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.
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-
