Structural Behaviour of Thin-Walled Plastic Pipe Linings for Water Mains [PE]

Author(s) : Boot 2004 Milan

Flexible (non-bonded) polymeric linings are used extensively to renovate both gravity and pressure pipes. Linings for both types of pipe are subject to collapse pressures, and in the case of gravity pipes this is the dominant source of loading; the efficient design of linings to sustain collapse pressures is therefore...

The principles underlying the concept of thermoplastically lined pipes for untreated well-head fluids, with particular reference to subsea applications, are first described. The prime sources of load on the lining are then identified as build-up of gas pressure in the pipe-lining annulus and swell of the lining. Since...

The fundamental structural characteristics of cured-in-place pipe for sewer linings are first described, and current procedure for their design reviewed. Following identification of the major inconsistencies in this design philosophy, a programme of research with the objective of addressing these issues is summarised....

The Philosophy underpinning the concept of a polyethylene pipe lining designed to span small corrosion voids and longitudinal gaps in the host pipe is outlined, and provisional performance graphs for MDPE systems are given which indicate the potential savings that can be made under appropriate circumstances. Work...

This paper summarises current design practices for buried thermoplastic pipelines subjected to combined gravity and internal pressure loadings. It suggests that accurate predictions of stabilised deformations are neither possible nor necessary, but that appropriate structural design methodologies should instead...
