There are up to three water supply pipe lines for the basins with different temperatures to create optimized conditions for healthy fish. Due to the positive experiences regarding installation, leak tightness and cost savings due to less maintenance, two large fish farming projects in the region of the Lofoten specified AGRU-SURE GRIP for the lining at their concrete basins which were done by in-situ construction in 2008.īesides the concrete protection also the piping systems out of PE 100 shall be mentioned, as some kilometres of water supply lines are installed for such fish farms. Several other companies were observing the performance and in 2007 some smaller projects were realized. For the project, which was managed in close cooperation with our distribution partner, precast elements with AGRU-SURE GRIP lining were manufactured in a precast production plant and shipped to the site by sea freight as delivery on road or an in-situ construction were not possible due to economical aspects. White polyethylene AGRU-SURE GRIP concrete protective liners (3 mm, specially formulated with food grade and UV-stabilized) were supplied. In 2006 the first installation at a fish farm in Salsbruket (Norway, Nord-Trøndelag) was realized. During high-pressure cleaning blistering and an increase of roughness of the lining occurred. Those basins out of concrete with typical adhesive coating systems did not perform well and repair intervals were quite short. The operators of such fish breeding farms were looking for alternative lining systems regarding better maintenance performance and non-toxic components for the fish and also for human beings. Due to overfishing of the oceans, several kinds of fish are threatened with extinction.įor Norway salmon farms are an important economic branch of industry. Pioneering trade fair appearances at AGRUįor several countries fish farms are an essential industrial factor.WELDING SYSTEMS More than 25 years accumulated experience in infrared welding technology for all AGRU piping systems: PE 100-RC, PP-H, PP-R, PP-Pure, Polypure, PVDF, PVDF-UHP, ECTFE, PFA, Poly-Flo, HV-liner piping system.
