Incazelo emfushane:

I-molybdenum (TZM) yokubhoboza i-mandrel iyingxenye ebalulekile esetshenziswa ezinqubweni zokwenza insimbi yokushisa okuphezulu. Ivamise ukwenziwa ngengxubevange ye-molybdenum (TZM alloy), enamandla amakhulu ezinga lokushisa eliphezulu nokumelana ne-oxidation. I-mandrel yokubhoboza isetshenziswa ngokuyinhloko ekuqhumeni kwensimbi yesithando somlilo ukushaya umoya-mpilo esithandweni somlilo ukuze kuthuthukiswe i-oxidation nokuxubana kwensimbi. Ukuzinza kwezinga lokushisa eliphezulu nokumelana nokugqwala kwama-mandrels abhobozayo e-molybdenum (TZM) kuwenza abe yingxenye ebalulekile enqubweni yokwenza insimbi.
