Ipayipi le-iron ductileiwuhlobo lwensimbi ye-iron-carbon alloy nodular cast iron, enemvelo yensimbi, ukusebenza kwensimbi, ukumelana nokugqwala okuhle kakhulu, i-ductility enhle, umphumela omuhle wokuvala, ukufakwa okulula, okusetshenziselwa ikakhulukazi amabhizinisi kamasipala wezimboni nezimayini ukuze kutholakale amanzi, igesi, uwoyela nokunye. Ipayipi lensimbi elidonsa amanzi liyindlela engcono kakhulu yokukhetha ipayipi lokuphakela amanzi, futhi linokusebenza kwezindleko eziphezulu.
Udonga lwangaphakathi lufakwe udaka lukasimende. Lapho amanzi anothe ngama-ion e-magnesium edlula, ama-ion e-magnesium azokhiqiza umphumela we-magnesium iron spinel futhi enze uqweqwe lwefilimu kusimende, acekele phansi i-colloid emanzini futhi avumele i-calcium ne-magnesium ions ukuthi igcinwe. Ngakho-ke, kungabonakala ukuthi inendawo yokunciphisa ukukhula kwesikali futhi akulula ukukala. Isikhathi esingaphezu kwezikhathi ezinhlanu kunokuphila kwesevisi yepayipi evamile. Ikakhulu isetshenziselwa ukuthuthwa kwengcindezi yamanzi kamasipala negesi.
Uma kuqhathaniswa nepayipi elivamile, ngokombono wekhwalithi, ipayipi yensimbi ye-ductile inezinzuzo ezimbili eziyinhloko, enye iyimpilo ende yesevisi, enye iwukumelana nokugqwala okuqinile. Kafushane, okungukuthi, ngaphansi kokufaka nokwakhiwa okulungile kwekhwalithi yamanzi kanye nezimo zesevisi, impilo yesevisi yepayipi yensimbi ye-ductile ingafinyelela eminyakeni engu-50, futhi ukugcinwa kulula kakhulu. Bese kuba nenkinga yentengo, kunezici ezengeziwe okufanele zicatshangelwe.
Ipayipi lensimbi elidonsa amanzi liwuhlobo lwepayipi eliphephile nelithembekile ohlelweni lokuphakelwa kwamanzi kanye nohlelo lokudonsa amanzi kuwo wonke amadolobha. Ipayipi yensimbi eyi-nodular ifaneleka kakhulu ukusetshenziswa endololwaneni, e-tee nasekuxhumekeni kwe-flange okuhambisanayo. Lapho kufika ihlobo, ubuso bepayipi lensimbi elicijile le-nodular kulula ukwenza ukungcola okukhudlwana kanye nongqimba olumnyama lwe-sludge olumpunga, oluzokwandisa ubunzima bokuhlanza ipayipi, futhi kubangele ukunqwabelana komlotha nokukalwa kwepayipi.
