Floating Flanged Expansion Joints
Floating flanged expansion joints are equipped with carbon steel or stainless steel flanges (EN, ASME, or as requested), absorbing mainly axial movement with the possibility of some lateral movement. The floating design keeps the flange out of direct contact with process media, since the bellows form the seal, and corrects flange misalignment during installation.
