Rubber Gasket
The absence of sunlight and oxygen, presence of moisture/water, relatively lower and uniform surrounding temperature in buried conditions help in preservation of rubber gaskets. Thus this type of joint is expected to last for more than 100 years.
– Good qualily Synthetic rubber gaskets made either of SBR (Styrene Butadyne Rubber) or EPDM (Ethylene Propylene Dimethyle Monomer) conforming to IS:5382 are used with Ductile Iron push-on ioint pipes.
– Gasket should be stored in a cool & dry place. Direct exposure to sunlight should be avoided.
– It is advised that the users should obtain gaskets through Electrosteel only.
Jointing Tips
– The sockets should face uphill while pipeline is laid on a slope.
- The direction of flow has nothing to do with direction of the socket.
- Never use petroleum based lubricant during jointing.
- It damages the gasket. Liquid soap solution or organic grease may be used.
- All Fittings should be suitably anchored against displacement as recommended in the laying specification.
- Spigots should be inserted into the socket upto the white insertion mark to ensure proper jointing.
- The joint deflection should not be more than the recommended deflection.
