Ductile Iron Pipes, Iron Pipe

Ductile Iron retains the corrosion resistance of Cast Iron but has more than double the tensile strength [Cast Iron- 180 MPa (min), Ductile Iron - 420 MPa (min)]. The essential difference between Ductile and Cast Iron lies in the shape of the graphite in the microstructure of the metal. In Cast Iron, the graphite is present in plate-like flakes, which makes Cast Iron brittle. But in Ductile Iron, the shape of the graphite becomes a spheroidal nodule, which offers better mechanical properties and makes Ductile Iron sturdy, structurally stronger and shock-proof.

Ductile Iron (also known as Spheroidal Graphite Iron or Nodular Cast Iron) was invented in 1949. Ductile Iron retains the corrosion resistance of Cast Iron but has more than double the tensile strength [Cast Iron- 180 MPa (min), Ductile Iron - 420 MPa (min)]. The essential difference between Ductile and Cast Iron lies in the shape of the graphite in the microstructure of the metal.

Socket and Spigot Flexible Joints are assembled with synthetic (Ethylene Propylene Diene Monomer Styrene-Butadiene-Rubber) rubber gaskets of special shape. The gasket has a hard ‘Heel’ and a soft ‘Bulb’. In Push-on joint the soft bulb of the rubber gasket is compressed when the spigot is inserted into the socket. The ‘Heel’ locks the position of the gasket and does not allow the gasket to get displaced when the spigot is pushed in. The joint becomes tighter with the increase in internal pressure of water. The rubber is confined in a place and cannot blow out.
