muaj lub teeb pom kev zoo, thiab cov pa luam yeeb tsawg ua rau nws txoj kev vuam tseem ceeb hauv kev tsim cov hlau tseem ceeb xws li cov hlab ntsha, cov yeeb nkab, cov kab teeb thiab kab. Nyob rau hauv xyoo tsis ntev los no, txawm hais tias muaj ntau yam tshiab high-efficiency thiab high-zoo welding txoj kev tau tshwm sim ib tug tom qab lwm, daim ntawv thov teb ntawm submerged arc vuam tsis tau cuam tshuam. Los ntawm qhov kev xav ntawm qhov kev faib ua feem ntawm qhov hnyav ntawm cov hlau tso rau hauv ntau txoj kev fusion welding, submerged arc vuam nyiaj li ntawm 10%, uas tsis tau hloov ntau xyoo.
