Ductile iron is also referred to as nodular iron or spheroidal graphite iron by Ductile Iron Pipe Manufacturer. The ductile iron bell and spigot pipe are characterized by the presence of graphite in a nodular or spheroidal form as a result of casting. The main difference between cast iron and ductile iron is that the latter has greater tensile strength and significant elongation at break.
A reason why ductile iron pipe suppliers in Mumbai recommend using this metal is because of the numerous advantages it offers. For instance, The ductile iron cement lined pipe offers high resistance against breakage due to impact, in addition to corrosion resistance properties that are, comparable to that of cast iron. The is 8329 ductile iron pipe is also known to have a high tensile strength, which rivals that of mild steel grades.
This implies that ductile iron pipes could be used in applications involving higher working pressures. As compared to cast iron pipes, ductile iron pipes tend to be lighter in weight. The ductile iron pipe manufacturing process starts with the pouring of molten iron in a centrifugal cast against the inside wall of an externally cooled metal mould that rotates. The deLavaud casting process for a is 8329 for di pipe incorporates a metal mould which is known to have a peen pattern or design on its inside diameter. This peen pattern is transferred to the IS 8329 DI Pipe during the casting process. Requirements for coating as well as the lining of the di k7 & k9 pipes specifications have been modified.
