HASTELLOYC4iyingxubevange eyakhiwe nge-Nickel, i-chromium, ne-molybdenum. Ithathwa kakhulu njengengxube esebenza ngezindlela eziningi yokulwa nokugqwala. Le ingxubevange ibonisa ukumelana ukwakheka umngcele okusanhlamvu precipitates lapho ngaphansi ukushisa Welding, okwenza kube ifaneleka ezihlukahlukene inqubo amakhemikhali izicelo esimweni ashiselwe. Ngaphezu kwalokho, i-alloyC4ikhombisa ukumelana okuvelele kokugoba, ukuqhekeka kwe-stress-corrosion, kanye ne-oxidizing atmosphere efika ku-1900°F. Inokumelana okukhethekile nezinhlobonhlobo zezindawo zamakhemikhali.
IZICELO:
1.Imboni yamaphepha: Izitshalo zokugaya kanye ne-bleach.
2.Izindawo zegesi emuncu: Izingxenye ezivezwe kugesi omuncu.
3.Izitshalo zokususa i-flue-gas desulfurization: Izinto ezisetshenziswa ezitshalweni zokususa i-flue-gas desulfurization.
I-4.Izindawo ze-Sulfuric acid: Ama-evaporator, izishintshi zokushisa, izihlungi, nezixube ezisetshenziswa ezindaweni ze-sulfuric acid.
I-5.I-Sulfuric acid reactors: Izisetshenziswa ezisetshenziswa kuma-sulfuric acid reactors.
6.Inqubo ye-Organic chloride: Impahla esetshenziswa kunqubo ye-organic chloride.
7.Izinqubo ze-Halide noma ze-acid catalyst: Imishini esetshenziswa ezinqubweni ezisebenzisa i-halide noma i-acid catalysts.
