Angular expansion joints
Angular expansion joints are suited for the compensation of both long pipe sections of district heating systems as well as short boiler and turbine room pipelines in one or more planes.
For installations with very limited space one should also check the possibility of the installation of tied universal or pressure balanced expansion joints.
Contrary to axial and universal expansion joints that are suited to compensate for movements independently, angular expansion joints are only elements of an expansion system.
Angular expansion joints are usually installed with 50% pre-stressing. This is accomplished by pre-stressing the entire expansion system after its completion. The pre-stressing amount can be determined taking into account the installation temperature.
What are the primary applications of Angular expansion joints in piping systems?
Angular expansion joints are primarily used for the compensation of thermal expansion and contraction in both long pipe sections of district heating systems and short pipelines in boiler and turbine rooms. They are specifically designed to manage movements occurring in one or more planes, ensuring the integrity and functionality of the piping systems under varying thermal conditions.
How do Angular expansion joints differ from Gimbal expansion joints?
While both Angular expansion joints and Gimbal expansion joints serve the purpose of accommodating angular movements, Gimbal joints are specifically engineered to allow angular movement in any plane through the use of two pairs of hinges. In contrast, Angular expansion joints are more versatile and can accommodate more complex movement patterns, making them suitable for installations with limited space.
What should be considered when selecting Angular expansion joints for a specific installation?
When selecting Angular expansion joints, it is crucial to consider factors such as the type of movement expected (angular, lateral, or axial), the operating temperature and pressure conditions, as well as the available installation space. For applications in constrained environments, options like Double gimbal expansion joints with welding ends may provide enhanced flexibility and adaptability.
