Purge End Caps were designed for gas distribution systems to provide a connection point for two important functions:
- Pressure testing a polyethylene gas main
- Purging air from the gas main when gas flow is required
The Purge End Cap incorporates a non-return valve that provides a high volume discharge when purging. The non return valve system allows for disconnection of burn off equipment from a “live” gas installation.
Clare Purge End Caps are designed for electrofusion or butt welding to 63mm SDR11 pipe. For larger diameter pipe, reducers are used in conjunction with the Purge End Cap.
Purge End Caps are available in PE100 Black and are tested for leakage at 700kPa.
