Socket and Spigot Flexible Joints are assembled with synthetic rubber gaskets of special shape - the gasket has a hard ‘Heel' and a soft 'Bulb'.
For overground application and for fixing appurtenances Flat Faced Flange Joints are used.
Restrained Joints eliminate use of concrete anchor blocks and are necessary on fittings and a few pipes adjacent to the fittings. These special joints are made with Bolts and Glands to provide axial restraint.
This is a special Restrained Joint System (Known as Electrolock Joint) which is boltless and can be used for trenchless laying. For pipes cut at site, Electrosteel offers special Clamp Rings which eliminate the requirement of putting Weld Bead at site.
Thrust restraint is achieved by specially designed gasket with embedded steel teeth which performs the dual role of water sealing and restraining.
