Pipe bursting in Norway: 900 m ductile cast iron pipe ND 600 replaced with HD-PE pipe OD 710
Feb 21, 2012
In Trondheim, Norway’s third largest City, or to be more precise in Gamle Jonsvannsheien, an ND 600 drinking water transport pipeline, made of ductile and grey cast iron, had to be renewed over a total length of 900 m. The pipeline, originally installed in the late 60s, showed definite signs of wear. Leaks, caused by corrosion and requiring elaborate repairs, were regularly occurred. To assure the water supply for the City it was decided that it was time to renew the 40 year old pipeline. In undertaking this replacement it was absolutely necessary to maintain the pipe’s original cross section. Due to the prevailing soil conditions an HDPE pipe of 710 OD x 52.2 mm wall thickness (with coating) was chosen as the new pipe.
