DUCTILE IRON PIPE

Ductile iron is a family of cast iron. The difference between ductile iron and cast iron is in the graphite formation in the metal. Cast iron is characterized by a random flake graphite pattern. In ductile iron, the graphite form is small spheroids rather than flakes. This creates fewer discontinuities in …

The use of cast-iron pipe was introduced in the United States in the early 1800s. Since that time, various other piping materials have been offered for water distribu-tion. However, waterworks engineers continued to use cast iron until ductile iron, a stronger and equally durable piping material, became available. 1.1.2 Development of Joints ...

Compacted Graphite Iron Castings - Durham Foundry

Compacted Graphite Iron was first patented at about the same time as ductile iron in the late 1940's. At the time it was viewed more as a curiosity rather than a production material, but its unique properties has led it to be used in many applications which are unsuitable for grey or ductile iron.

Standard Specification for Ductile Iron Castings

1.1 This specification covers castings made of ductile iron, also known as spheroidal or nodular iron, that is described as cast iron with the graphite substantially spheroidal in shape and essentially free of other forms of graphite, as defined in Definitions A 644. 1.2 The values stated in inch-pound units are to be regarded as the standard.

A Guide to Ductile Iron

A Guide to Ductile Iron. The so-called "iron instead of steel" mainly refers to ductile iron. Ductile iron is obtained through spheroidization and conception treatment, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness, and thus obtains higher strength than carbon steel.
