Aug 12, 2016 Article Dr.-Ing. Jürgen Rammelsberg The “50th” anniversary issue of the EADIPS®/ FGR® annual journal has been an occasion to look back over the history of 500 years of drinking water transport and distribution. This area of life is inseparably linked to the traditional material of “cast iron”: it has put its stamp on the development of drinking water supply for half a millennium but, with a constant influx of improvements, optimisations and innovations over this timespan, it has nevertheless remained ever young. The cast iron pipe industry, in collaboration with its users, has always managed to keep abreast of the latest state of the art with a modern and sustainable piping system comprising pipes, fittings and valves.

Jun 27, 2017 Article Ing. Christian Auer The use of ductile iron pipe systems for penstock pipelines is constantly increasing with the promotion of renewable energy sources. In this area of application the mechanical and technological requirements placed on pipe materials as well as the need for security are considerably higher than for pipes used for the distribution of drinking water. Therefore it is imperative that material modifications are developed to meet these increased demands. This report describes the safety concept (the “leak-before-break criterion), the technical material modifications and investigations necessary for practical implementation which will result in better utilisation of ductile cast iron as a material in high-pressure applications and the particular requirements for both crew and piping systems when laying turbine pipelines in alpine environments. All in all a basket of technical goodies!

Mar 20, 2018 Article Uwe Hoffmann A dilapidated steel pipeline frequently in need of repair was located in an ecologically sensitive area which has meanwhile been reclassified as an FFH site. In order to avoid further disruptions due to repair work, the old pipeline needed to be replaced without disturbing the biotope and without going in with heavy equipment. Nowadays tasks of this kind are solved very elegantly with ductile iron pipes which are pulled in by means of the single pipe assembly HDD “nonimpact” process.

Jul 07, 2022 Article TEPPFA The pipe landscape all over the world is changing. Pipe materials have evolved from grey cast iron and lead into today’s ductile iron, steel and plastics (PE and PVC). Yet it is plastic pipes that have produced the most exciting developments, and possible solutions to longer term issues like leakage, environmental impact and whole-life pipe performance.

Jul 24, 2017 Article Dr.-Ing. André Clauß Simply for geological and topographical reasons alone, the renewal of a drinking water transport pipeline in the densely wooded region of the Western Ore Mountains is no straightforward undertaking. Thanks to modern piping systems with their highly developed structural design methods, joint technologies and corrosion protection techniques, projects of this kind can be handled without problem. In the case illustrated here, the planning engineers were confronted with a fairly unusual additional challenge in the form of the soft, unbuffered water in the reservoir which, in conjunction with the cement mortar lining of the pipe, can be subject to an inadmissible increase in its pH value in stagnation phases. By using a proven method, endorsed in the DVGW regulations, of applying carbon dioxide gas under pressure in individual sections of the pipeline before acceptance and commissioning it was possible to ensure that the drinking water in the “Auer Ring” always meets the directives of drinking water legislation.

Jul 19, 2017 Article Dr.-Ing. Dietmar Beckmann Many large interceptor sewers, predominantly installed under public roads, have been in use for over 100 years. They are made of brickwork or compressed concrete and often show serious damage, so that it would seem that long-term stability can no longer be guaranteed. As an alternative to replacing large profiles, various renovation procedures offer significant advantages with respect to investment costs, environmental protection and urban pollution. Depending on the procedure, it may well be possible to extend the service life, in order to match that of a replacement. However, beforehand, an in-depth study of the current stability and residual load capacity of the existing sewer is required, along with needs-based selection and dimensioning of the rehabilitation procedure. The new standard DWA-A 143-2 serves as a good basis for the necessary static calculations.
