A Universal Expansion joint is an assembly containing two bellows connected by a centre pipe and equipped with tie rods. Universal Expansion joints are mainly used to absorb any combination of the three basic movements in the piping system. (Axial, Lateral, Angular).
Ball-and-socket joints are classified functionally as multiaxial joints because they can move bones along several axes. The muscles that surround the joints permit the humerus and femur to move away from the bodyâs midline (abduction), toward the bodyâs midline (adduction), forward (flexion), and backwards (extension).
