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

 

Plastic Pipes Conference Association # 1992 Eindhoven

Boot, Guan

The case for development of rational design criteria for thinwalled polyethylene pipe linings is argued. Progress to date on a programme of research formulated to meet this objective is discussed. Short and long term behaviour under stress is modelled using elasto-plastic and elasto-viscoplastic constitutive models based on extensive material testing. Finite element simulation of representative systems tested to failure in the laboratory, and the long term behaviour of field systems are described.

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...

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...
