Metal expansion joints are flexible components designed to absorb thermal expansion, vibration and movement in piping systems. Depending on the piping layout and movement requirements, different configurations may be used, including axial, hinged, gimbal, pressure balanced and externally pressurized expansion joints.
Selection should consider operating pressure, design temperature, medium, nominal diameter, movement requirements, installation length, material and applicable standards. In power generation, petrochemical, district heating and other industrial piping systems, a properly selected expansion joint can help reduce stress on piping and connected equipment.
For a more accurate recommendation, customers are encouraged to provide drawings, operating conditions and required movement data when requesting a quotation.
