API Spec 5L PSL2 X70 (L485) Pipeline Steel Phaj
Zoo weldability ntawm steel yog qhov tseem ceeb los xyuas kom meej qhov kev ncaj ncees ntawm cov raj xa dej thiab qhov zoo ntawm qhov chaw vuam. Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm kev txhim kho cov kav dej niaj hnub no yog qhov txo qis ntawm cov ntsiab lus carbon hauv cov hlau txuas ntxiv. Nrog rau kev txo qis ntawm cov ntsiab lus carbon, lub weldability ntawm steel tau zoo heev.
