This expansion joint is a customized solution for an international research institute and the bellows will be installed in a nuclear fusion reactor.

kompaflex designed and manufactured these DN 150/200 double bellows with single-ply design and suitable interspace between the bellows for pumping and leak monitoring according to EN 14917.

We carried out various in-house tests, such as helium leakage test <1×10^-9mbar*l/s, baking test at 180 °C, spring rate test and LPT.
