Overview of Ductile Iron Pipe

Ductile cast iron, also called ductile iron, spheroidal graphite iron, or nodular cast iron, is a type of cast iron invented in 1943. While most varieties of cast iron are brittle, ductile cast iron is much more flexible and elastic, due to its nodular graphite inclusions.

Graphite particles exist in the form of sphericity in ductile cast iron. Sizes graphite particle are restricted to 6 -7 class and spheroidizing rate should not be less than 80%. Thus after the spheroidizing process, ductile iron will be endowed with mechanical properties of both cast iron and steel.

Much of the production of ductile iron is in the form of ductile cast iron pipe, used for water supply and sewerage design. Ductile cast iron pipe is stronger and easier to tap, requires less support and provides greater flow area compared with pipes made from other materials like PVC, concrete, polyethylene or steel. Ductile Iron Pipe is the most widely-used pipeline product in water supply and water drain/sewage projects.

Self-restrained Joint

Self-restrained Type is a push-in self anchored joint. The principle of joint anchoring consists in transmitting the axial forces from one pipeline to the following one, thus ensuring that the joint does not come apart.

The application of self-restrained joints is of particular interest where congested conditions preclude concrete anchor block constructions or in poorly cohesive soils.Self-restrained joints combine the advantages of flexible joint pipes and welded joint pipes.
