Pipelines, as used for their various applications appear to suffer frequently from deterioration. The combination of new products and advanced plastics materials ensures that pipe renovation can be carried out with increasing efficiency and decreasing environmental disturbance. Methods of renovation that currently enjoy particular interest are the so-called close-fit lining techniques. They provide the existing pipeline with a structural plastic pipe lining in such a manner that the annular space between the two is minimal, thus giving the most optimum flow conditions. Compact Pipe is a specific close-fit pipe lining technique for various damaged utilities, ranging from sewer mains to gas, water and industrial lines. The pipe itself is a continuous string of polyethylene pipe, folded into a '?-shape along its length. Case histories presented in this paper give evidence that Compact Pipe is a justified option for a wide variety of applications.

The type of problems encountered in existing pipelines are presented in this paper, together with the available methods to rehabilitate them. In the majority of the cases plastics are nowadays applied, either to replace the existing ones, or to renovate them by lining. The latter is increasingly gaining...

Today, in some parts of Europe plastics pipes and fittings are considered as mature products which have obtained an established position in underground applications. However, in others due to their flexible nature, their use is still sometimes questioned. This paper describes the actual performance of plastics pipes...

One of the main reasons that plastics have not found more extensive use in non pressure sewer schemes has been concern about the long term deformation characteristics of the pipeline. In order to investigate this phenomenon the flexural behaviour of u W C sewer pipes installed in Western European countries, including...

The main concern over the behaviour of buried plastics pipes is the occurrence of deflection.
