Objectives
The primary objectives of this stage are to:
  • Conduct a gap analysis to compare the requirements of Standards that selected fittings conform to, with the requirements of established UK Gas Industry Standards
  • Demonstrate, under laboratory conditions, the assembly of all mains-to-meter mechanical fittings from 4 different manufacturers and compare against a conventional electro fusion mains-to-meter assembly
  • Undertake laboratory tests of selected fittings for both leaktightness and pull-out resistance
  • Undertake a cost benefit analysis and undertake field observations.
Expected Benefits:
The processes and outputs from tasks presented in this proposal will be documented in a final technical report and accompanying cost benefit model in Microsoft Excel format. Also included will be a digital video file showing the construction of laboratory test assemblies.

The success criteria of the Project are:
  • Efficiency - How does the process perform in terms of cost, and customer impact
  • Effectiveness - Can the solution be deemed safe over the life of the asset
  • Practicability - Is it practical and easy to adopt and what are the training requirements.
Abstract Since the mid 1980s the primary method of jointing small diameter PE pipe in the Gas industry has been by use of electrofusion sockets. This technique requires careful surface preparation, together with the associated electrofusion equipment and adherence to procedures, in order to affect a high integrity joint. National Grid Gas (NGG) is looking to investigate whether cost reduction and productivity improvements could be achieved by introducing alternatives to electrofusion fittings.
