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

 

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.

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.

Butt Fusion Welding of Large Diameter/Thick Wall Pipes

Author(s) : Hill, Wilson, Headford 2001 Munich

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...

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...
