Fixed Flanged Expansion Joints

Fixed flanged expansion joints are equipped with welded carbon steel or stainless steel flanges (EN, ASME, or as requested), absorbing mainly axial movement with some lateral capacity. Unlike floating flanged types, fixed flanges can operate at higher pressures, and a double bellows configuration is available for greater lateral movement.
