HOBAS Newsletter "PipeLine" 2010/02

Helleren hydropower station is situated along the Helleren River north of the polar circle between Narvik and Harstad in Norway. Its wooden penstock DN 2500 has been in service since 1958 and has reached the end of its lifecycle. Hålogaland Kraft AS, one of the numerous Norwegian electricity companies that base their business on 100% hydropower, opted for a long term durable and maintenance free HOBAS CC-GRP HydropowerLine DN 2500, PN 6 to replace the penstock.

The Romanian highway and road company CNADNR (Companiei Naţionale de Autostrăzi şi Drumuri Naţionale din România) is currently establishing the highway A3 between Romania’s capital Bucharest and the Hungarian border.

In Ip, a village in the northwest of the country, the highway crosses an old pipeline. During floods the line conveys large amounts of stormwater which also contains pieces of wood, silt and sharp stones.

The line had to be replaced and the road company went about searching for a suitable material, durable enough to withstand the abrasion and to improve the water discharge.

After a thorough comparison of materials and basing their choice also on past experience CNADNR and the engineering company opted for HOBAS Products.

The available range of diameters, the leak tight couplings, the pipes’ excellent hydraulic properties as well as their corrosion and abrasion resistance convinced the client to have found the optimal solution.
