Ukubukelwa kwamapayipi

Imishini yokucubungula eshisayo ezinhlathini zezimboni, ezinjengamabhasikidi, amathreyi, nokulungiswa. Ngokucutshungulwa kwamakhemikhali noma kwe-petrochemical kusetshenziselwa ukushintshaniswa kokushisa nezinhlelo zamapayipi kuma-nitric acid media, ikakhulukazi lapho ukumelana nokuqhekeka kwe-chloride ukuxabana kokuqhekeka.

Incoloy 800 \ 800h \ 800ht iyikhambi eliqinile lesixazululo se-nickel chromium iroy alloys nge-aluminium ne-titanium ukuthuthukisa ukubhujiswa kanye nokuphikiswa oxidation.

Zisetshenziselwa insiza yokushisa ephezulu, lapho kudingeka khona i-oxidation kanye ne-carburburation. Ngezakhiwo ezinhle kakhulu zokucindezela kwengcindezi, noma insiza yomkhumbi yengcindezi engenhla kwe-815¡Ãc, incoloy 800h noma incoloy 800ht kufanele isetshenziswe.

I-alloy iyakwazi ukuhlala ezinzile futhi igcine isakhiwo sayo se-auntenitic. I-Incoloy 800 isetshenziswa ngokuyinhloko kuzinhlelo zokusebenza ezinamazinga okushisa aze afike ku-1100¡Ã f, lapho ama-alloys 800h kanye ne-800ht asetshenziswa ngokujwayelekile emazingeni okushisa angenhla kwe-1100¡.

Isetshenziselwa izakhi ezidinga ukuvezwa kwamanzi olwandle kanye nengcindezi ephezulu yemishini.

Impendulo evilaphayo yobudala ye-Alloy 718 izimvume zokuvuselela kanye nokufudumala ngaphandle kokuqina okuzenzakalelayo ngesikhathi sokushisa nokupholisa.

I-Incons 718 isibe wusizo ezinhlobonhlobo zezicelo ezisukela ekusebenzeni kokukhiqiza emishini yezempi kanye nemboni ye-aerospace.

Le alloy le-nickel isetshenziswa kusuka emazingeni okushisa ama-cryogenic kuze kufike ku-1200¡Ã f.

Enye yezinto ezehlukanisa ukwahlukanisa kwe-Incon 718¡¯s ukwakheka kwe-niobium ukuvumela ubusuku obuvumayo obuvumela ukuhlanganisa nokushiswa ngaphandle kokuqina kokushisa nokupholisa.

Ezinye izindawo ezithandwayo ze-nickel-chromium ziseminyakeni evulwe ngokwanele ngokungezwa kwe-aluminium ne-titanium.

Le alloy lensimbi ye-nickel isetshenziswe kalula futhi ingahle ifakwe kunoma yisiphi isimo se-annealed noma semvula (yobudala).

Le superloy isetshenziswa ezimbonini ezahlukahlukene ezinjenge-aerospace, ukucubungula amakhemikhali, ubunjiniyela basolwandle, imishini yokulawula ukungcoliswa, kanye nokuphendula kwenukliya.

I-alloy yenziwa ngo-50-55% nickel + cobalt (nge-cobalt linqunyelwe ku-1% max) kanye ne-17-2% chromium.

I-Hastelloy C276 iyi-nickel-chromium-molybdenum eyenziwe ye-alloy ebhekwa njenge-alloy ehlukahlukene kakhulu etholakalayo.

Le alloy iyamelana nokwakhiwa kwemingcele yokusanhlamvu ethambekele endaweni ephazamiseka ukushisa, ngaleyo ndlela okwenza kube lulungele izinhlelo eziningi zenqubo yamakhemikhali esimweni se-welded.

I-Alloy C-276 futhi inokumelana kahle nokuphamba, ukuqhekeka kokugqwala kokugqwayiza kanye no-oxidizing atmosperes aze afike ku-1900¡ãf. I-Alloy C-276 inokumelana okuhlukile ezindaweni ezahlukahlukene zamakhemikhali.

Ukuphikiswa okuvelele okuvelele futhi okuguquguqukayo kwe-inconel 625 alloy ngaphansi kwamazinga okushisa kanye nezingcindezi kuyisizathu esiyinhloko sokwamukelwa kwayo okubanzi kwensimu yamakhemikhali.

I-Hastelloy C276 ingenye yama-alloys ambalwa amelana ne-wet chloride gesi, i-hypochlori ne-chlorine dioxide solutions.

I-625 inokumelana okuvelele ekuphathweni okukhohlisayo, ukugqwala kwe-crevice kanye nokugqwala kokuxhumana.

I-Hastelloy C276 inokumelana okuhlukile kwizisombululo eziqinile ze-oxidizing usawoti, njengama-forric nama-chupric cuprides.

I-625 icishe ibe yinkululeko ephelele evela ku-chloride incipha ukuqhekeka kokugqwala kwengcindezelo.

I-Hastelloy C276 ayithambekele ekutholeni imingcele yokusanhlamvu kunesimo se-welded futhi ngakho-ke ilungele izinhlelo eziningi zamakhemikhali.

Inokumelana okuphezulu ku-oxidation emazingeni okushisa aphakeme afinyelela ku-1050c.

I-Incoloy Alloy 800 isetshenziswa kabanzi kumishini okufanele ibe namandla aphezulu kanye nokumelana ne-oxidation, i-carburation neminye imiphumela elimazayo yokuvezwa kokushisa okuphezulu.

Lapho esesimweni esilukhuni seminyaka yobudala, i-monel K-500 inokuthambekela okukhulu kokuqhekeka kwengcindezi ezindaweni ezithile kune-monel 400

Amandla ale ncwadi yensimbi ye-nickel igcinwa ku-1200¡Ã fy kodwa ihlala i-ructile futhi igxile emazingeni okushisa ka-400¡Ã f. Ibanga layo elincibilikayo lingu-2400-460¡Ã f.

I-Alloy K500 yacwengiswa ngu-Electro Slag Refining (ESR), ukuqinisekisa ukuthi ikhwalithi ehlanzekile futhi ephezulu kakhulu yezinto ezibonakalayo iyahlinzekwa.

I-Hastelloy B-2 i-nickel-base yenza i-alloy enomqondo omuhle kakhulu we-hydrochloric acid kuwo wonke amazinga okuhlala kanye namazinga okushisa.

Inokumelana okukhulu ekuqhekekeni kwengcindezi - ukuqhekeka kokugqwala nokukhonkotha. Hastelloy B-2? Futhi ifaka ukumelana ne-hydrochloric acid kuwo wonke amazinga okuhlala kanye namazinga okushisa.

Ingasetshenziswa ekunciphiseni izindawo zamakhemikhali kanye nemboni yokucubungula amakhemikhali.
