Umbhobho wentsimbi luhlobo lwentsimbi enomngxuma omde cylindrical.Umda wokusetyenziswa kwayo usetyenziswa njengombhobho wokuhambisa ulwelo.Isetyenziswa kakhulu kwimibhobho yokuhanjiswa kwemizi-mveliso efana ne-petroleum, imboni yeekhemikhali, unyango lwezonyango, ukutya, imboni yokukhanya, izixhobo zoomatshini kunye namacandelo okwakhiwa komatshini.Imibhobho yensimbi engenasici yenziwe ngeebhilidi zetsimbi ze-asidi kunye namabakala amelana nobushushu ngokufudumeza, ukubhobhoza, ukulinganisa, ukuqengqeleka okushushu kunye nokusika.Enyanisweni, akukho mveliso inokukhuselwa kwi-corrosion ngaphandle kokuba kwiimeko ezinzulu.Ukuba ipleyiti yethu yensimbi engenasici idliwe, inokuchaphazela ukusetyenziswa kwayo okuqhelekileyo.Ke ngoko, kusafuneka sithathe amanyathelo okuthintela ukuthintela le meko.Ngoku masiqale siqonde izinto ezibangela ukubola kweepleyiti zensimbi ezingenasici?
(1) Ukonakala kwe-Electrochemical:Umkrwelo obangelwa kukudibana phakathi kwepleyiti yensimbi engenasici kunye neenxalenye zentsimbi ye-carbon, kwaye emva koko wenze iseli yegalvanic ene-corrosive medium, eya kuvelisa i-electrochemical corrosion.Ukuba impembelelo ye-pickling passivation ayilungile, ifilimu ye-passivation kumphezulu wepleyiti nayo iya kuba ingalingani okanye incinci kakhulu, ekwalula ukuvelisa i-electrochemical corrosion, i-slag cut, i-splash kunye nezinye izinto ezithintekayo ezifakwe kwipleyiti, kwaye emva koko wenze i-galvanic cell ene-corrosive medium, ekhokelela kwi-electrochemical corrosion.Ukucoca kunye nokucocwa kwe-passivation akucocekanga, okukhokelela kwiimveliso zokubola kweekhemikhali phakathi kwentsalela ye-pickling kunye ne-passivation kunye nepleyiti, kwaye emva koko i-electrochemical corrosion kunye nepleyiti.
(2) Phantsi kweemeko ezithile, ukungcola okuninzi okunamafutha, uthuli, i-asidi, i-alkali, ityuwa, njl.Ukucoca, ukucoca kunye nokugqithisa akucocekanga ngokwaneleyo, okubangela ukugcinwa kolwelo olushiyekileyo, oluphazamisa ngokuthe ngqo ipleyiti.Umphezulu weplate utyhulwa, okukhokelela ekutshatyalalisweni kwefilimu ye-passive, ngoko ke amandla okukhusela iplate ayancitshiswa, kwaye kulula ukusabela ngemidiya yamachiza.
