Dedicated Solutions for Exceptional Pipe Materials - Considerations for the selection of adequate joining and repair products for GRP and concrete pipework

The article shows how to realise pipe connections and repairs of GRP-, concrete and fibre cement pipes. These pipe materials are more or less uncommon in the water supply. Their special characteristics and typical joining methods will also be illustrated. Piping network operators using these pipe materials may also be aware of the standard connectors often not to be very useful in case of maintenance and repair. Therefore, great importance should be placed on the analysis of the pipework. The authors display key factors for the professional technical evaluation of the pipelines, as well as they show current "trench-proven" solutions for the issues mentioned.
