♦Ipropati yokukhusela umhlwa
Intsimbi etyhidiweyo inepropathi egqibeleleyo yokuchasana nomhlwa, ngokwengxelo, bekukho imibhobho yentsimbi efakwe kwiminyaka engama-300 eyadlulayo isasetyenziswa, kwaye iimeko ezingenakubalwa zibonisa ukuba imibhobho yentsimbi ineminyaka engaphezu kwe-100 yobomi benkonzo.Ngokumalunga nokusetyenziswa kwemibhobho yentsimbi ye-ductile, imbali ingaphezu kweminyaka engama-30.Kodwa i-ductile cast iron iphantse ifane nentsimbi engwevu ekubunjweni kweekhemikhali.Ikwanesilicon, ikhabhoni kunye nezinye izinto kunentsimbi.Ukuxhathisa kwe-ductile cast iron to corrosion nayo ifana ne-grey cast iron.Oku kubonakaliswe ngokusetyenziswa kwaye kungqinwe ngokusemthethweni.
♦Ukukhuselwa kombhobho
Kuyinyani ukuba umbhobho wentsimbi ohamba ngaphantsi komhlaba ogqithisela amanzi okusela nerhasi uya kuphenjelelwa kakhulu yimichiza kunye nepropathi ebonakalayo yomhlaba ngokuthe ngqo.Eyona nto ibalulekileyo ekhokelela ekudlekeni kuxa imibhobho idityanisiwe ukuze ibe liziko lombane elide neliqhubekayo.Ngamanye amazwi, ukuthotywa komhlaba kuya kubonisa iimpawu ezahlukeneyo kwimibhobho eyahlukeneyo.Ngokusekelwe kulo mahluko, yenza i-concentration cell.Inxalenye yeseli enokwenzeka yeseli yoxinaniso iya kuba namandla kakhulu.Ukuba ukubeka iqumrhu lombane emhlabeni kuya kuzisa umgca omde wombane kwaye i-anode yangoku iya kwenza i-boil corrosion.Umbhobho wentsimbi odityanisiweyo ngumzekelo ocacileyo.Umbhobho wentsimbi odityanisiweyo, ongowomatshini wawo okanye uhlobo lwe-T oludityanisiweyo kwaye lutywinwe nge-rubber gasket yokugquma, kukho indawo yokugquma rhoqo ngeemitha ezi-4-6.
♦ Ukumelana nokubola okubangelwa ngumbane wombane
Ekubeni i-iron ductile inokumelana nombane ophezulu, ukuxhathisa ukubola okubangelwa ngumbane wangoku.
