Compact Pipe - Close fit lining with PE pipes [PE]
# 1995 Edinburgh
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
Compact Pipe is a specific close-fit pipe lining
technique for various damaged utilities, ranging
from sewer mains to gas, water and industrial
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
This paper describes the actual performance of
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-...
