welded and installed on site, can potentially save up to 90 per cent of transportation costs compared with extruded pipes. Bistable pipelines are equally useful in replacing and repairing low-pressure aqueous and non-aqueous applications.

Polypropylene pipes for smooth-flowing sewer project Borealis, a plastics solutions specialist, has supplied plastics processor Rehau with BorECO™ BA 212E, a highly developed polypropylene (PP) for pipe systems. Rehau was faced with the challenge of installing a smooth-flowing sewerage system in the residential area of Traiskirchen, Austria, during the winter season, and benefited from BorECO’s features, which include low weight, high stiffness, durability and good impact resistance even at low temperatures.

› The low weight of pipes made from BorECO PP allows fast and cost-efficient pipe laying

Mr Guido Kania, Rehau’s senior manager (research and development), commented, “ The wintry weather during installation plus the cold conditions facing the pipes once underground meant that a heavy duty solid wall pipe with high ring stiffness and good cold climate performance had to be used. In combination with the community’s demands for a sewer pipe system with good corrosion resistance and long-term performance, we felt that Borealis’ BorECO

was the ideal material to produce our Awadukt PP sewer pipe system. ” The low weight of pipes made from BorECO PP compared to traditional concrete pipes allowed the construction company fast and cost-efficient pipe laying in the trench, even for large pipes with thick walls. Smooth installation at the trench was assisted by the high ring stiffness and jointing flexibility of the finished pipes. Rehau used a safety-
