Incazelo emfushane:
Ipayipi Elingenamthungo Lensimbi Engagqwali engu-347: Ukumelana Nokushisa Okuphezulu Nokuvikelwa Kokugqwala.
Ukuhlolwa Kokuhluzeka Kwepayipi Lensimbi Engagqwali:
Amapayipi Angenamthungo Ensimbi Engagqwali angu-347 enziwe ngensimbi engagqwali ezinzile, eklanyelwe ukunikeza ukumelana okuhle kakhulu nokugqwala kwe-intergranular, ikakhulukazi ezindaweni ezishisa kakhulu. Lawa mapayipi afaneleka kakhulu ekusetshenzisweni okudinga amandla aphezulu okuhamba kanye nokumelana ne-oxidation, njengasekucutshungulweni kwamakhemikhali, ukukhiqizwa kwamandla, kanye nezinhlelo zokukhipha umoya ezishisa kakhulu. Nge-niobium eyengeziwe, insimbi engagqwali engu-347 inikeza ukuzinza okuthuthukisiwe, ivimbela ukuna kwe-carbide futhi igcine amandla ayo emazingeni okushisa afinyelela ku-1500°F (816°C). Lokhu kwenza amapayipi angenamthungo ensimbi engagqwali angu-347 afanelekele izindawo ezidinga ukuqina kanye nokuthembeka kwesikhathi eside.
