I-Hastelloy alloy C22, ekwabizwa ngokuba yi-alloy C22, luhlobo oluthile lwe-austenitic ye-Ni-Cr-Mo Tungsten alloy, enokumelana okunamandla kwi-pitting, i-crevice corrosion kunye noxinzelelo lwe-corrosion cracking.Umxholo ophezulu we-chromium unikezela ukuchasana kwe-oxidation efanelekileyo kwi-medium, ngelixa i-molybdenum kunye ne-tungsten umxholo unokunyamezela okulungileyo kumbindi wokunciphisa.
I-Hastelloy C-22 ine-antioxidant acyl gas, ukufuma, i-fomic kunye ne-acetic acid, i-chloride ye-ferric kunye ne-copper chloride, amanzi olwandle, i-brine kunye nezisombululo ezininzi ezixutywe okanye ezingcolileyo ze-organic and inorganic chemical solutions.
Le ingxubevange ye-nickel inika kwakhona ukuchasana okuphezulu kwiindawo apho iimeko zokunciphisa kunye ne-oxidation zidibana nazo ngexesha lenkqubo.
Le nickel alloy ixhathisa ukubunjwa komda wengqolowa kwindawo echaphazelekayo yokushisa kwi-welding kwaye ngoko ifanelekile kwiinkqubo ezininzi zeekhemikhali phantsi kweemeko ze-welding.
IHastelloy C-22 akufanele isetyenziswe kumaqondo obushushu angaphezu kwe-12509F ngenxa yokwenziwa kwezigaba eziyingozi ezingaphezulu kobu bushushu.

•Ingxubevange yeNickel-Chromium-Molybdenum-Tungsten enoxhathiso olungcono xa kuthelekiswa nayo nayiphi na enye ingxubevange ye-Ni-Cr-Mo, efana neHastelloy C-276,C-4 kunye ne-alloy 625.
•Ukuxhathisa okulungileyo ekufakeni umhlwa, ukubola kweqhekeza kunye noxinzelelo lokuqhekeka kwe-corrosion.
•Ukumelana okugqwesileyo kwi-oxidizing media media kubandakanya iklorini emanzi kunye nemixube equlethe i-nitric acid okanye i-oxidizing acids kunye ne-chlorine ion.
•Ukunikezela ngokuxhathisa okona kulungileyo kokusingqongileyo apho ukuncipha kunye neemeko ze-oxidizing zidibana nazo kwiinkqubo zemisinga.
•Ingasetyenziswa kwindawo ethile yentloko yepropathi yendawo yonke, okanye isetyenziswe kwimveliso eyahlukeneyo yefektri.
•Ukuxhathisa okukhethekileyo kwiindidi ezininzi zeemeko zenkqubo yeekhemikhali kubandakanya i-oxidizers eyomeleleyo efana ne-ferric acid, i-acetic anhydride, kunye nezisombululo zamanzi olwandle kunye ne-brine.
•Uxhathisa ukubunjwa komda wokuziinkozo kwindawo echatshazelwe bubushushu be-weld, ebonelela ngeemeko ezigqwesileyo njenge-welded ukulungiselela izicelo zenkqubo kumashishini asekelwe kwimichiza.
Isetyenziswa kakhulu kwintsimi yeekhemikhali kunye ne-petrochemical, njengesicelo kwizinto eziphilayo eziqulethe i-chloride kunye neenkqubo ze-catalytic. Le nto ifaneleka ngakumbi kubushushu obuphezulu, i-asidi ye-inorganic kunye ne-asidi ye-organic (efana ne-formic acid kunye ne-acetic acid) exutywe nokungcola, ulwandle. i-corrosion environments.Inokusetyenziswa ukwenza ezi zixhobo zilandelayo eziphambili okanye iinxalenye:
