Metal Expansion Joint

Heat Exchanger Expansion Joint

The expansion joints used as an integral part of heat exchanger are designed to provide flexibility for thermal expansion and also to function as a pressure containing element. The bellows consist of formed flexible elements with multiple or single convolutions and will be of the unreinforced or reinforced type depending upon operating pressure. Bellows are fabricated of austenitic stainless steel, Hastelloy, Inconel etc.

Design of this type of expansion joint complies with the standards of both ASME Section Ⅷ and EJMA latest edition.
