Biphase Ibyuma
Ubushyuhe bwo hejuru
◆ F51 (31803) nicyuma gikoreshwa cyane na duplex idafite ibyuma, ikoreshwa cyane cyane mu gutunganya amavuta ya gaz na gaze, mu gutunganya amavuta, gutunganya imiti, ifumbire, peteroli n’indi mirima, mu gukora imashini ihindura ubushyuhe, gukonjesha, n'ibindi. zikunda kwibasirwa no kwangirika kw'ibikoresho by'ingutu. Aho kuba 304L, 316L austenitis ibyuma bidafite ingese.
53 F53 (S32750) nicyuma cyitwa super duplex kitagira umuyonga wongeyeho azote, ikoreshwa cyane mubikoresho bya chimique, peteroli-chimique na marine bisaba imbaraga zidasanzwe no kurwanya ruswa.
◆ F55 (S32760) nicyuma cya super duplex idafite ibyuma bifite imbaraga nyinshi, irwanya cyane chloride ya ruswa yangirika hamwe na ruswa ishobora kwangirika, kandi irashobora gusudira.
◆ 329 (S32900) ifite imbaraga zo kurwanya okiside, kurwanya ruswa, imbaraga nyinshi, kandi irakwiriye kubidukikije nko kurwanya amazi yo mu nyanja.
Steel A4 ibyuma (0Cr17Mn13Mo2N) nicyuma cyibice bibiri, kandi kurwanya ruswa kwayo nibyiza kuruta icyuma gikoreshwa cyane cya austenitike kirimo Mo kirimo 2% -3%. Irashobora gukoreshwa mubifumbire mvaruganda ntoya, ibikoresho bya urea byuzuye, nibindi.
◆ S31050 ifite imbaraga nyinshi zo kurwanya chloride ihungabana, irwanya cyane kwangirika no kwangirika.
◆ U3 ifite anti-scouring na anti-ruswa, kandi ikoreshwa kenshi mugukora ingirabuzimafatizo, intebe za valve nibindi bikoresho byimbere.
◆ HD ikoreshwa cyane mu nganda za elegitoronike, inganda zikoresha amashanyarazi, inganda za peteroli, inganda z’imodoka n’andi mavomero y’amavuta y’amashanyarazi.
◆ C4 ikwiranye nini nini nini ivanze, ivanga, ivanga, ivanga rya horizontal nizindi nganda zimashini.
◆ DS-2 ifite imbaraga zo kurwanya ruswa mu bushyuhe bwo hejuru bwa acide sulfurike, kandi irakwiriye mu nganda z’imashini mu bushyuhe bwo hejuru bwa acide sulfurike.
