Summary
Documents
Above ground trials of various technical solutions in a yard environment will be carried out, by deploying them in pipe and applying PRISM. The samples will then be inspected and tested by an independent consultant and a report issued.

A number of 25m runs of pipe will be subjected to PRISM application and 5m of technical solution testing, samples will then be taken for inspection and testing to derive the applied resin thickness profile along the length of the test sample.

Benefits
  • 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.
