I-alloy 20 Ibha Yensimbi Engagqwali

I-UNS N08020

I-UNS N08020, eyaziwa nangokuthi i-Alloy 20 ingenye yensimbi engagqwali “enhle kakhulu” eyenzelwe ukumelana nokuhlasela kwe-asidi, ngenxa yalokhu, kukhona ukusetshenziswa kwayo okuhlukahlukene kuzo zombili izimboni ezingenasici neze-nickel. I-alloy 20 ibonakala ingena phakathi kokubili izigaba ze-stainless ne-nickel, njengoba iqukethe izici zakho zombili; kodwa-ke, isistimu yezinombolo ezihlanganisiwe (i-UNS) ekugcineni iyayibona njengengxube ye-nickel esekelwe, yingakho inombolo ye-UNS N08020.

I-alloy 20 iyingxubevange esekwe nickel-iron-chromium enezengezo zethusi ne-molybdenum. Okuqukethwe kwayo kwe-nickel kusiza ekucindezelekeni kwe-ion ye-chloride kanye nokumelana nokugqwala. Ukwengezwa kwethusi ne-molybdenum kunikeza ukumelana nezindawo ezinobutha, ukugqwala kwemigodi kanye nokugqwala kwemifantu. I-Chromium yengeza ekuphikisweni kwayo kwezindawo ezine-oxidizing, njenge-nitric acid, futhi i-columbium (noma i-niobium) inciphisa imiphumela yemvula ye-carbide. Izindlela eziningi zokushisela zingasetshenziswa uma usebenza ne-Alloy 20, ngaphandle kwe-oxyacetylene welding. Kungase futhi kushise kwakhiwe kusetshenziswa amandla afanayo adingekayo ekusebenzeni okushisayo kwezinsimbi ezingenasici ze-austenitic. Mayelana nokusebenza komshini, ukuqedwa okuvelele kungenzeka kusetshenziswa isivinini sokusetha esifanayo nesenqubo esisetshenziselwa izinsimbi ezingenasici ze-austenitic, njenge-Stainless Steels 316 noma 317.

Izimboni ezisebenzisa i-Alloy 20 zifaka:

• Amakhemikhali
• I-flue gas desulfurization
• Ukucubungula ukudla
• Ukuphathwa koketshezi lwezimboni
• Ukuhlanza insimbi
• Ukuxuba
• Uwoyela
• Ezemithi
• Ukukha
• Ipulasitiki
• Iprosesa yamapayipi
• Izincibilikisi
• I-synthetic fiber
• Irabha yokwenziwa

Imikhiqizo eyakhiwe ingxenye noma ngokuphelele ye-Alloy 20 ihlanganisa:

• Amaphampu we-Centrifugal
• Ama-valve okulawula
• Ama-valve ebhola e-Cryogenic
• Ukushintshwa kwezinga lokuntanta
• Amaswishi agelezayo
• Ama-valve okunciphisa ingcindezi
• Amaphampu enqubo yegiya elijikelezayo
• Ama-gaskets amanxeba okuvunguza
• Izihlunu
