Mhedziso yeDuctile Iron Pipes
Pave nemakore anopfuura makumi manomwe kubva pakugadzirwa kwepombi yesimbi ye ductile muma1940.Nesimba rayo rakakwirira, kureba kwakakwirira, kuramba kwecorrosion, kuramba kuvhunduka, kuvaka kuri nyore uye zvimwe zvakawanda zvakanaka, ductile iron pombi ndiyo yakanakisa sarudzo munyika yanhasi yekufambisa mvura negasi zvakachengeteka.Ductile iron, iyo inonziwo nodular iron kana spheroidal graphite iron, inoratidzwa nekuvapo kwe spheroidal graphite mune zvinoguma zvekukanda.

Hunhu hweDuctile Iron Pipes
Ductile iron mapaipi anowanikwa muhupamhi hwemadhayamita kubva pa80 mm kusvika 2000 mm uye akakodzera kufambisa nekugovera mvura inonwiwa (maererano neBS EN 545) uye tsvina (maererano neBS EN 598).Ductile iron mapaipi ari nyore kujoinha, anogona kuiswa mumamiriro ese ekunze uye kazhinji pasina kudikanwa kwekudzoserwa kwakasarudzwa.Yayo yakakwirira yekuchengetedza chinhu uye kugona kugadzirisa kufamba kwepasi kunoita kuti ive yakanakira pombi zvinhu zvemhando dzakasiyana dzekushandisa.
Magiredhi eDuctile Iron Pipe Isu Tinogona Kugovera
Tafura inotevera iri kuratidza ese magiredhi esimbi echigadzirwa chenyika imwe neimwe.Ikana uri muAmerica, saka unogona kusarudza 60-40-18, 65-45-12, 70-50-05 nezvimwewo, kana uchibva kuAustralia, saka unogona kusarudza 400-12, 500-7, 600-3 etc.
