Disgrifiad o'r Cynnyrch EN 10210/S355 Pibell Dur Di-dor
Mae gan bibell ddur S355 berfformiad weldio da, plastigrwydd, caledwch a thechnoleg prosesu, ymwrthedd cyrydiad da, cryfder uchel a thymheredd pontio critigol isel oer a brau. Gall defnyddio dur aloi cryfder uchel isel leihau pwysau'r strwythur yn effeithiol, gwella cryfder ac anystwythder y strwythur, a gwella gwydnwch wrth leihau trwch y strwythur. Defnyddir pibellau dur di-dor S355 yn gyffredin wrth gynhyrchu pontydd, llongau, offer gorsaf bŵer, peiriannau codi a chludo, gweithgynhyrchu peiriannau a rhannau strwythurol peirianneg a weldio eraill sy'n dwyn llwythi uwch.
