The universal tied expansion joint is made up of two bellows joined together by a central pipe and a system of tie rods able to withstand the thrust produced by the internal pressure.
This model is used to absorb lateral movements in all planes. The tie rods are provided in sets of two or more, equally distributed around the circumference of the expansion joint. When the Expansion Joint is supplied with 2 tie rods at 180 degrees, the expansion joint is free to deflect angularly and laterally. With three or more tie rods, only lateral deflections are possible.
The amount of lateral deflection depends on the convolution number of the bellows on each side of the expansion joint. This amount can also be increased by changing the length of the central pipe. The tie rods are also effective to prevent possible torsion forces.
