The scope of the project is to qualify Nu Flow’s small bore pipe lining/rehabilitation system on a live gas system as an interim remediation technique. The pre-work will also enable the construction project and post-completion; the learning will be taken and incorporated into the relevant policy documentation.

Project deliverables are:

  • Updated G/23 site trial document

  • Testing of proposed Copper-PE solution (lining, transitioning with a mechanical fitting, etc.)

  • Witnessing of construction project and collation of site data and evidence and most importantly further…
  • update of draft Riser Liner Specification Document

Successful delivery of this project will build on work previously completed and providing learning as to how this technology can be further applied practically. The data collected will also be used to augment the Riser Liner Specification.

The objectives are:

  • Further completion of policy documentation review to fully enable the technology on the Gas Distribution Network
  • Development and testing of NuLine product as part of an engineering solution to line copper pipe systems and connect/transition into MDPE (successful completion of this testing will increase the scope/range of application of the NuLine and similar products)
  • Further assessment of the performance of the NuFlow product in relation to the requirements of the riser liner specification; due cogniscance given to (consistency of application, wall-thickness, adhesion, pressure loss, design life, etc.)
  • Further Observation of operational processes which will enable the development of operational guidelines for implementation

Obtainment of qualitative and quantitative data and analysis for incorporation into policy documentation.

The project will be deemed a success by providing:

  • Successful completion of test programme and acceptance of outputs

  • Successful execution of construction project

  • Obtainment of qualitative and quantitative data from testing and site

Acceptance of updated policy documentation.
