PE Pipes for Contaminated Land [PE]

# 1998 Gothenburg

Polyethylene has many virtues as a material for underground potable water hstribution pipes. Unlike ferrous metals, it is totally immune to corrosion, and is extremely resistant to chemical attack from any aqueous media. However it has one minor weakness - it is slightly permeable to hydrocarbons, and other organic species. When buried in former industrial land that is contaminated with these materials, minute quantities may penetrate the pipe wall and generate undesirable taste and odour to the delivered water. This is still a very uncommon event, but legslation and increasing environmental pressure to preserve the countryside and re-use former industrial land in city areas, plus a need to pre-empt a less desirable alternative, has g v e n emphasis for a solution.

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...
