ASME SA 387 GRADE 11 Icyiciro cya 2 ibyuma

Nkicyuma cyumuvuduko wicyuma kugirango ukoreshwe muri serivisi yubushyuhe bwo hejuru, ukoreshwa mu nganda zinyuranye kandi ugira ingaruka nziza cyane cyane mu nganda za peteroli, gaze na peteroli, aho usanga amazi na gaze bibikwa mubushyuhe bwinshi.
Urwego rwo hejuru rwa chromium rutanga kandi ruswa nziza kandi irwanya okiside, ibyo bikaba ari ngombwa mubisabwa gaze. Nyamuneka reba ibisobanuro bya tekinike hepfo ya ASME SA387 Icyiciro cya 11 Icyiciro cya 2.
