Cast concrete link pipes with plastic inliner as a world premiere

Schlüsselbauer Technology GmbH & Co KG, 4673 Gaspoltshofen, Austria


The Perfect Pipe system, realized in Germany in 2012 and comprising concrete and reinforced concrete base pipes of the nominal widths DN300 to DN600, constituted a world premiere. The pipes equipped with HDPE inliners with identical cross sections are manufactured at the Müller concrete works from DN250 to DN600 in the standard construction lengths 3 m and 1 m. Link pipes with special lengths can be manu- factured for both types – with or without inliner – in construction lengths from 1 m to 2.5 m. The final length of link pipes delivered ex con- crete works can be determined individually by the customer and what will in future reduce the shortening of standard pipes on site. In the past, the cutting to length of pipes with flexural rigidity on the construction site was frequently one of the weaknesses of pipeline construc- tion. Installation was interrupted; the joints of the pipes shortened on site did not always correspond to the quality of the standard pipe joints. The flexibility associated with manual adjustment of construction length compromised the total quality of the pipeline.
