AN EVIDENTIAL APPROACH TO USE OF POLYETHYLENE PIPE FOR HYDROGEN FUEL GASES

Derek Muckle # 2021 Amsterdam A technical program has been undertaken to provide evidence on the suitability of polyethylene pipe and fitting systems for the distribution of hydrogen fuel gas. The underlying principle has been to evaluate material in the form of a pipe and to consider the performance of the pipe and of the welded jointing […]

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 […]

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 […]

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 […]

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 […]

LONG-TERM PERFORMANCE AND LIFETIME PREDICTION OF GEOSYNTHETICS

Y.G. Hsuan1 , H. F. Schroeder2 , K. Rowe3 , W. Müller4 , J. Greenwood5 , D. Cazzuffi6 , R.M. Koerner7 To properly understand and assess the long-term behaviour of geosynthetic materials it is necessary to investigate the various types of possible degradation mechanims. This includes both chemical and mechanical behaviour, and sometimes even their […]
