Factors Affecting the Use of PE Pipeline Materials for Large Diameter Water Mains [PE]

Shepherd

# 2004 Milan

Polyethylene pipeline systems have now been used with considerable success by the UK Water Industry for over twenty years. Most, if not all, water companies now regard polyethylene as the default material choice for all normal distribution system applications. i.e. up to 300mm nominal diameter. However, for larger diameter pipelines, polyethylene has not been nearly as successful in gaining market share. This paper attempts to explore some of the reasons why this is the case.

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,...

Development of a Whole Life Costing Model for Large Diameter Water Mains

Author(s) : Shepherd, Headford, Jordan, Reeves, Walton 2006 Washington DC

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...

Replacing London's Victorian Water Mains

Author(s) : Becker, Shepherd 2006 Washington DC

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...

Plastic Pipeline Systems

Author(s) : Shepherd 1998 Gothenburg

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...
