Emakethe yamanje yamapayipi ensimbi, ipayipi lensimbi elicwilisiwe elishisayo lithandwa kakhulu phakathi kwabantu ngenxa yohlelo lwalo lokuvikela ukugqwala olungabizi kakhulu, olunganakekeli oluzokwazi ukuhlala amashumi eminyaka ngisho nasezimweni ezinzima kakhulu. Uma sikhuluma ngobuchwepheshe, ungqimba lwezinc lwepayipi elifakwe uthayela elishisayo lumelana nokugqwala kunensimbi engenalutho nensimbi. Kodwa-ke, ngenxa yobuchwepheshe bayo obukhethekile bokucubungula kanye nezindleko eziphezulu zokukhiqiza, ipayipi elifakwe emanzini ashisayo linenani eliphakeme lepayipi lensimbi kunamanye amapayipi avamile emakethe yensimbi.
I-galvanizing imane ihlanganiswe ne-zinc phezu kwemikhiqizo yensimbi. Njengopende, ukunamathela okunothayela kuvikela imikhiqizo yensimbi ekugqwaleni ngokwenza umgoqo phakathi kwesisekelo sensimbi nendawo ezungezile, kodwa ukwenza uthayela kudlulela esinyathelweni esisodwa esikhulu kunopende. Njengomkhiqizi wamapayipi ensimbi ochwepheshile, siphakamisa ukuthi opende basetshenziswe ngendlela efanele ukuze kubuyiselwe ngempumelelo ukuvikeleka kokugqwala okugcwele ezindaweni zokushisela ezimweni ezithile. Ngokuvamile labopende batholakala kumakani okufutha noma ezitsheni ezifanele ukuxutshwa noma ukufaka isifutho.
Ezimweni eziningi, ukulungiswa kwamapayipi ensimbi ashisiwe ashisayo kubandakanya izinhlobo ezivame kakhulu zokulimala noma ukuwohloka kwesistimu yamapayipi, njengokugqwala kwangaphakathi nangaphandle, kanye nezimo lapho umonakalo mkhulu kakhulu. Mayelana namapayipi athile ensimbi abandayo, ukuthintwa kanye nokulungiswa kwezithako zensimbi ezicwilisiwe ezishisayo kubalulekile ukuze kugcinwe umgoqo ofanayo kanye nokuvikelwa kwe-cathodic kanye nokuqinisekisa ukuphila isikhathi eside. Nakuba ukugqoka okufakwe emanzini okushisayo kumelana kakhulu nomonakalo, ama-voids amancane noma amaphutha ekugqokeni kungenzeka ngesikhathi senqubo yokufaka ama-galvanizing noma ngenxa yokuphatha okungalungile kwensimbi ngemva kokugcoba. Ukuthinta kanye nokulungiswa kwezinsimbi kulula kungakhathaliseki ukuthi kusanda kufakwa ama-galvanized noma kusebenza iminyaka. Umkhuba uyafana, kodwa kunemikhawulo eminingi ekulungiseni okuvumelekile komkhiqizo omusha kunalowo okade usebenza. Umkhawulo oyinhloko esimisweni sokukhanda impahla esanda kufakwa uthayela ubukhulu bendawo eshiwo ekucacisweni komkhiqizo. Futhi enye inkambiso yokucaciswa kokuthinta nokulungisa ubukhulu be-coating yendawo yokulungisa.
I-Hot Dip Galvanizing ngokuvamile ifezwa ngezindlela ezimbili, zombili ezicwilisa noma zigcobe insimbi ngokugeza okuwuketshezi kwe-zinc ngemva kwezinqubo ezihlukahlukene. Lesi sici esivikelayo siwukuhlanganisa i-zinc nensimbi, okuzohlala iminyaka eminingi. Kodwa-ke, uma umkhiqizo wakho udinga ukusikwa, ukushiselwa noma ukwenziwa ngenye indlela, kuhlongozwa ukuthi wenziwe kuqala, bese ufakwa uthayela.
