Live Fitting of Pipeline Isolation Valves

Call
GDN-19-02
Currently, there is no readily available method to insert a Pipeline Isolation Valve (PIV) onto metallic mains under live conditions.
 
The challenge in this area is to install this equipment without interruption to customer supply in the following circumstances:
• Where Installations require a method of isolation for use in an emergency, particularly prevalent for use on Multiple Occupancy Buildings (MOBs)
• To avoid the replacement of steel Riser systems with polyethylene once disconnected from the parent supply
