Hydropower Station in Norway Received a Durable HOBAS Penstock
Bearing the wood’s disadvantages on mind, Hålogaland Kraft sought after a long lasting, durable and maintenance free replacement. These characteristics should apply for both, underground as well as above ground installed pipes on supports. A perfect match was found in HOBAS CC-GRP Pipes which serve all requirements and soon were the favored option of the power producer. Not only do they offer a long and maintenance free future, but maintain their outstanding properties whichever way they are installed. Be it above ground, without additional protection, or in soil, the UV and abrasion resistant outer surface protects the pipes’ properties and ensures durability. Their easy assembly through the simple jointing system promised a short construction time, which was seen as a further decisive plus. Since the storage area at the construction site was restricted, the DN 2500, PN 6 CC-GRP Pipes were partly delivered directly to the supports on site. This was possible thanks to the close and well functioning cooperation between the pipe supplier HOBAS, the client Hålogaland Kraft and the contractor SKANSKA. Once filled with water each pipe weighs 32 tons. This load is transmitted down into the ground by concrete supports.
