A special variant of the reduced tee is that with a level invert branch. This enables complete emptying of the pipeline. Conformity with the pressure class is also ensured in this eccentric construction. Due to this compact design the space requirement is reduced and the cost minimised when compared to standard fittings. The fittings to be offered must be manufactured from material in compliance with the PE100+ Association and according to DIN EN 12201 with respect to dimensions, tolerances and quality requirements. 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. The body of the fitting must be manufactured in the injection moulding process or alternatively, in the case of more complex structures, from a piece of homogeneous semi-finished material so as to ensure the required reinforcement and therefore high stability of the fitting. Semi-finished materials manufactured from wound rods or the subsequent application of other forms of reinforcing are not permitted. For the connections at the outlet and the two run pipes, pipe pieces of the same PE100 quality must be welded on according to the HE butt welding procedure ; inner beads of up to d 630 mm must be removed. The outlet must be of the level invert type to enable complete emptying. For the connection of accessories in the run line or at the outlet, PE100 flange connections of the same PE100 quality can be welded on according to the HE butt welding procedure; inner beads of up to d 630 mm must be removed.
