In systems involving fluid transfer, unwanted movements can occur, which may stem from temperature changes due to the fluid or environment, vibrations from system components such as pumps and compressors, or external factors like wind, earthquakes, or structural settlement. To absorb these movements and prevent their transmission to existing equipment and piping, flexible joints are used. Metal Bellows Expansion joints are designed to withstand high temperatures and pressures while absorbing axial, lateral, and angular movements, considering appropriate configuration.

Routine welded and flanged Metal Bellows Expansion joints are produced in sizes ranging from ½ inch to 12 inches and with pressure capacities of 10 and 16 bar. They are primarily used in heating and air conditioning systems, exhaust outlets for combustion engines, heat exchangers, and in the wood and paper industries.
