OD: 6-720MM
WT: 0.5-120MM
Hyd: 3-16M
Cais: Petroliwm, Peirianneg Gemegol, Trydan, Boeler
Safon: ASTM A335 / A335M, ASTM A213 / 213M, DIN17175-79, JIS3467-88, GB5310-95

Mae pibell aloi yn fath o bibell ddur di-dor, mae ei berfformiad yn llawer uwch na pherfformiad pibell ddur di-dor cyffredinol, oherwydd bod y math hwn o bibell ddur yn cynnwys mwy o Cr, ei wrthwynebiad tymheredd uchel, ymwrthedd tymheredd isel, mae perfformiad ymwrthedd cyrydiad yn llawer gwell nag eraill Pibell ddur, felly defnyddir y bibell aloi yn eang mewn petrolewm, awyrofod, cemegol, pŵer trydan, boeler, milwrol a diwydiannau eraill.
