Filling in the pipe pit DN 80 - DN 00 BLS ® joints The pipe pit in the pavement should be filled in accordance with the „Merkblatt für das Verfüllen von Leitungsgräben“ [Directions for the filling of pipeline trenches] issued by the Road and Traffic Research Society (FGSV) of Cologne and with the „Zusätzliche Technische Vertragsbedingungen und Richtlinien for Erdarbeiten im Strassenbau“ [„Additional Technical Contractual Conditions for Earthmoving Work in Roadbuilding“] (ZTV E - StB 9 ). Pressure testing The documents that govern the execution of pressure tests on water pipelines are DIN EN 80 and DVGW Arbeitsblatt W 200-2. 11.2 Installation instructions for DN 80 to DN 500 BLS ® joints Construction of the DN 80 - DN 500 joint Cleaning The locks and those surfaces of the seating for the gasket, the retaining groove and the locking chamber which are indicated by arrows should be cleaned and any build-ups of paint should be removed. A scraper, e.g. a bent screwdriver, should be used to clean the retaining groove. Clean the inserting end. Retaining chamber Left lock Catch Right lock Welding bead TYTON ® gasket Socket Inserting end 10
Installation instructions Carefully wipe a thin layer of the lubricant supplied by the pipe manufacturer onto only the surfaces which are shown hatched. Assembling the joint Fitting the TYTON ® gasket Clean the TYTON ® gasket and pull it into a heart shape Insert the TYTON ® gasket into the socket in such a way that the external claw of hard rubber engages in the retaining groove in the socket Then press the loop in the gasket flat. If you have difficulty pressing the loop flat, pull out a second loop on the opposite side. These two small loops can then be pressed flat without any trouble. 10
