The Fachgemeinschaft Guss-Rohrsysteme (FGR) e.V. is a technical and scientific association whose membership comprises European companies producing pipes, fittings and valves made of ductile iron.  The association also operates under the English-language name European Association for Ductile Iron Pipe Systems ∙ EADIPS. Through its public relations work, the association endeavours to ensure that there is an idea that is firmly rooted in the minds of those who make professional use of these products or who take a specialist interest in them, namely that all the tasks connected with the transportation of drinking water, waste water and sewage can be performed easily, safely, reliably and economically with the ductile iron pipe system (pipes, fittings and valves).


Large-dimension interim pipeline with cast iron systems

Positive locking and flexible thrust-resistant systems have extended the range of application of ductile cast iron systems and shown that they can withstand all loads produced by internal and external forces. In the construction and during the operation of pipelines with restrained joints in tunnels and under bridges, when used with the application of trenchless installation techniques …
