Pibell Dur Di-dor A333 A335
ASTM A333 yw'r fanyleb safonol ar gyfer pibellau carbon a dur aloi di-dor a weldio ar gyfer cymwysiadau cryogenig. Mae'r safon yn cwmpasu sawl gradd o bibell ddur: Gradd, Gradd 3, Gradd 4, Gradd 6, Gradd 7, Gradd 8, Gradd 9, Gradd 10 a Gradd 11. Mae ASTM A335 yn bibell enwol dur aloi ferritig di-dor ar gyfer defnydd tymheredd uchel. Defnyddir yn bennaf ar gyfer gwresogi pibellau wyneb boeleri pwysedd isel a chanolig (yn gyffredinol nid yw pwysau gweithio yn fwy na 5.88Mpa, mae tymheredd gweithio yn is na 450 gradd); a ddefnyddir mewn boeleri pwysedd uchel (mae pwysau gwaith yn gyffredinol yn uwch na 9.8Mpa, mae tymheredd gweithio rhwng 450 gradd -650 gradd) Pibellau arwyneb gwresogi, economizers, superheaters, reheaters, pibellau diwydiant petrocemegol, ac ati.
