Zubar da bututun ƙarfe
Takaitaccen Bayani:
Bututun simintin ƙarfe yana nufin bututun simintin ƙarfe.Ana amfani da bututun ƙarfe don samar da ruwa, magudanar ruwa da bututun watsa iskar gas, gami da simintin ƙarfe madaidaiciya bututu da kayan aikin bututu.Ƙarfin aiki yana da ƙasa.Dangane da hanyoyin simintin simintin gyare-gyare daban-daban, an raba shi zuwa bututun ƙarfe mai ci gaba da simintin ƙarfe da bututun ƙarfe na simintin ƙarfe, daga cikinsu akwai bututun simintin ƙarfe na centrifugal zuwa ƙera yashi da ƙarfe.Dangane da kayan daban-daban, an raba shi zuwa bututun ƙarfe mai launin toka da bututun ƙarfe na ductile.A cewar daban-daban dubawa siffofin, shi ne zuwa kashi m dubawa, flange dubawa, kai anka dubawa, m dubawa, da dai sauransu.
