Buried Flexible Pipes Behaviour In Unreinforced And Reinforced Soils Under Cyclic Loading

In this research, large-scale fully instrumented laboratory tests were conducted to investigate the behaviour of flexible high-density polyethylene (HDPE) pipes, in unreinforced and geogrid-reinforced sand, subjected to incrementally increasing cyclic loading; for example, due to different vehicle capacities or load increase with passing time. Results illustrated that the deformation rate in the pipe and footing, the strain generation […]

Large pressure pipe system – Fully PE100

Sverre Tragethon, Martin Andersson Papers # 2018 Las-Vegas Global mega trends push for investments in sewage treatment capacity & efficiency. A trend is to go for central regional treatment sites, typically remotely located from dense populated cities. This calls for high capacity pressure sewage transmission pipelines. Reliable operation is of course of paramount importance for […]

WHY CHOOSE HDPE CORRUGATED PIPE

“Flexible” pipes (made of PE, PP, PVC and HDPE) are able to satisfy all the initial project needs in a more efficient manner due to the thermoplastic material characteristics. These characteristics can easily solve general work site problems because they are durable, chemically resistant and last but not least, easy to handle. The “rigid” ones […]

Antioxidant Depletion In High-Density Polyethylene Pipes Exposed To Synthetic Leachate And Air

Authors: R.P. Krushelnitzky1, and R.W.I. Brachman2 ABSTRACT: Antioxidant depletion rates are reported for samples of one particular high-density polyethylene pipe when immersed in air and a synthetic municipal solid waste leachate, obtained by measuring the oxidative induction time (OIT) at temperatures of 22°C, 40°C, 70°C and 85°C with time. Of the factors examined, the rate of antioxidant depletion […]

The Structural erformance of flexible pipe for landfill drainage

Authors: D. F. Rogers, BSc, PhD, CEng, MICE, MIHT, Eur Ing, , The structural performance of perforated plastic pipelines used for landfill drainage is difficult to predict. This paper aims to describe their structural action on the basis of field measurements, and thereby make recommendations for their design and installation. The key requirements for structural support […]

Stress Concentrations Around Circular Holes in Perforated Drainage Pipes

Authors: R.W.I. Brachman, , and R.P. Krushelnitzky, Stress concentrations around circular holes in perforated buried pipes obtained from three-dimensional elastic finite element analysis are presented. The maximum stresses around the perforation were found to depend on the thickness and diameter of the pipe, the diameter of the perforation, the circumferential location of the perforation, and the axial and circumferential […]

Liner Buckling in Profiled Polyethilene Pipes

A.S. Dhar, , and I.D. Moore, Thermoplastic pipes are often manufactured with profiled walls to maximize the flexural stiffness of the pipe for a given amount of polymer. Thin elements in the profile can buckle under the influence of large earth pressures associated with deep burial or other extreme loading conditions. Earth load tests have been […]

Earth Pressure Measurements On Buried HDPE Pipe

Authors: M.L. TALESNICK*, H.-W. XIA†, and I.D. MOORE† An understanding of the stress distributions that act on buried pipes plays a key role in the development and use of design methods for these structures. The radial stresses that develop on buried flexible pipes have been investigated by a number of researchers through experimental, analytical and numerical methods. […]

Compaction Effects On Strains Within Profiled Thermoplastic Pipes

Authors: W. I. Brachman1, , I. D. Moore2, , and S. M. Munro3, Results from laboratory tests are reported to establish how pipe deflections, strains and local bending are influenced by the selection of backfill soil and its placement for two profiled thermoplastic culverts. Lined-corrugated high-density polyethylene (HDPE) and poly vinyl chloride (PVC) pipes with a nominal […]
