The Universal Bellows With Pipe Ends Expansion Joint (articulated double expansion joint-containing two bellows joined by a common connector for the purpose of absorbing any combination of the three basic movements : Axial, Lateral and Angular) usually furnished with control rods to distribute the movement between the two bellows of the expansion joint and to stabilize the common connector. Overall control rods govern the movement of the center pipe section and equally divide motion between the bellows elements. This configuration is used primarily for lateral deflection but can accommodate axial movement as well. Another application for this type of expansion joint utilizes overall tie rods which fix the overall length of the expansion joint and contain full pressure thrust (only lateral deflection is accommodated).
