Ductile iron pipe imhando yepombi yesimbi yakakandwa.Hunhu hunodiwa hwekukanda simbi pombi spheroidization giredhi kutonga kwe1-3 (spheroidization rate "80%), saka michina yemidziyo pachayo yakagadziridzwa zvirinani, nehunhu hwesimbi, kuita kwesimbi.Annealed ductile iron pombi, iyo metallographic chimiro ndeye ferrite uye ishoma pearlite, yakanaka michina zvivakwa, yakanakisa corrosion resistance, yakanaka ductility, yakanaka yekuisa chisimbiso mhedzisiro, nyore kuisa, inonyanya kushandiswa kumanisiparati, maindasitiri nemabhizinesi emigodhi mvura, gasi, mafuta uye zvichingodaro.
Imwe huwandu hwe spherical graphite inogoverwa pane ferrite uye pearlite matrix.Zvinoenderana nezvinodiwa zvezita dhayamita uye elongation, chikamu cheferrite uye pearlite mumatrix chakasiyana.Chiyero chepearlite mudiki dhayamita kazhinji hachipfuure makumi maviri muzana, uye icho mudhayamita hombe chinowanzodzorwa chingangoita 25%.
Iyo ine hunhu hwesimbi, kuita kwesimbi, yakanakisa anticorrosion performance, yakanaka ductility, yakanaka yekuisa chisimbiso mhedzisiro, nyore kuisa, inonyanya kushandiswa kune emanisipala, maindasitiri nemabhizinesi emigodhi kugovera mvura, gasi, mafuta uye zvichingodaro.Ndiyo yekutanga sarudzo yepombi yekupa mvura, ine mutengo wakanyanya kuita.Kuenzaniswa ne PE pombi, kubva panguva yekuisa, kuiswa kwe spherical inki pombi iri nyore uye nekukurumidza kupfuura PE pombi, uye mukati nekunze kudzvanywa kuri nani mushure mekuiswa;Kubva pane airtight uye anticorrosive maonero, mushure mekugadzwa kwe spherical inki chubhu airtight zviri nani, asiwo kuburikidza nemhando dzakasiyana-siyana dzeanticorrosive nzira dzekuvandudza kurwisana kwekuora;Mukutaura kwekushanda kwe hydraulic, zvinyorwa zve spheroidal inki tube zvinowanzoreva dhayamita yemukati, uye zvinyorwa zve PE chubhu zvinowanzoreva dhayamita yekunze, nokuti pasi pezvinyorwa zvakafanana, spheroidal inki tube inogona kubudirira kukuru kumhanya;Kubva pane yakazara yekumisikidza uye kugadzirisa mutengo wekutarisa, spheroidal inki chubhu ine yakanyanya kunaka mutengo kuita.Inner wall spraying zinc, simende mortar anti-corrosion materials.
