Ubwiza no gutanga ibyemezo bigena guhitamo ibikoresho bya sisitemu nko guhanahana amasahani (PHEs), imiyoboro na pompe mu nganda za peteroli na gaze.Ibisobanuro bya tekiniki byemeza ko umutungo utanga ubudahwema bwibikorwa mugihe kirekire cyubuzima bwiza mugihe ubuziranenge, umutekano no kurengera ibidukikije.Niyo mpamvu abakoresha benshi bashiramo nikel alloys nka Alloy 625 mubisobanuro byabo no mubipimo byabo.
Kugeza ubu ariko, abajenjeri bahatirwa kugabanya igiciro cy’imari, kandi nikel ivanze ihenze kandi ishobora guhindagurika.Ibi byagaragaye muri Werurwe 2022 ubwo ibiciro bya nikel byikubye kabiri mu cyumweru kubera ubucuruzi bw’isoko, bikavugwa.Mugihe ibiciro biri hejuru bivuze ko nikel ivanze ihenze kuyikoresha, iyi ihindagurika itera ibibazo byubuyobozi kubashinzwe ibishushanyo mbonera kuko ihinduka ryibiciro ritunguranye rishobora kugira ingaruka zitunguranye.
Nkigisubizo, abashakashatsi benshi bashushanya ubu bafite ubushake bwo gusimbuza Alloy 625 nubundi buryo nubwo bazi ko bashobora gushingira kumiterere yabyo.Urufunguzo ni ukumenya ibivanze neza hamwe nurwego rukwiye rwo kurwanya ruswa ya sisitemu yinyanja no gutanga umusemburo uhuye nubukanishi.
Ikintu kimwe cyujuje ibyangombwa ni EN 1.4652, kizwi kandi nka Ultra 654 SMO ya Outokumpu.Ifatwa nkibyuma byangirika cyane byangiza ibyuma kwisi.
Nickel Alloy 625 irimo byibura nikel 58%, mugihe Ultra 654 irimo 22%.Byombi bifite hafi ya chromium hamwe na molybdenum.Muri icyo gihe, Ultra 654 SMO nayo irimo azote nkeya, manganese n'umuringa, 625 alloy irimo niobium na titanium, kandi igiciro cyacyo kiri hejuru cyane ya nikel.
Muri icyo gihe, byerekana iterambere ryinshi hejuru ya 316L ibyuma bitagira umwanda, bikunze gufatwa nkintangiriro yo gukora ibyuma bidafite ingese.
Kubijyanye nimikorere, ibinyomoro bifite imbaraga nziza zo kurwanya ruswa muri rusange, kurwanya cyane kwangirika no kwangirika, hamwe no kurwanya neza kwangirika kwangirika.Nyamara, kubijyanye na sisitemu y’amazi yo mu nyanja, ibyuma bidafite ingese bifite akarusho kavanze 625 kubera kurwanya cyane ibidukikije bya chloride.
Amazi yo mu nyanja yangirika cyane kubera umunyu urimo ibice 18,000 - 30.000 kuri miliyoni ya ion ya chloride.Chloride yerekana ingaruka zo kwangirika kumiti yibyuma byinshi.Nyamara, ibinyabuzima byo mu nyanja birashobora kandi gukora ibinyabuzima bitera amashanyarazi kandi bigira ingaruka kumikorere.
Hamwe na nikel nkeya hamwe na molybdenum, Ultra 654 SMO ivanze itanga ikiguzi kinini cyo kuzigama hejuru ya gakondo 625 ivanze mugihe ikomeza urwego rumwe rwimikorere.Ibi mubisanzwe bizigama 30-40% yikiguzi.
Byongeye kandi, mugabanye ibikubiye mubintu byingenzi bivangavanze, ibyuma bidafite ingese nabyo bigabanya ibyago byo guhindagurika kumasoko ya nikel.Nkigisubizo, abayikora barashobora kwigirira icyizere mubyukuri ibyifuzo byabo byashushanyije.
Ibikoresho bya mehaniki yibikoresho nibindi bintu byingenzi kubashakashatsi.Imiyoboro, guhinduranya ubushyuhe, hamwe nubundi buryo bigomba guhangana n’umuvuduko mwinshi, ihindagurika ry’ubushyuhe, kandi akenshi kunyeganyega cyangwa guhungabana.Ultra 654 SMO ihagaze neza muri kano gace.Ifite imbaraga nyinshi zisa na alloy 625 kandi irarenze cyane ugereranije nibindi byuma.
Mugihe kimwe, abayikora bakeneye ibikoresho byoroshye kandi bisudwa bitanga umusaruro byihuse kandi byoroshye kuboneka muburyo bwibicuruzwa byifuzwa.
Ni muri urwo rwego, amavuta ni amahitamo meza kuko agumana imiterere myiza no kuramba neza kumanota gakondo ya austenitis, bigatuma biba byiza mugushushanya amasahani akomeye kandi yoroheje.
Ifite kandi gusudira neza kandi iraboneka muburyo butandukanye harimo ibishishwa n'amabati kugeza kuri 1000mm z'ubugari na 0.5 kugeza 3mm cyangwa 4 kugeza 6mm z'ubugari.
Iyindi nyungu yikiguzi nuko amavuta afite ubucucike buri munsi ya alloy 625 (8.0 na 8.5 kg / dm3).Mugihe iri tandukaniro rishobora gusa nkaho ridafite akamaro, rigabanya tonnage kuri 6%, irashobora kugukiza amafaranga menshi mugihe uguze kubwinshi mumishinga nkimiyoboro ya trunk.
Kuri iyi shingiro, ubucucike buke bivuze ko imiterere yarangiye izaba yoroshye, byoroshye logistique, kuzamura no gushiraho.Ibi ni ingirakamaro cyane cyane mumazi yo mumazi no hanze ya sisitemu aho sisitemu iremereye bigoye kubyitwaramo.
Urebye ibintu byose nibyiza bya Ultra 654 SMO - irwanya ruswa nyinshi nimbaraga za mashini, itajegajega hamwe nubushobozi bwo gutegura neza - biragaragara ko ifite ubushobozi bwo guhinduka muburyo bwo guhatanira ubundi buryo bwa nikel.
