Evaluation of the Notched Ring Test as a Means of Predicting the Long Term Performance

Harnett, Wilson

Testing and Processing # 1985 York

Notched ring sections of extruded pipe and injection moulded fittings have been tested to induce brittle failure which can be described by LEFM theory. Failure times have been measured at a range of applied stress intensity factors for each material tested at 23~C. The influence of processing, batch/batch variation in a material and pigmentation have been investigated. Comparisons of notched ring test results have been made with 8O~C stress rupture performance.

Polyethylene (PE) based and metallic pipe systems have been assessed for their ability to stop petrol migrating through the pipe wall, fitting or joint and into water contained within the pipe. A quantitative test was devised that is capable of distinguishing between the different pipe systems. Plain PE pipe...

2004 Milan : 20+ Years Experience with PE Pipe for Water in the UK

Author(s) : Headford, Hill, Wilson

The United Kingdom is the most highly developed PE pressure pipe market in the world. Following pioneering work done in the USA and Germany, it was the UK that was first to adopt PE on a large scale for gas, and then for water distribution. The 100% PE policy of British Gas, and wide range of sizes used (at low...

2001 Munich : Butt Fusion Welding of Large Diameter/Thick Wall Pipes

Author(s) : Hill, Wilson, Headford

Butt fusion welding is the most reliable and unobtrusive method of joining PE pipes (and spigot fittings) of virtually any size-except perhaps the smallest where other methods are usually preferred. It is the dominant method of jointing both medium and large pipe sizes, but for different reasons. In medium pipe sizes...

1995 Edinburgh : Verification of butt fusion weld quality in large diameter PE100 water pipes

Author(s) : Wilson

The &ect of pipe wall thickness and welding parameters on the joint quality of bun fusion welded PElOO water pipes has been investigated using notched Charpy impact testing and tensile testing. The conventional U.K. Water Industry weld tensile test does not give a geometry independent measurement of weld ductility but...

1988 Bath : The Behaviour of a Multilayered GRP Pipe when Subject to Local Attachment and Fluid Loading

Author(s) : Tooth, Banks, Wilson

An outline is given of the main processes employed for the manufacture of multilayered GRP pipes intended for the conveyancing of both water and contaminated fluids, where high strength and light weight lead to cost and/or transportation benefits. The analysis presented, which is based on Sanders’ thin shell theory...
