The Toroidal Expansion Joints are mainly design for high-pressure application where needs small amounts of movement. The majority of these joints are designed for Heat Exchanger in accordance with ASME Sec VIII,Div-1, Appendix 26 and also as per EJMA for other application. The natural stability of a circle under internal pressure is allows the thin walled toroid element to withstand pressures that a apparently more stable multy ply, reinforced bellows could not. The advantage of this design are its easy to manufacture with low material cost of bellows element and the stability of the expansion joint even at pressures well beyond the design conditions. The only drawback is the small amount of movement the joints can absorb, which when dealing with heat exchanger designs, is all that is required.
