Heinrich Witzenmann invented the flexible metal tube in 1885. This was the foundation of the flexible metal tube and expansion joint industry. Nowadays, flexible metal tubes of the "HYDRA®" brand are used as flexible line elements in virtually all markets. They absorb motions and vibrations or compensate for mounting tolerances.
Their universal properties render flexible metal tubes very versatile. In the temperature range from -270°C to approx. 600°C, from vacuum to 380 bar. Moreover, the available range of nominal diameters from 1.8 mm to 300 mm opens up a wide range of applications.
Flexible metal tubes comprise wound tubes and corrugated hoses. While the former are characterised by their high mechanical strength, the latter excel based on their tightness and high compressive strength when used as braided conduit
in regenerative energy generation, e.g. as media lines in solar power stations or in solar thermal applications, protective hoses in wind power stations, off-shore …
