Mae pibellau wedi'u weldio â sêm syth yn cael eu gwneud o ddur stribed. Gelwir y pibellau a geir trwy weldio sêm syth ar offer weldio amledd uchel yn bibellau wedi'u weldio â sêm syth. (Fe'i enwir oherwydd bod uniad weldio y bibell ddur yn ffurfio llinell syth) Enw safonol pibell weldio sêm syth yw pibell ddur wedi'i weldio ar gyfer cludo hylif pwysedd isel. O'i gymharu â phibellau weldio cyffredin, mae prawf pwysedd dŵr ychwanegol. Mae pris pibellau hylif pwysedd isel ychydig yn uwch na phibellau weldio sêm syth arferol.
