Nzira yekurwisa-corrosion kurapwa kweductile iron pipe:
1. Pombi yeasphalt coating kutakura gasi.Preheating pombi isati yapenda inogona kuvandudza kunamatira kwe asphalt pendi uye nekukurumidza kuoma.2. Cement mortar lining + Iyi yemukati anti-corrosion chiyero inokodzera mapaipi epaipi, iyo inogona kuvandudza kushorwa kweiyo lining.3. Epoxy coal tar tar coating haisi yakakodzera chete kune mapaipi egasi, asiwo kune mapaipi emvura.Icho chifukidziro chezvikamu zviviri nekukwirira kwepamusoro uye kutaridzika kwakanaka 4. Epoxy ceramic lining inokodzera mapaipi emvura uye gasi mapaipi, asi nekuda kwekuoma kwekugadzira uye kudhura kwakanyanya, ine zvimwe zvisingakwanisi mukushandiswa.Iyo epoxy ceramic lining ine yakakwirira adhesion uye yakakwirira kupedzisa, uye yakanakisa anti-corrosion coating.5. Aluminate simenti pendi kana sulfate simenti pendi inokodzera mukati anticorrosion ye ductile iron mapaipi emapombi emvura yetsvina, iyo inovandudza kushorwa kweasidhi uye alkali zvikamu mutsvina.6. Polyurethane coating ine simba rakanaka kwazvo mu-anti-corrosion effect.
