Every exhaust line expands when it heats up. If this movement is not absorbed, stress builds up at the adjacent components. Cracked welds and distorted nozzles are the usual result. An expansion joint absorbs the movement and also decouples vibrations between parts of the plant.
Besides expansion joints we supply knitted wire mesh and demisters for droplet separation.
