7,5 km Drainage Pipeline in Slovakia

For bridge drainage it was decided to utilize HOBAS CC-GRP BridgeLine Systems. High corrosion resistance, excellent hydraulic properties, a quick assembly under also challenging conditions, absolute leak tightness, angular deflection in the couplings, a long lifetime and resistance against UV light were the main points that convinced the client. Along with these advantages, several successful bridge projects in Slovakia and abroad that have been and are currently carried out with HOBAS Pipes facilitated the decision. The CC-GRP Drainage Pipes are partly fixed on hangers and partly run inside the bridge itself. At curved sections with smaller radii the standard 6 m long pipes were cut into two to fully exploit the angular deflection in a higher number of joints and to ultimately achieve sharper bends. This way the pipelines were perfectly adapted to their route along the bridge. Made to measure HOBAS CC-GRP Fittings rounded the employed product range and played an important role in fulfilling the project’s requirements.
