Umbhobho wentsimbi we-centrifugally cast ductile cast iron wenziwa kwi-spherical graphite cast iron by centrifugal spinning process.Imibhobho, enokuhambisa imidiya eninzi efana namanzi, ioyile negesi, isetyenziswa ngokubanzi kwiiprojekthi ezahlukeneyo zemibhobho yokwenziwa kwesinyithi, umgodi, ugcino lwamanzi, petroleum. kunye nezinto eziluncedo ezidolophini zoluntu.
I-1.Ukuba namandla aphezulu, ukuqina okulungileyo njengentsimbi kunye nokuxhathisa okungcono kwe-corrosion kunentsimbi, enokubanceda ukuba baxhathise umothuko abahlangabezene nawo ngexesha lokuthutha, ukufakela, ukuphatha kunye nokusetyenziswa.
I-2.I-ductile iron pipe yeyona nto ifanelekileyo yokuthatha indawo yombhobho wentsimbi engwevu kunye nombhobho wentsimbi oqhelekileyo.
3.Imibhobho ye-DI iveliswa ngokuthe tye okuhle, nkqu nobukhulu bodonga, ukuchaneka komgangatho ophezulu, ukugqitywa komphezulu ogudileyo kunye neempawu ezimangalisayo zoomatshini, kunye nokuncamathelisa ngokuqinileyo kwangaphakathi & kwangaphandle umaleko wokugquma.
I-4.I-Flexible Push-in joint kunye ne-rubber gasket isetyenzisiweyo okubangela ukufakwa ngokufanelekileyo kwemibhobho.
5.Zilukhetho oluzinzileyo ngakumbi, njengoko ziqhele ukwenziwa kwizinto eziphinda zisetyenziswe, nto leyo eluphawu olubalaseleyo ngokwembono yendalo esingqongileyo.
I-6.I-diameters yangaphakathi inkulu kuninzi, ukunyuka okunyukayo, okunciphisa ukusetyenziswa kwamandla kunye neendleko zokupompa ngexesha
I-7.Banamandla okuqhuma okuphezulu, okufanelekileyo kwizicelo zoxinzelelo oluphezulu.
