TUEB - Tied Universal Expansion Bellows

Aflex Tied Universal Expansion Bellows are able to absorb large amounts of lateral deflection in both single plane and multi-plane piping configurations. TUEB assemblies are suitable in low-medium pressure ranges, as the tie rods will restrain the pressure thrust from the bellows. This prevents the pressure thrust force being transmitted onto the piping, anchors, and adjacent equipment, which can cause significant damage or even failure of the pipeline.
Tied Universal Expansion Bellows
TUEB are used in 90° offset legs of pipelines to accommodate the thermal expansion of the adjacent long straight sections of pipe, as shown in the diagram on the right. Wherever feasible, the Aflex TUEB should be designed to fill as much of the offset leg as possible, to ensure any expansion of that leg itself is absorbed within the tie rods.
