IMALI yemveliso
I-1.Ukumelana nokugqwesa kwe-corrosion kwimidiya eyahlukeneyo ye-corrosion kwi-oxidizing kunye nokunciphisa imimandla.
I-2.Ukuchasana okugqwesileyo kwi-pitting corrosion kunye ne-crevice corrosion kwaye akukho xinzelelo lwe-corrosion cracking ebangelwa yi-chlorides.
3.Ukuchasana ngokugqwesileyo kwi-corrosion ye-inorganic acids efana ne-nitric acid, i-phosphoric acid, i-sulfuric acid, i-hydrochloric acid, kunye nomxube we-sulfuric acid kunye ne-hydrochloric acid, njl.
I-4.Ukuchasana ngokugqwesileyo kwi-corrosion yeentlobo ze-acids ze-inorganic inorganic solutions.5.
I-5.Iqondo lokushisa ukuya kwi-40 ℃, kwiindidi ezahlukeneyo zesisombululo se-hydrochloric acid sinokubonisa ukuxhathisa okulungileyo kokuhlwa.
6.Good ukusebenza kunye weldability ngaphandle post-weld cracking susceptibility.
7.Wall ubushushu kwi -196 ~ 450 ℃ isiqinisekiso sokuvelisa inqanawa yoxinzelelo.
8. NgoMbutho waseMelika weeNjineli ze-Corrosion I-NACE isatifikethi esisemgangathweni (MR-01-75) ngokuhambelana nemigangatho ephezulu yokusetyenziswa kwi-sour gas environment grade VII.
Isicelo semveliso
I-Soft annealed low carbon alloy 625 isetyenziswa ngokubanzi kushishino lwenkqubo yeekhemikhali, apho ukuxhathisa kwayo kakuhle kokubola kunye namandla aphezulu kwenza ukuba isetyenziswe njengecandelo elincinci lesakhiwo. I-625 alloy ingasetyenziswa xa idibana namanzi olwandle kwaye iphantsi koxinzelelo oluphezulu lomatshini.
Iindawo ezisetyenziswayo eziqhelekileyo: 1.
1. Amacandelo eenkqubo zemichiza ephilayo equkethe ikloridi, ngakumbi apho kusetyenziswa i-acidic chloride catalysts.
2. Iidigester kunye neetanki zeblitshi zepulp kunye neshishini lephepha.
3. Iitora zokufunxa, izifudumezi, ii-flue gas inlet baffles, iifeni (ezimanzi), ii-agitators, iziphambukisi kunye nemibhobho kwiisistim ze-flue gas desulphurization.
4. Izixhobo kunye namacandelo okwenziwa kwezicelo kwiindawo zegesi ye-asidi.
5. I-Acetic acid kunye ne-ethyl alcohol reaction generators. 6. Iicondensers ze-Sulfuric acid.
