Umbhobho wensimbi owenziwe ngesinyithi ngokuqhelekileyo uneendleko ezifanelekileyo kwimarike yombhobho wensimbi yangoku. Xa kuthelekiswa nolunye uhlobo lwemibhobho yokwaleka eqhelekileyo yentsimbi, efana nokupeyintwa okukhethekileyo kunye nomgubo wokugquma, ukugalelwa kwentsimbi kufuna umsebenzi omninzi, nto leyo ekhokelela kwiindleko zokuqala eziphezulu kwiikontraka. Ngaphandle koko, ngenxa yokuqina kwayo kunye neempawu ezichasene ne-corrosive, umbhobho wensimbi owenziwe ngesinyithi unokuphinda usetyenziswe kwaye usetyenziswe kwakhona, apho kwinqanaba elithile ligcina imali eninzi ngexesha lomsebenzi wokugcinwa kweposi.
Namhlanje, umbhobho oshushu oditshiweyo wegalvanized uthathwa njengethandwa kakhulu phakathi kwabasebenzisi abaninzi namhlanje. Enye into, inkqubo ye-galvanization ikhusela intsimbi kumonakalo wokugqwala onokuthi kwenzeke ngexesha lokuthutha, ukufakwa kunye nenkonzo. Uluhlu lwe-zinc ebusweni bombhobho lunokwenza umqobo wokukhuselwa kweemveliso zetsimbi ukwandisa ubomi benkonzo kwizicelo. Ngakolunye uhlangothi, olu luhlu luphinde luxhathise ukugqoka kunye nemikrwelo, eyenza ukuba intsimbi ibonakale ikhangeleke ngakumbi. Ngoluhlu lokukhusela, imibhobho ingasetyenziselwa kwiindawo zangaphandle, kwaye inokumelana nokulimala kwezinye iimpembelelo zokusingqongileyo. Lo mbhobho okhethekileyo wentsimbi usetyenziswa kwizicelo ezininzi zangaphandle ezifana nocingo, izithuba zocingo kunye nemibhobho yokubonelela ngamanzi.
Uvavanyo kunye nophononongo lubonise ukuba umndilili wobomi bentsimbi esetyenziswe njengesixhobo solwakhiwo ungaphaya kweminyaka engama-50 kwindawo yasemaphandleni kunye neminyaka engama-20 ukuya kwengama-25 nangaphezulu kwindawo egqithisileyo yasedolophini okanye eselunxwemeni. Ngaloo nto, iikontraka zinokusebenzisa ngokuzithemba olu hlobo lombhobho wensimbi yesakhiwo kwiprojekthi. Ngokobuchwephesha, i-galvanization eshushu editshiweyo inesimo esiphindwe kabini sokhuselo lwemali esetyenziswayo. Njengesithintelo sokugquma, inika i-zinc eqinile, i-metallurgically bounded coating ye-zinc egubungela ngokupheleleyo umphezulu wentsimbi kwaye itywine intsimbi ukusuka kwisenzo sokutshabalalisa kokusingqongileyo. Ngaphandle koko, ukuziphatha kwedini le-zinc kukhusela intsimbi, nalapho umonakalo okanye ukupheliswa okuncinci kwi-coating kwenzeka. Iingubo ezenziwe ngegalvanized zibonakalise ukusebenza phantsi kweemeko ezininzi zokusingqongileyo. Ukuxhatshazwa kwe-corrosion of coatings ye-zinc kunqunywe ngokuyinhloko ngobunzima bengubo kodwa iyahluka ngobunzima beemeko zokusingqongileyo.
Ngokungafaniyo nezinye izixhobo zentsimbi, umbhobho oshushu oditshiweyo wentsimbi ulungele ukusetyenziswa xa uhanjiswa. Akukho kulungiswa okongeziweyo komphezulu ofunekayo, akukho kuhlolwa kwexesha elide, ukupeyinta okongezelelweyo okanye iingubo ezifunekayo. Emva kokuba isakhiwo sihlanganiswe, iikontraka zinokuqalisa ngokukhawuleza inqanaba elilandelayo lokwakha ngaphandle kokukhathazeka malunga nezixhobo zentsimbi. Ukuba ukhetha umbhobho oshushu oditshiweyo wentsimbi kwisicelo sakho, unokuphepha iindleko zokugcina kunye nokutshintsha imibhobho edlekileyo eya kukugcina imali eninzi kwiprojekthi. Njengomvelisi wemibhobho yentsimbi yobuchwephesha e-China, iQela le-DongPengBoDa Steel Pipe lizibophelele ekukunikezeni iintlobo ezahlukeneyo zemibhobho yentsimbi kwiprojekthi yakho elandelayo. Wamkelekile ukuba uQhagamshelwe nathi nangaliphi na ixesha xa ukulungele.
