Witzenmann's flexible metallic elements and pipe brackets are used in many power generation plants. Our products ensure security and optimal operation not only in conventional power plants (coal, gas, oil), in nuclear power plants, in stationary large engines but also increasingly in wind and solar power plants (CSP).
Utmost reliability, comprehensive documentation
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 or when power plants are being dismantled.

Iter Vacuum Handbook
From 1.4571 via magnifier, mu-metal to high-alloy stainless steels - with our broad experience and certified welding approvals, we have a wide range of possibilities for using the right material in each case along with appropriate processes.
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 of the flexible pipeline elements.
Every individual product process must be documented and remain viewable for 30 years. This quickly reaches 5000 pages. A measure to secure the overall system later.
Alongside the process technology, documentation is one of the biggest challenges in nuclear engineering.
In the nuclear field, especially, it is important to be able to model a matching product range. This reduces safety risks and enhances operating efficiency.
