They can accommodate axial and lateral movements where anchoring of the pipe system is difficult or impractical due to structural or economic considerations. Pressure Balanced Expansion Joints do not transfer the internal pressure thrust on to the fix points, adjacent equipment, or structures. Fix points are usually not required, only guides can ensure the turning of thermal expansion into a controlled movement. Therefore, Pressure Balanced Expansion Joints can offer significant advantages, where pipe systems are connected with turbines, pumps, valves or other equipment, that are unable to withstand pressure thrust loads. Although Pressure Balanced Expansion Joints eliminate pressure thrust, it’s important to note that the existing load on the surrounding equipment is the total sum of the spring rates of both the flow bellows and balancing bellows.
