Plastic Pipes Conference Association # 2001 Munich
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 popularity. Attention will be given to particular design aspects of renovation (lining) with plastics pipes as well as the quality assurance of the liner in installed state.

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...

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. Theories are useless if not checked by field measurements to remove uncertainties, Over the last 15 years. 25 km of pipeline in 600 different sections have been measured in 5 West-European countries in quite different circum-...
