Due to changing weather conditions, UNICOR, a Germany-based corrugator specialist has claimed that there is an increased need for tunnel-shaped pipes in drainage systems. This is particularly apparent in countries where there is very little regular rainfall, but occasional heavy downpours.
Tunnel-shaped drainage pipes are mostly made from PVC since plastic provides high annular rigidity. The flat bottom of the pipe in contact with the soil makes for much better drainage than single walled pipes with fully circular corrugation.
To meet this demand for plastic tunnel-shaped pipes, UNICOR GmbH of Hassfurt in Lower Franconia has developed new machinery for producing corrugators. The newly developed perforating process allows these machines to produce tunnel pipes at a rate of up to 11 meters per minute. The company says this is twice as fast as previous production speeds.
Another benefit of the corrugators, which are named UC 250 and UC 315, is that at constantly high speeds the sockets can also be produced inline. This dispenses completely with the need for a separate production step involving additional time and cost.
New plants for these products are now being installed in areas throughout Southern Europe, UNICOR claims.
