Isici somkhiqizo
I-1.Ukumelana nokugqwala okuhle kakhulu emithonjeni ehlukahlukene egqwalayo endaweni ye-oxidizing nokunciphisa.
I-2.Ukumelana okuhle kakhulu nokugqwala kwe-pitting kanye nokugqwala kwe-crevice futhi akukho ukuqhekeka kokugqwala kwengcindezi okubangelwa ama-chlorides.
3.Ukumelana okuhle kakhulu nokugqwala kwama-acids angaphili njenge-nitric acid, i-phosphoric acid, i-sulfuric acid, i-hydrochloric acid, nengxube ye-sulfuric acid ne-hydrochloric acid, njll.
4.Ukumelana okuhle kakhulu nokugqwala kwezinhlobonhlobo zama-asidi angaphili ezixazululweni ezixubile.5.
I-5.Izinga lokushisa elifika ku-40 ℃, ekugxilweni okuhlukahlukene kwesisombululo se-hydrochloric acid kungabonisa ukumelana nokugqwala okuhle.
6.Ukusebenza okuhle nokushisela ngaphandle kokungenwa kokuqhekeka kwe-post-weld.
7.Wall lokushisa -196 ~ 450 ℃ ingcindezi umkhumbi ukukhiqiza isitifiketi.
8. Nge-American Association of Corrosion Engineers Isitifiketi esijwayelekile se-NACE (MR-01-75) esihambisana namazinga aphezulu okusetshenziswa endaweni yegesi emuncu ebangeni le-VII.
Isicelo somkhiqizo
I-Soft annealed low carbon alloy 625 isetshenziswa kabanzi embonini yezinqubo zamakhemikhali, lapho ukumelana nokugqwala kwayo okuhle namandla aphezulu kuyenza ikwazi ukusetshenziswa njengengxenye yesakhiwo esincanyana. I-625 alloy ingasetshenziswa lapho ihlangana namanzi olwandle futhi ingaphansi kwengcindezi ephezulu yokusebenza.
Izindawo ezijwayelekile zokufaka isicelo: 1.
1. Izingxenye zezinqubo zamakhemikhali eziphilayo eziqukethe ama-chloride, ikakhulukazi lapho kusetshenziswa khona ama-catalysts e-acidic chloride.
2. Ama-digesters namathangi e-bleach embonini ye-pulp nephepha.
3. Imibhoshongo yokumuncwa, izifudumezi kabusha, ama-flue gas inlet baffles, amafeni (amanzi), ama-Agitator, iziphambukisi kanye namaflue gas desulphurization systems.
4. Izinsiza kanye nezingxenye zokukhiqiza izinhlelo zokusebenza ezindaweni zegesi ene-asidi.
5. I-acetic acid kanye ne-ethyl alcohol reaction generators. 6. I-sulfuric acid condensers.
