2014 Chicago : A Training and Certification Standard for Fusion Welding of PE PipesAuthor(s) : Edward Ingham, Mike Shepherd
Exova has previously demonstrated that under normal operating conditions PE 100 pipes would be expected to have a lifetime of over 200 years, but in the UK concerns have been reported about relatively high failure rates within the water utilities of fusion joints, particularly for large diameter pipes. For some time,...
2006 Washington DC : Development of a Whole Life Costing Model for Large Diameter Water MainsAuthor(s) : Shepherd, Headford, Jordan, Reeves, Walton
In Europe polyethylene (PE) has been chosen almost exclusively for gas mains for many
years because of economic, technical and safety reasons but in the water industry a number of
different materials are still used for pressure water mains. Indeed at sizes above 355mm (14
inch) most new large diameter water mains are...
2006 Washington DC : Replacing London's Victorian Water MainsAuthor(s) : Becker, Shepherd
In common with most other major cities around the world, London has grown outwards from
the centre as its population has increased. What may not be appreciated is that this holds true
not only for the roads and buildings but also for the buried infrastructure, particularly the
water mains and sewers, which were the...
1998 Gothenburg : Plastic Pipeline SystemsAuthor(s) : Shepherd
This presentation is written from the perspective of the water industry and is therefore mostly concerned with pressure pipes for potable water as this is far and away the biggest area of use of plastic pipe systems.
The Water Industry has been constructing its pipe network for over 150 years and it has been estimated...
