Objectives To derive and demonstrate the thickness profile and variation of the applied resin over a 80m length of 4" pipe to determine the distribution curve over the length. To demonstrate the suitability and test identified solutions for dealing with joints, other features such as ferrules, termination of PRISM in the existing main and determine their effect on the distribution of PRISM application. To collate preliminary safety documentation to ensure that all required data is available to take the project forward into live trials. A demonstrated profile of PRISM application that can be used to determine the settings needed to maintain the minimum thickness required when in use on the network to ensure consistent structural strength along any applied length. A completed process of selection on which products to proceed with to the next stage to solve the technical challenges such as joint spanning and end mains connection. A draft "G23" document that highlights areas that will need development to proceed to live trials.
Abstract Current methods of replacing gas distribution mains are costly and disruptive to customers and road users. This initiative seeks to determine a method of achieving the outputs of mains replacement more efficiently. Utilising PRISM, the renewal of mains within a street could be possible via an excavation at each end of the street. This would result in a reduction in cost and effort, improved safety, environmental benefits through reduced waste to landfill and reduced customer and third party disruption, leading to improved customer satisfaction. This project will build on recent work outside of the NIA and has brought together suitable project partners and delivered a proof of concept method of applying a polymer to the inside of pipes with potential to satisfy gas industry requirements. Other similar projects have been undertaken over the past 10 years. The most successful of these being project FORGE; a scheme managed by both National Grid and Balfour Beatty. FORGE developed a process to rehabilitate gas mains through a replacement/rehabilitation technology previously adopted by the water sector. This phase of work is to further the development of the PRISM (Pipe replacement in situ manufacturing) technique, by identifying, developing and testing various technologies to solve specific technical challenges that gas mains present that are not faced in water mains.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
