♦ The corrosion protection property
Simbi yakakandwa ine midziyo yekudzivirira ngura yakakwana, maererano nerekodhi, pakanga paine mapaipi esimbi akaiswa makore anopfuura 300 apfuura achiri kushandiswa, uye zviitiko zvisingaverengeki zvinoratidza kuti pombi dzesimbi dzakakandwa dzine makore anopfuura zana ehupenyu hwebasa.Panyaya yekushandiswa kwepombi dzesimbi, nhoroondo inodarika makore makumi matatu.Asi ductile cast iron inenge yakafanana negrey cast iron mumakemikari.Iyo ine zvakare yakawanda kwazvo silicon, kabhoni uye zvimwe zvinhu kupfuura simbi.Kupokana kwe ductile cast iron kusvika pakuora kwakafananawo neiyo yegrey cast iron.Izvi zvakaratidzwa mukushandiswa uye zvakaratidzwa empirically.
♦Kudzivirirwa kwekuora kwepombi
Ichokwadi kuti pasi pevhu ductile iron pombi inoendesa mvura inonwiwa uye gasi inozokanganiswa zvakanyanya nekemikari uye pfuma yevhu zvakananga.Chinhu chinonyanya kukosha chinoguma nekuora ndechekuti pombi dzinobatanidzwa kuti dzive refu uye dzinoramba dzichiisa magetsi.Mune mamwe mazwi, kukora kwevhu kucharatidza maitiro akasiyana pamapaipi akasiyana.Kubva pamusiyano uyu, inoumba concentration cell.Partial cell mukana weconcentration cell ichave yakasimba kwazvo.Kana ukaisa electrify entity muvhu zvinounza mutsara wakareba wemagetsi emazuva ano uye zvino anode inoumba yakanyanya kuboil corrosion.Iyo welded simbi pombi muenzaniso wakajeka.Ductile iron pombi, ine mechanichani kana T yemhando yejoint uye yakavharwa ne insulating rubber gasket, pane yekudzivirira yejoini yega yega 4-6 metres.
♦Kupokana nekuora kunokonzerwa nemagetsi emagetsi
Sezvo ductile iron ine yakanyanya kusimba yemagetsi kuramba, iko kuramba kukora kunokonzerwa nemagetsi ikozvino.
