Square compensator, also known as rectangular compensator or L-shaped or Z-shaped compensator, is an important component used in pipeline system. It is mainly used to compensate pipeline deformation caused by thermal expansion and contraction, and absorb other unexpected displacements, such as earthquake, foundation settlement, etc. Its scope of action mainly includes the following aspects:
Thermal deformation compensation：
The square compensator can absorb the axial, transverse and angular thermal deformation generated by the pipeline when conveying high-temperature or low-temperature fluid, and prevent the pipeline from excessive stress due to thermal expansion and contraction, resulting in pipeline damage.
Structural deformation compensation：
The square compensator can absorb these structural deformations as the pipe passes through the expansion, seismic, or settlement joints of a building, preventing the pipe from being subjected to additional tensile or compressive forces.
Foundation settlement compensation：
A square compensator installed between the ground and the rising riser valve can solve the displacement caused by uneven settlement of the foundation and protect the pipeline from damage.
Equipment vibration absorption：
The square compensator can also absorb the vibration of mechanical equipment, reduce the influence of equipment vibration on the pipeline system, and improve the stability of the system.
Security and reliability enhancements：
By effectively compensating pipeline deformation, the square compensator can significantly reduce the risk of leakage and rupture of pipeline system due to thermal stress, and improve the safety and reliability of the whole system.
Extending pipeline life：
Reduces pipe fatigue caused by thermal stress, vibration, or structural deformation, thereby prolonging the service life of pipes and their connectors.
The design and installation of a square compensator needs to be determined according to the specific piping system and use conditions, ensuring that it can effectively perform the above functions. Square compensators are an integral component in industrial pipelines, heating systems, chemical plants, power stations, and other applications where pipeline compensation is required.
