S32750 Ibikoresho
2507 nicyuma cyitwa super duplex kitagira umuyonga gifite imbaraga zo kurwanya ruswa hamwe nimbaraga zirenze 2205. Ihuza ibintu byingirakamaro byibyuma byinshi bya ferritic na austenitis kandi, kubera chromium nyinshi hamwe na molybdenum, bifite imbaraga zo kurwanya ruswa imwe, gutobora no kwangirika.Imiterere y'ibice bibiri iremeza ko ibyuma bifite imbaraga nyinshi zo guhangana na ruswa yangirika hamwe nimbaraga zikomeye za mashini.
Ibirungo byinshi bya chromium na molybdenum bituma irwanya cyane kwangirika kwinshi kwa acide kama nka acide formique, acide acetike, nibindi, kandi ikagira kandi imbaraga zo kwangirika cyane kuri acide organique, cyane cyane irimo chloride.Ugereranije na 904L, yagenewe cyane cyane kurwanya aside irike ya sulfurike, 2507 ifite imbaraga zo kurwanya ruswa irwanya aside sulfurike ivanze ivanze na ion ya chloride.
Urwego 316L ntirushobora gukoreshwa mubidukikije bya hydrochloric, birashobora kwangirika kwangiritse cyangwa kwangirika muri rusange, mugihe 2507 ishobora gukoreshwa mubidukikije bya hydrochloric acide, hamwe nubushobozi bukomeye bwo kurwanya ruswa.Ibiri munsi ya karubone bigera kuri 2507 bigabanya cyane ibyago byo kugwa kwa karbide mungingo zinyuranye mugihe cyo kuvura ubushyuhe, bityo rero, irwanya cyane karbide ifitanye isano na ruswa.
2507 ifite imbaraga zo gukomeretsa cyane, imbaraga zingaruka hamwe na coefficente yo kwagura ubushyuhe buke hamwe nubushyuhe bwo hejuru bwumuriro, ibyo biranga bikwiranye nibice byinshi byubatswe nibice bya mashini.
2507 ntigomba gushyirwa mubushyuhe burenze 300 ℃ igihe kirekire, bishobora kugabanya ubukana bwayo.
Kurwanya ruswa ya S32750 Ibikoresho
1. Kurwanya ruswa
Chromium nyinshi hamwe na molybdenum biri muri SAF 2507 bituma irwanya cyane kwangirika kwinshi kwa acide kama nka acide formique na acide acike.SAF 2507 alloy nayo ifite imbaraga zo kurwanya aside irike, cyane cyane irimo chloride.Kurwanya ruswa.
Ugereranije na 904L, SAF2507 ifite imbaraga zo kurwanya ruswa irwanya aside ya sulfurike ivanze na ion ya chloride.904L ni umusemburo muri austenitis, wagenewe cyane cyane kurwanya aside irike ya sulfurike.
Urwego 316L ntirushobora gukoreshwa mubidukikije bya hydrochloric, birashobora gukorerwa ruswa cyangwa kwangirika muri rusange.SAF2507 irashobora gukoreshwa mugutandukanya aside hydrochloric aside, hamwe nubushobozi bukomeye bwo kurwanya ruswa.
2. Kwangirika hagati
Ibiri munsi ya karubone biri muri SAF 2507 bigabanya cyane ibyago byo kugwa kwa karbide hagati yimvura mugihe cyo kuvura ubushyuhe, kubwibyo, iyi mavuta irwanya cyane karbide ifitanye isano na ruswa.
3. Shimangira ruswa
Imiterere ya duplex ya SAF 2507 ituma irwanya cyane gucika intege.Bitewe nibirimo byinshi bivanze, kurwanya ruswa n'imbaraga za SAF 2507 biruta 2205.
Kumeneka byanze bikunze mubwubatsi, nibindi, bigatuma ibyuma bitagira umwanda byoroha cyane kwangirika mubidukikije bya chloride.SAF 2507 ifite ubushobozi bukomeye bwo kurwanya ruswa.Isocorrosion curve ya SAF 2507 muri acide sulfurike irimo 2000ppm ya chloride ion 0.1 mm / mwaka;isocorrosion curve muri hydrochloric aside 0.1 mm / mwaka.
S32205 Ahantu ho gusaba
2507 ibyuma bidafite ingese bikoreshwa mu nganda za peteroli na gaze;offshore ya peteroli ya Shipotian (imiyoboro ihindura ubushyuhe, uburyo bwo gutunganya amazi na sisitemu yo gutanga amazi, sisitemu yo gukingira umuriro, sisitemu yo gutera amazi, uburyo bwo guhagarika amazi; ibikoresho bya peteroli; ibikoresho bya desalisation (desalination) ibikoresho (nibikoresho biri mumiyoboro yumuvuduko ukabije, imiyoboro yinyanja); n'ibice byubaka bisaba imbaraga nyinshi hamwe no kurwanya ruswa nyinshi; ibikoresho byoza gaze (gutwika).
Imiyoboro yinganda zikora imiti, kontineri, guhanahana ubushyuhe, imiyoboro y’amazi yo mu nyanja mu nganda zangiza, ibikoresho bya peteroli na gaze, sisitemu y’amashanyarazi ya sisitemu yo gukwirakwiza amazi, ibikoresho byo gukaraba, iminara yinjira, ibigega byamazi.
