Centrifugally cast ductile iron pombi inogadzirwa kubva ku spherical graphite cast iron by centrifugal spinning process.Mapombi, anogona kufambisa akawanda emvura media semvura, oiri negasi, anoshandiswa zvakanyanya mumhando dzakasiyana dzepombi mapurojekiti esimbi, yangu, kuchengetedza mvura, petroleum. uye utility yevashandi vemumaguta.
1.Kuwana simba rakakwirira, kusimba kwakanaka sesimbi uye zviri nani kupikisa corrosion kupfuura simbi, iyo inogona kuvabatsira kutsungirira kushamiswa kunowanikwa panguva yekufambisa, kuisa, kubata uye kushandiswa.
2.Iyo ductile iron pombi ndiyo yakakodzera inotsiva grey cast iron pipe uye yakajairika simbi pombi.
3.Mapaipi eDI anogadzirwa nekwakanaka kutwasanuka, kunyangwe ukobvu hwemadziro, kurongeka kwepamusoro, kutsetseka kwepamusoro kupedzisa uye zvinoshamisa zvemakanika zvinhu, pamwe nekunamira kwakasimba mukati & nekunze kwekupfeka layer.
4.Flexible Push-in joint uye rubber gasket inoshandiswa zvichiita kuti zvive nyore kuisa mapaipi.
5.Ivo isarudzo yakagadzikana, sezvo ivo vachiwanzo gadzirwa kubva kune zvakadzokororwa zvinhu, inova chinhu chinosimbisa kubva kune yezvakatipoteredza maonero.
6.Inside diameters yakakura kudarika yakawanda, inowedzera kuyerera, iyo inoderedza kushandiswa kwesimba uye kupemha mari nekufamba kwenguva
7.Vane simba rakakwirira rinoputika, iro rakakodzera kushandiswa kwepamusoro.
