At the 8th Water Supply Networks Practice Day held in Gelsenkirchen, Germany, on 27 September 2018, developers, suppliers and users came together to listen to interesting expert talks on the subject of water and/or drinking water networks and to visit the associated trade exhibition.
Up to now, underground hydrants have mainly been coated with 2 coating systems, inside enamelled and outside epoxy. The seams of the two coating systems and the resulting defects were unavoidable. The new VAG standard is a complete epoxy powder coating (EPP). It eliminates seams between 2 coating systems and thus provides even better protection against corrosion. For standpost hydrants, the upper column outside is provided with an additional UV protection made of red-coloured polyester material on the outside.
