I-ASTM A269 316/316L Ishubhu ehlanganisiwe yensimbi engagqwali

Ngezinhlelo zokusebenza ezinzima ezivezwe oketshezini olubolayo olunjengamanzi olwandle nezisombululo zamakhemikhali, onjiniyela ngokwesiko baphendukela kuma-valence nickel alloys afana ne-Alloy 625 njengokukhetha okuzenzakalelayo.U-Rodrigo Signorelli uyachaza ukuthi kungani ama-alloys e-nitrogen ephezulu eyindlela eyongayo enokumelana nokugqwala okuthuthukisiwe.

I-Stainless Steel Coiled Tubes Chemical Composition

Ikhwalithi nesitifiketi kunquma ukukhetha kwezinto zezinhlelo ezifana nezishintshisi zokushisa zamapuleti (PHEs), amapayipi namaphampu embonini kawoyela negesi.Ukucaciswa kobuchwepheshe kuqinisekisa ukuthi izimpahla zihlinzeka ngokuqhubeka kwezinqubo esikhathini eside sokuphila kuyilapho kuqinisekiswa ikhwalithi, ukuphepha nokuvikelwa kwemvelo.Yingakho ama-opharetha amaningi ehlanganisa ama-nickel alloys afana ne-Alloy 625 ekucacisweni kwawo namazinga.
Okwamanje, nokho, onjiniyela baphoqeleka ukuthi banciphise izindleko zemali, futhi ama-nickel alloys ayabiza futhi asengozini yokuguquguquka kwentengo.Lokhu kwagqanyiswa ngoMashi 2022 lapho izintengo ze-nickel ziphindeka kabili ngesonto ngenxa yokuhweba ezimakethe, okuba sematheni.Nakuba amanani aphezulu esho ukuthi ama-alloys e-nickel ayabiza ukuwasebenzisa, lokhu kuntengantenga kudala izinselelo zokuphatha konjiniyela abaklami njengoba uguquko lwentengo kungazelelwe lungaba nomthelela enzuzweni kungazelelwe.
Ngenxa yalokho, onjiniyela abaningi bokuklama manje sebezimisele ukushintsha i-Alloy 625 ngezinye izindlela nakuba bazi ukuthi bangathembela kukhwalithi yayo.Okubalulekile ukukhomba ingxubevange efanele ngezinga elifanele lokumelana nokugqwala kwezinhlelo zamanzi olwandle futhi unikeze ingxubevange ehambisana nezakhiwo zemishini.
Into eyodwa efanelekile yi-EN 1.4652, eyaziwa nangokuthi i-Outokumpu's Ultra 654 SMO.Ibhekwa njengensimbi engagqwali ekwazi ukumelana nokugqwala kakhulu emhlabeni.
I-Nickel Alloy 625 iqukethe okungenani i-nickel engu-58%, kuyilapho i-Ultra 654 iqukethe u-22%.Kokubili kunokuqukethwe okufanayo kwe-chromium ne-molybdenum.Ngesikhathi esifanayo, i-Ultra 654 SMO iqukethe nenani elincane le-nitrogen, i-manganese nethusi, i-alloy engu-625 iqukethe i-niobium ne-titanium, futhi intengo yayo iphakeme kakhulu kune-nickel.
Ngesikhathi esifanayo, imele ukuthuthuka okuphawulekayo ngaphezu kwe-316L yensimbi engagqwali, evame ukubhekwa njengesiqalo sokusebenza okuphezulu kwezinsimbi ezingenasici.
Ngokusebenza, i-alloy inokumelana okuhle kakhulu nokugqwala okujwayelekile, ukumelana okuphezulu kakhulu nokugqwala kwemigodi nokugqwala, kanye nokumelana okuhle nokucindezela kokuqhekeka kokugqwala.Kodwa-ke, uma kukhulunywa ngezinhlelo zamanzi olwandle, ingxubevange yensimbi engagqwali inomkhawulo ngaphezu kwe-alloy 625 ngenxa yokumelana kwayo ne-chloride ephakeme.
Amanzi olwandle agqwala kakhulu ngenxa yosawoti wawo wezingxenye ezingu-18,000 kuya kwezingu-30,000 esigidini sama-ion e-chloride.Ama-chloride aveza ingozi yokugqwala kwamakhemikhali emabangeni amaningi ensimbi.Kodwa-ke, izinto eziphilayo emanzini olwandle zingakha futhi ama-biofilms abangela ukusabela kwe-electrochemical futhi athinte ukusebenza.
Ngokuqukethwe kwayo okuphansi kwe-nickel ne-molybdenum, ingxube ye-alloy ye-Ultra 654 SMO iletha ukonga kwezindleko ezibalulekile ngaphezu kwe-alloy ephezulu yendabuko engu-625 kuyilapho igcina izinga elifanayo lokusebenza.Lokhu kuvame ukonga u-30-40% wezindleko.
Ngaphezu kwalokho, ngokunciphisa okuqukethwe kwezakhi ezibalulekile ze-alloying, insimbi engagqwali nayo inciphisa ubungozi bokuguquguquka emakethe ye-nickel.Ngenxa yalokho, abakhiqizi bangaqiniseka ngokwengeziwe ngokunemba kweziphakamiso zabo zokuklama kanye nezingcaphuno.
Izakhiwo zemishini yezinto zokwakha zingenye into ebalulekile konjiniyela.Amapayipi, izishintshisi zokushisa, nezinye izinhlelo kumele zimelane nezingcindezi eziphezulu, amazinga okushisa aguquguqukayo, kanye nokudlidliza komshini noma ukushaqeka.I-Ultra 654 SMO ibekwe kahle kule ndawo.Inamandla aphezulu afana ne-alloy 625 futhi iphakeme kakhulu kunezinye izinsimbi ezingenasici.
Ngasikhathi sinye, abakhiqizi badinga izinto zokwakha nezishiselayo ezihlinzeka ngokukhiqiza ngokushesha futhi zitholakala kalula kufomu lomkhiqizo olifunayo.
Mayelana nalokhu, le ngxubevange iyisinqumo esihle ngoba igcina ukwakheka okuhle nokwelula okuhle kwamamaki endabuko e-austenitic, okuyenza ibe ilungele ukwenza amapuleti okushintshanisa ukushisa aqinile, angasindi.
Futhi inokushisela okuhle futhi itholakala ngezindlela ezihlukahlukene ezihlanganisa amakhoyili namashidi afinyelela ku-1000mm ububanzi no-0.5 kuya ku-3mm noma 4 kuya ku-6mm ubukhulu.
Enye inzuzo yezindleko ukuthi i-alloy ine-density ephansi kune-alloy 625 (8.0 vs. 8.5 kg / dm3).Nakuba lo mehluko ungase ungabonakali ubalulekile, wehlisa amathani ngo-6%, okungakongela imali eningi uma uthenga ngobuningi bemiklamo efana namapayipi esiqu.
Ngalesi sisekelo, ukuminyana okuphansi kusho ukuthi isakhiwo esiqediwe sizoba lula, okwenza kube lula ukwenza izinto, ukuphakamisa nokufaka.Lokhu kuwusizo ikakhulukazi kuzinhlelo zokusebenza ezingaphansi kolwandle kanye nezilwandle lapho amasistimu asindayo okunzima kakhulu ukuphatha.
Uma kucatshangelwa zonke izici nezinzuzo ze-Ultra 654 SMO - ukumelana nokugqwala okuphezulu namandla emishini, ukuqina kwezindleko kanye nokuhlela okunembe - ngokusobala inamandla okuba enye indlela yokuncintisana kakhudlwana kune-nickel alloys.
