Flexible elements for power Generation

For conventional power plants, our standard product range includes flexible pipeline elements and our pipe support range. In the maintenance field with the rapidly available warehouse range.

Our expansion joints, valve bellows and flexible metal hoses are used in research plants such as CERN, DESY, ITER or also the Wendelstein fusion stellarator. And in conventional nuclear plants.

More than 40 inspections during the production process, a multitude of tests before, during and after production, checks during the processes by customers and certification companies ensure production is monitored to the highest degree possible. Starting with material tests and ranging as far as special film packaging for the flexible pipeline elements.

Depending on their use, cogeneration units are operated as combustion engines, gas engines, gas turbines or fuel cells. Based on the principle of power-heat coupling, they are used where power or heat are needed.
As with large engines, e.g. for ships, we ensure long-term functional safety here in liquid closed loops, exhaust gas sytems before and after the turbo charger or in charged air pipes.

In parabolic trough and fresnel power plants, solar rays are concentrated in a receiving tube via a mirror. This consists of a coated steel tube that transports a heat-bearing medium and a vacuum-insulated glass tube. Metal bellows are needed at each end of a receiver section to absorb heat expansions and maintain the vacuum between the tubes.

Mirrors and receivers in parabolic trough power plants track the sun, the receivers expanding as they are heated. High pressure metal hoses are used as a flexible connection to the fixed tubing of a power plant.

In modern wind power systems, flexible metallic pipeline elements are used to compensate for vibrations, torsional movements and to transport media.

For example, flexible metal hoses in hydraulic oil and coolant circuits, or as heat exchangers, to cool power generators.
