New connecting system for water pipes

24.04.2003


Laying water mains has always been a time-consuming job. Each section must be laid, joints welded, the interior checked for heat damage, and any damage repaired. Then the whole thing has to be encased in concrete if the ground is uneven. Now EUREKA project DRIVE-LOCK is about to make the process quicker and cheaper.



The French and Swiss partners in the DRIVE-LOCK project have developed a new conical interlocking system that joins steel water pipes together quickly and combines the strength of a welded solution with the flexibility and speed of a conventional elastomer, or rubber, joint.

Christian Pallier, Project Manager of the French lead partner Hydrotechnique explains that DRIVE-LOCK saves 40–60 per cent of welding time. "The new joint has less coupling play, reducing the need for welding,” he says.


DRIVE LOCK also offers environmental benefits as a tighter, more secure joint means less water will leak away and be wasted.

The French partner Hydrotechnique designed the DRIVE-LOCK system and the Swiss partner, Romag, manufactured the prototype utilising its experience in the production of coated steel pipes.

DRIVE-LOCK offers the building site manager complete control over the joints required as a water main is being laid. Simply pushing together male and female DRIVE-LOCK cones may be sufficient in some circumstances. But a more secure joint can be added if necessary. For moderate strain, the joints can be welded in four places around the joint, locking it in place. Or the joint can be welded completely, making it strong enough to withstand strong pressures and uneven ground without requiring blocks of concrete.

The inner surface of the pipe is protected during welding by a synthetic resin coating, removing the need to inspect and repair the pipe. DRIVE-LOCK produces a hermetically-sealed inner joint which maintains water quality for longer.

Pallier found working in a EUREKA project required hard work but brought significant rewards. “EUREKA brought financial support and credibility to a new company, but it did require a lot of effort to follow through the project and its management, especially to coordinate the different partners.”

DRIVE-LOCK was completed on time, within budget, and in time for its launch at the French Pollutec 2002 show, ready to tap into the huge market for water mains. In Europe alone this represents 15–20,000 km of piping a year!

Im Focus: OLED microdisplays in data glasses for improved human-machine interaction

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

Im Focus: Artificial Intelligence Helps in the Discovery of New Materials

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

Im Focus: Complex hardmetal tools out of the 3D printer

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.

Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...

Im Focus: Launch of New Industry Working Group for Process Control in Laser Material Processing

At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.

In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...

Im Focus: New laser joining technologies at ‘K 2016’ trade fair

Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.

K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
