The Challenge
As gas distribution networks (GDNs) modernise their infrastructure, it’s common practice for new polyethylene (PE) pipes to be inserted into redundant metallic pipelines. This method simplifies the process of laying new pipework and reduces excavations.
If a customer wishes to move the position of their gas meter (or a new connection is required), there’s currently no safe method to access the PE pipework in the old metallic pipes.
To do this, it’s necessary to access the PE pipe at the closest point where it isn’t encased (usually at the parent main, which are often found near or under main roads). To access these pipes, excavations will inevitably require more resources, materials and time, plus result in increased disruption and cost.
The Solution
Steve Vick International have developed an innovative new Service Window Cutter tool, which has been thoroughly tested at Gas Networks Ireland’s training school.
The tool is designed for use on 1″-2″ diameter pipes and will remove a section of the outer metal, without damaging the inserted PE pipe. This will enable operatives to modify services to a property quicker, with minimal disruption.
Approach
The project originated from an EIC call for innovation. The EIC supported the development of a project plan before being started in 2021.
Steve Vick have successfully developed functioning prototypes that have been tested by GNI operatives at their training school.
