Mu ci ryinshi, uruganda ruhuze gukora imirimo itandukanye ya valve. Mu minsi mike ishize, uruganda rwa Jinbin rwarangije irindi tegeko ryaturutse muri Iraki. Iki cyiciro cy'irembo ry'amazi ni ibyuma 304 bidafite ingeseintoki, iherekejwe na 304 ibyuma bidafite ingese hamwe na gari ya moshi ya metero 3.6. Kuzenguruka uruti rwa valve bisukurwa na aside ultrasonic kugirango ikureho ikizinga.

Gukoresha ibikoresho 304 bidafite ibyuma byo gukorapenstockifite ibyiza bikurikira:

304 ibyuma bitagira umwanda birimo igice kinini cya chromium na nikel, bishobora kurwanya isuri yibitangazamakuru bitandukanye bya chimique, nka acide, alkalis, nu munyu. Irakwiriye cyane cyane kubidukikije bishobora guhura n’imyanda n’amazi yo mu nyanja, kandi birashobora gukomeza imiterere n’imiterere y’imashini ahantu h’ubushyuhe bwo hejuru, bigatuma bikwiranye n’ubushyuhe bwo hejuru.

304 ibyuma bidafite ingese biroroshye gutunganya no kubishushanya, bikwiranye no gukora amarembo atandukanye afite imiterere, kandi byoroshye kuzuza ibisabwa byubushakashatsi. Ibi bikoresho bifite imyambarire myiza yo kwambara, irashobora kurwanya kwambara no gushushanya, kugumana ubuso bwiza nuburanga bwiza, kandi ifite imbaraga nubukomezi mubushyuhe bwicyumba, bigatuma ubwizerwe numutekano by irembo mubikorwa bitandukanye byubwubatsi.

Ubuso bwibyuma 304 bidafite ingese biroroshye kandi birasa, hamwe nibyiza byiza byo gushushanya nibyiza, bikwiranye nibisabwa hamwe nibisabwa cyane kugirango ugaragare. Irashobora gukora firime yuzuye ya oxyde hejuru yikirere, ikarinda neza okiside nicyuma, kandi ikongerera igihe cyumurimo. Ntabwo ikubiyemo ibyuma biremereye byangiza umubiri wumuntu, byujuje ubuziranenge bwumutekano n’umutekano, birakwiriye gutunganya ibiribwa, ibikoresho byubuvuzi nizindi nzego, ni ibikoresho bisubirwamo, bitangiza ibidukikije, kandi bihuye nigitekerezo cyiterambere rirambye. Bitewe no kwangirika kwangirika no kwambara ibyuma 304 bidafite ingese, amafaranga yo gufata neza irembo ni make.

Izi nyungu zituma ibyuma 304 bidafite ingese bihitamo gukora nezainkuta, cyane cyane mubwubatsi bwa hydraulic, gutunganya imyanda, hamwe n’ibidukikije byo mu nyanja, bigatuma ibikorwa byigihe kirekire bihoraho hamwe nibisabwa bike byo kubungabunga amarembo. Niba ufiteirembovalve ibikoresho bisabwa, nyamuneka twandikire hepfo hanyuma uzabona igisubizo mumasaha 24.
