Expansion joints

Expansion joints can be used for practically any kind of movement: axial, lateral, angular and various combinations. Expansion joints are usually applied in the shell of fixed tube sheet exchangers and at the shell cover end of one-pass tube floating heads to absorb stresses due to differential thermal expansion.
