With the increasing success of PE100 and usage of pipes of increasingly large diameter, concerns have been raised about the quality of weld performance with relatively thick walled pipes (>50mm), which has led to the current investigation. In addition to the consideration of welding conditions adopted in the UK, Europe and North America, Bodycote PDL has reviewed the testing conditions specified in each location. The result of the study is a comprehensive review of butt fusion welding and testing that provides a clear recommendation for optimum weld performance and testing requirements. The information presented also provides an opportunity to harmonise welding conditions and testing within standards across the continents of Europe and North America.
