INTRODUCTION OF LARGE DIA PROFILED PE/PP PIPES FOR INNOVATIVE PIPED DISTRIBUTION NETWORK (PDN) FOR IRRIGATION IN INDIA

Author(s) : C. B. Dandekar 2018 Las-Vegas

Agriculture is the major occupation practiced in India, and irrigation is therefore a vital part of the entire water budget of the country. India possesses only 4% of the total world’s fresh water resource, of which, more than 80% is consumed solely in the Agriculture Sector (Dhawan, 2017). Canal based distribution...

INVESTIGATION OF THE CREEP FAILURE BEHAVIOR OF POLYAMIDE PIPES

Author(s) : Hiroto Taguchi, Kaori Numata 2018 Las-Vegas

We elucidated the creep failure behavior of polyamide pipes. We conducted the hydrostatic test and Notched Pipe Test (NPT) at 80 and 90 °C for up to 10000 h for PA pipes whose creep failure behavior has not been fully elucidated yet. In the tests, the change in the failure mode from ductile failure to brittle...

INVESTIGATION OF THE FAILURE BEHAVIOR OF POLYETHYLENE ELECTROFUSION SOCKETS

Author(s) : Isabelle J. Berger, Andreas Frank, Gerald Pinter, David Nitsche, Dirk Petry 2018 Las-Vegas

Electrofusion (EF) sockets constitute a well-established and practically proven technology for the joining of polyethylene (PE) pressure pipes. As for the pipes, the potential lifetime of such welding connections is beside other properties also depending on the resistance against slow crack growth (SCG). The current...

LABORATORY DEVICE FOR CHECKING THE THERMAL ENERGY DELIVERED BY THE ELECTROFUSION FITTINGS

Author(s) : Dominique GUEUGNAUT, Adil BOUJLAL, Aymeric LOPITAUX, Bertrand SEVRE 2018 Las-Vegas

A special concept has been developed by GRTgaz Research and Innovation Center for Energy (RICE) for temperature mapping at the interface of an electrowelded assembly.The technical solution consists of a tubular piece in place of the real PE pipe, made of a non-weldable polymer with thermal parameters close to those of...

LARGE DIAMETER SPIRAL WOUND PRESSURE PIPES

Author(s) : Bülent Kuzkaya 2018 Las-Vegas

Spiral wound pipes are becoming more and more important in larger diameter HDPE pipe production technology. The spiral wound structured wall pipes with profiles are already well known and used for several low or non-pressure pipe applications. This paper shows that spiral wound pressure pipes can fulfill the...

Large pressure pipe system – Fully PE100

Author(s) : Sverre Tragethon, Martin Andersson 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...

LITERATURE REVIEW: EFFECT OF ClO 2 ON AGEING OF POLYMER MATERIALS AND RELATED TEST METHODS

Author(s) : E.J.W. van der Stok, K. Jacobson, S.O. Jansma, D. Lukes 2018 Las-Vegas

The lack of a fast, universally-accepted test method for chlorine-dioxide-disinfected water is hindering the development of improved plastic piping materials. A literature survey was performed to define the degradation process in which chlorine dioxide affects the ageing of polypropylene, and to describe and reflect...

LONGITUDINAL CRACK IN LARGE PVC-U PRESSURE PIPES. PIPE GELATION INFLUENCE. CASE STUDY III

Author(s) : Joaquín Lahoz Castillo 2018 Las-Vegas

Irrigation networks in Spain extensively make use of plastic pressure pipes systems. Some recent failures focus the attention on Rapid Crack Propagation phenomena. Larger high-pressure PVC-u pipes are involved in most incidences detected. The level of gelation of those pipes were measured per EN-ISO 1452-2 test...

MODERN PE PIPE ENABLES THE TRANSPORT OF HYDROGEN

Author(s) : R.J.M. Hermkens, H. Colmer, H.A. Ophoff 2018 Las-Vegas

To investigate the suitability of PE pipes for the transport of hydrogen on a specific industrial site, three topics were investigated. These topics are: the chemical resistance of PE to hydrogen, the permeation rate of hydrogen through PE and the electrofusion of PE pipes exposed to hydrogen. It can be concluded that...

MOLECULARLY ORIENTED AWWA C909 PIPE FOR SEISMIC APPLICATIONS

Author(s) : Richard St-Aubin, Dr. Thomas O’Rourke, Dr. Brad Wham, Blake Berger 2018 Las-Vegas

Molecularly oriented polyvinyl chloride (PVC-O) pipe has been found to withstand large ground deformation during seismic events without damage. The properties of PVC-O pipe that support this performance have been investigated in a multi-year testing program undertaken at the Geotechnical Lifelines Large Scale Testing...
