AKVA group has one of the most modern production lines for polyethylene pipes in Europe and thousands of kilometers have been delivered since 1971. 

The pipes are straight pressure pipes made from HDPE raw materials especially suited for continuous use in harsh environments, and are based on decades of experience in pipe technology. Polarcirkel polyethylene pipes are available in a wide range of models, shapes and sizes to suit individual needs and offer many benefits over competing systems, including: No corrosion or decay caused by the electrolytic process and no risk of material deterioration as algaes, bacterias or multicellular organisms are not able to stick to the pipe. Polarcirkel pipes are produced according to NS-EN 12201 and fullfill the requirements in the INSTA-CERT certification system.

More than 40 Polarcirkel pipeline projects have been delivered for hydro power plants since 1990, with up to 900mm OD and a maximum pressure of 20 bar. We can also calculate and optimize the pipe dimension and pressure according to the required waterflow. PE pipes have an extremely smooth interior surface that enables very good flow properties. Additionally, stub ends and flanges supplied to powerplant projects are specially designed for high pressure.
