Hinged Expansion Joint

Hinged Expansion Jointed are usually used in a set of two or three, to absorb lateral deflection in one or more direction in a single plane piping system. The Joint in such system is restricted to pure angular rotation by its hinges. Each pair of hinged Expansion Joints, separated by a segment of piping, will act in unison to absorb lateral deflection in much the same manner as a swing or universal Expansion Joint in a single plane application. For a given angular rotation of the individual Expansion Joints, the amount of lateral deflection that a pair of hinged Expansion Joints can absorb is directly proportional to the distance between their hinge pins.
