PE flange HP

welding neck

HP flanges from Reinert-Ritz are high performance solutions for the full pressure resistance of a loose flange connection with a welding stub. A special PE100 welding stub and a loose flange-type backing flange adjusted to the dimension form a precisely coordinated unit and are permanently connected to each other. Here the stub and the flange interlock in a positive fit at their connecting surfaces in a similar way to a tongue and groove. The axial forces of the pipeline are transferred to the flange over the entire stub surface. This combination protects against deformation of the PE stub and, depending on the dimensioning, makes pressure loads of up to 25 bar possible. The backing flanges are available in a steel version with a plastic coating or in a corrosion-free and fibre-reinforced plastic version. The fittings to be offered must be delivered as a set consisting of a welding stub and a loose flange-type backing flange adapted to the dimension. The welding stubs must be manufactured from material in compliance with the PE100+ Association and according to DIN EN 12201 and DIN EN 1555 with respect to dimensions, tolerances and quality requirements. The backing flanges must be manufactured from corrosion-free, fibre-reinforced plastic or from steel with a plastic coating in accordance with DIN EN 10310. Proof must be provided that they were manufactured on the basis of a quality assurance system in accordance with DIN EN ISO 9001. For all fittings a certificate in accordance with DIN EN 10204 must be submitted by the manufacturer.
