♦ Ductile iron yakasimba, inogona kutsungirira kushushikana kwemagetsi uye kushungurudzwa kwepanyama, inogona kuiswa munzvimbo isina kunaka uye mamiriro ekushanda uye kushanda pasina kukundikana kupa hupenyu hurefu hwebasa.
♦Ductile iron pipe, fittingsuye zvishongedzo zvinoshandiswa kutapurirana mvura inonwiwa nemvura yetsvina munzvimbo dzakati wandei dzakadai semambure emvura yekunwa, maseweji network, masisitimu ekudzima moto uye masisitimu emvura eHVAC.
♦ Kubatsira kwe ductile iron mapaipi uye fittings:
• High tensile simba, yakanaka elastic module uye yakanakisa ductility, ichiita kuti ive yakakodzera kune yakanyanya kushushikana maapplication uye uko kudzvanywa kwekuwedzera kunogona kuitika.
• High corrosion resistance.
• Yakanakisa hydraulic kuyerera.
• High kushanda kudzvinyirira kuenzaniswa nemamwe marudzi epombi.
• Kureruka kwekuisa.
• Hupenyu hurefu.
•Inogona kugarisa ground movement.
♦ Coating:
External coating:
TS EN 545 pombi: simbi zingi yekunamatira ine yekupedzisa layer
TS EN545 zvigadziriso: zinc yakapfuma pendi yekumisikidza ine yekupedzisa layer
BS EN598 pombi & zvigadziriso: epoxy pendi
♦ Internal lining protection
TS EN 545: sulphate inodzivirira simende dhaka lining
TS EN598: yakakwira aluminium simende yedhaka lining
