Ipayipi lensimbi engagqwali liwuhlobo lwensimbi ende eyisilinda engenalutho.Ububanzi bayo bokusebenza busetshenziswa njengepayipi lokudlulisa uketshezi.Isetshenziswa kakhulu kumapayipi okudluliselwa kwezimboni afana ne-petroleum, imboni yamakhemikhali, ukwelashwa, ukudla, imboni yokukhanya, izinsimbi zomshini kanye nezingxenye zesakhiwo semishini.Amapayipi ensimbi engagqwali enziwe ngamabhilidi ensimbi ane-asidi namazinga amelana nokushisa ngokushisisa, ukubhobozwa, ukulinganisa, ukuginqika okushisayo nokusika.Eqinisweni, awukho umkhiqizo ongavikelwa ekugqwaleni ngaphandle uma kwenzeka kwezinye izimo ezimbi kakhulu.Uma ipuleti lethu lensimbi engagqwali ligqwalile, kungase kuthinte ukusetshenziswa kwalo okuvamile.Ngakho-ke, sisadinga ukuthatha izinyathelo zokuvikela ukugwema lesi simo.Manje ake siqale siqonde izici ezibangela ukugqwala kwamapuleti ensimbi engagqwali?
(1) Ukugqwala kwe-Electrochemical:Ukuklwebheka okubangelwa ukuthintana phakathi kwepuleti lensimbi engagqwali nezingxenye zensimbi ye-carbon, bese kwakheka iseli le-galvanic eline-corrosion medium, elizokhiqiza ukugqwala kwe-electrochemical.Uma umphumela we-pickling passivation ungemuhle, ifilimu ye-passivation ebusweni bepuleti nayo izoba ingalingani noma ibe mncane kakhulu, okubuye kube lula ukukhiqiza ukugqwala kwe-electrochemical, ukusika kwe-slag, i-splash nezinye izinto ezivame ukugqwala ezinamathele epuleti, futhi bese yakha ingqamuzana le-galvanic nge-corrosion medium, okuholela ekugqwaleni kwe-electrochemical.Ukuhlanzwa kwe-pickling kanye ne-passivation akuhlanzekile, okuholela emikhiqizweni yokugqwala kwamakhemikhali phakathi kwezinsalela ezisele zokukhetha kanye ne-passivation kanye nepuleti, bese kuba ukugqwala kwe-electrochemical nepuleti.
(2) Ngaphansi kwezimo ezithile, ukungcola okuningi okunamafutha, uthuli, i-asidi, i-alkali, usawoti, njll. okunanyathiselwe ebusweni bezingcwecwe zensimbi engagqwali kuzoguqulwa kube imidiya egqwalayo, ezosabela ngamakhemikhali nezinye izingxenye zamapuleti, kubangele ukugqwala kwamakhemikhali nokugqwala.Ukuhlanza, ukucosha kanye nokwedlula akuhlanzeki ngokwanele, okuholela ekugcinweni koketshezi olusele, olugqwalisa ipuleti ngokuqondile.Ubuso bepuleti bukhishwa, okuholela ekubhujisweni kwefilimu ye-passive, ngakho-ke ikhono lokuvikela lepuleti liyancipha, futhi kulula ukusabela ngemidiya yamakhemikhali.
