Pfupiso yeDuctile Iron Pipes
Yakagadzirwa nesimbi yakakandwa yakapetwa kaviri (ductile cast iron) inowanzoshandiswa pakufambiswa kwemvura inonwiwa uye kugoverwa kwayo, iyo inogara kwenguva inodarika makore zana. Rudzi urwu rwepombi rwakagadzirwa zvakananga kubva pamapombi esimbi akakandwa kare, ayo akatsiva. Yakanakira kuiswa kwepasi pevhu kwetambo huru dzinofambisa mvura.

Mashandisirwo eDI Pombi
• Munzvimbo yekugovera mvura inonwiwa
• Kutakurwa kwemvura isina kubikwa uye yakachena
• Mvura inoshandiswa mumaindasitiri/mafekitori ekugadzira zvinhu
• Sisitimu yekubata nekurasa tsvina nemadota
• Masisitimu ekudzimisa moto – ari pamhenderekedzo nekunze kwegungwa
• Mumiti yekubvisa munyu
• Nzvimbo huru yemvura yetsvina uye yetsvina
• Sisitimu yekuunganidza nekurasa tsvina yetsvina ine simba regiravhiti
• Mapaipi emvura inoyerera
• Sisitimu yekurasa tsvina inoshandiswa mudzimba nemumaindasitiri
• Sisitimu yekudzokorodza
• Basa rekuisa mapaipi mukati menzvimbo dzekuchenesa mvura netsvina
• Kubatana kwakamira kune matura emagetsi nematangi emvura
• Kuunganidza mirwi yevhu kuti igare yakagadzikana
• Mapombi ekudzivirira pasi penzira huru dzekutakura zvinhu
