Ocelflex - Single Axial Expansion Joint

Even though a single circular expansion joint can absorb all the three movements, it is more capable of absorbing movement in the axial directions and less in the lateral or angular directions. This simple circular expansion joint, also known as Single Axial Expansion Joint, is used in applications which require minor movements, such as vibrations or thermal fluctuations, applications such as in pumps and compressors, boilers, engines and pressure vessels. The metal expansion joint cannot resist any deflections with force except the resistance of the metal expansion bellows, which is a function of the spring rate times the deflection amount.
