Bayanin Ductile Iron Pipe
Ductile Iron bututu bututu ne da aka yi da baƙin ƙarfe. Ƙarfin Ductile baƙin ƙarfe ne mai spheroidized graphite simintin ƙarfe. Babban matakin dogaro na ductile baƙin ƙarfe shine da farko saboda ƙarfinsa, ƙarfinsa, da tasiri da juriya na lalata. Ana amfani da bututun ƙarfe na ƙarfe don rarraba ruwa mai ɗorewa da yin famfo na slurries, najasa da sinadarai masu sarrafawa. Wadannan bututun ƙarfe sune haɓakar bututun ƙarfe na farko wanda a yanzu ya kusa maye gurbinsa. Babban matakin dogaro na bututun ƙarfe na ductile shine saboda kyawawan kaddarorin sa daban-daban. Wadannan bututun su ne mafi yawan bututun da ake nema don aikace-aikace da yawa.
