Uhlolojikelele lwe-Ductile Iron Pipes
Sekuyiminyaka engaphezu kwengama-70 kwasungulwa ipayipi le-iron ductile ngeminyaka yawo-1940. Ngamandla ayo aphezulu, ubude obuphakeme, ukumelana nokugqwala, ukumelana nokushaqeka, ukwakhiwa okulula nezinye izici eziningi ezinhle, ipayipi lensimbi elidonsa amanzi liyisinqumo esingcono kakhulu emhlabeni wanamuhla sokudlulisa amanzi negesi ngokuphepha. I-Ductile iron, ebizwa nangokuthi i-nodular iron noma i-spheroidal graphite iron, ibonakala ngokuba khona kwe-spheroidal graphite ekubunjweni okuwumphumela.

Izinhlamvu ze-Ductile Iron Pipes
Amapayipi ensimbi akhiwe ngensimbi atholakala kububanzi obuhlukahlukene ukusuka ku-80 mm kuya ku-2000 mm futhi afanele kokubili ukudluliswa nokusatshalaliswa kwamanzi aphuzekayo (ngokuhambisana ne-BS EN 545) kanye nepayipi lendle (ngokuhambisana ne-BS EN 598). Amapayipi ensimbi e-Ductile alula ukuhlanganisa, angabekwa kuzo zonke izimo zezulu futhi ngokuvamile ngaphandle kwesidingo sokubuyisela okukhethiwe. Isici sayo sokuphepha esiphezulu kanye nekhono lokwamukela ukunyakaza komhlaba kuyenza ibe into efanelekile yepayipi yezinhlelo zokusebenza eziningi.
Amabanga Epayipi Lensimbi Yensimbi Esingayinikeza
Ithebula elilandelayo libonisa wonke amabanga ensimbi ye-ductile ezweni ngalinye.If ungowaseMelika, ungakhetha 60-40-18, 65-45-12, 70-50-05 njll., uma ungowase-Australia, ungakhetha 400-12, 500-7, 600-3 njll.

I-Ductile Iron Applications
I-iron Ductile inamandla amakhulu kanye ne-ductility kune-iron empunga. Lezo zakhiwo ziyivumela ukuthi isetshenziswe ngempumelelo ezinhlobonhlobo zezinhlelo zokusebenza zezimboni, okuhlanganisa ipayipi, izingxenye zezimoto, amasondo, amabhokisi amagiya, izindlu zamaphampu, amafreyimu emishini embonini yamandla omoya, nokunye okuningi. Ngenxa yokuthi ayiqhekeki njenge-iron empunga, i-iron ductile nayo iphephile ukuthi isetshenziswe ezinhlelweni zokuvikela umthelela, njengama-bollards.
