For more than a half century Hyspan has provided advanced flexible solutions with metal bellows expansion joints and hose assemblies in Scientific and Laboratory ultra-high vacuum (UHV) applications. Particle accelerators, magnetic fluids, thermo-acoustics, and other processes are supported for thermal motions, pump connections, installation clearances, system alignment, seismic allowances, and building settlement. 

Sizes range from 1” (25mm) through 20’ (6m). Complete metal bellows and hose assemblies with flanges, pipe, or tube ends are provided from 321, 304/304L, and 316/316L. Formed metal bellows are also available in Alloy 625, Alloy 718, and B265 Grade 2 Titanium. Flanges options include ConFlat® (CF), ISO, KF/QF, and others.
