The scope of this Project is to further develop the ePIPE system (currently used within the water distribution industry) adapting it for use in the gas distribution industry, allowing internal risers inside high rise buildings to be coated internally so extending the operational life of the asset. The Project will ascertain what resin developments are needed, what equipment designs need to be altered and what procedural processes need to be implemented. The development of the ePIPE product will be an iterative process based upon the results of trial work The Project will:

  • Assess the technology in a mock/test environment and development of a specification

  • Develop and test the suitability of new resin formulations

  • Validate and develop a suitable industry standard.

The objective is to develop an internal resin and application system that could provide an elegant and cost effective solution. This would substantially decrease the replacement cost of a gas riser system.

The objectives of the Project are to:

  • Substantially improve the cost of the replacement of a gas riser.
  • Significantly increase the operational life of the asset.
  • Reduce the gas leakage on the system (small leaks only)
  • To avoid major construction work minimising transport and customer disruption.
  • Significantly reduce time on site
  • Establish training requirement and equipment needs
The success criteria of the Project are:

  • Efficiency - How does the process perform in terms of duration, safety or customer impact

  • Effectiveness - Has the lining provided complete and even coverage, including threaded joints

  • Practicability - What enablers are required in terms of customer cooperation, network isolation, other impacts?

  • Recommendations for suitability for refurbishment or replacement criteria by comparing to existing standards and identifying additional standards or amendments that may be required

  • Training needs – achieve acceptable training needs.

    Through-out the Project there will be monthly reports from Pipe Restoration Services , to update all Project steering group members on the progress of the Project. There will be face to face meetings every 6-8 weeks and key deliverables reviews at key points with accountable parties clearly identified. Each stage will have its own deliverables and targets which the Project will measure itself and report on monthly as it progresses. When issues are identified recovery plans will be adopted to ensure minimal impact on time scales, and avoid additional costs.
