Expansion joints for innovative future technologies

120-Referenz-Nuklear-Fusion
These single-ply expansion joints DN 200 are designed, manufactured and tested for a research institute, which is a spin-off of MIT's Plasma Science and Fusion Center. To meet the conditions in the high field tokamak, a helium leakage rate of <1 x 10-9 mbar*l/sec is needed.

Design pressure: -1 to 0.2 bar g
Design temperature: -45 °C to 10 °C
Movement: axial -15mm, angular -4°
Spring rate: axial Cx 84 N/mm, angular 9 Nm/degree
Test: Helium Leakage Test
