PTFE expansion joints for high pressures are usually thought for absorbing vibrations and expansions, a quite common situation on the pipes because of differences of temperatures, pressures or external movements and the weight of the pipes itself. Where the values of forces and movements overtake the acceptable values it’s necessary to use the expansion joints that allows to absorb expansions and vibrations in excess.
