To identify suitable resins supplied by 3M to establish if these could be used for services with lengths up to and over 20m. This resin this will then be used to investigate the concept of applying sufficient polymer to the service pipe and remotely jointing that polymer to a similarly applied (PRISM) polymer within the mains pipe to form a sufficient and acceptable fully structural pipe system. In parallel to understand if the BAE solution could be deployed earlier than the full PRISM solution as a quick win for the replacement of steel services, ideally using a single pass solution.
To support the development and delivery of a safe and efficient suite of processes, tools and techniques to join gas services to mains that significantly reduces the need for the excavation and reinstatement element of existing processes and thereby significantly reduce the costs and customer and stakeholder inconvenience and disruption.
This trial will provide a proof of concept for future trials on service to main connection techniques to expedite commissioning of projects correctly targeted at accelerating the delivery of a commercial solution
Satisfactory evidence to support the service replacement to main connection technique and results that enable us to continue to the next steps towards a commercial solution.
