A Flexible Solution for Renovation of Small Diameter Service Pipes

Author(s) : Derek Muckle 2016 Berlin

It has long been the case that plastic pipes have been subject of folding operations in a factory and then supplied to site for use in pipeline renovation applications. The same cannot be said for pipes subject to diameter reduction as they have, as a principle, relied on being diameter reduced at site in a forming...

Polyethylene pipe is being routinely used for the close fit lining of large diameter water trunk mains, with the twin objectives of improving water quality and reducing losses due to leakage. Trunk mains serve large urban areas and by definition are large diameter pipes; examples of real lining schemes in the past 12...

Polyethylene pipes are widely used across the utilities sector for the safe, reliable, transportation of gas or water under pressure. The success of the material in being adopted is partly due to the ability to treat it as an engineering polymer whose properties and failure modes are well understood, predictable, and...

For the movement of fuel gas and water, plastics pipes are dominant in many markets, and this success has been based on single material solid wall pipes. There are now an expanding number of multi-layered plastics pipes, and described here for the first time is the performance of the second-generation of skinned pipe...

The United Kingdom has one of the oldest and most developed gas transportation systems in the world. Today, its policy is to use polyethylene (PE) as the preferred material for the safe and efficient transportation of natural gas for operating pressures up to 7 Bar. Transco are the largest gas transporter in the UK...

In 1999 the Health & Safety Executive agreed to the introduction of a new risk based methodology to be used for prioritising iron mains replacement. The introduction of this methodology combined with the results of major incident investigations has led the Health & Safety Executive to conclude that the potential risk...

Transco, part of the Lattice Group, is the largest Public Gas Transporter in Great Britain. It currently operates a Distribution system of some 250,000 kilometers. Developments in polyethylene pipe technology have led to an ongoing increase in the size of pipe being laid in the U.K. Currently, pipes up to 630 mm...

Developed to address the practical problems experienced on site with the preparation of the surface of polyethylene (PE) pipes for electrofusion jointing, skinned PE pipe also offers the secondary benefit of general pipe protection against gouging and other forms of abrasion damage. This paper discilsses the concept...

During talks with personnel from Redlands Reinforced Piastics Ltd. (part of the Redland Group of Companies), the process of machining plastic reinforced pipe end-forms was discussed with a view to improving manufacturing efficiency. Traditionally Redlands manufacture 65% to 70% glass reinforced plastic pipes which are...
