Compensator is an important component used in pipeline systems, designed to absorb displacement of pipes due to temperature changes, mechanical vibrations, foundation settlement or installation errors, to prevent damage caused by excessive stress on pipes. Here are some of the main types of compensators and their respective roles:
Species
bellows compensator：
Axial type: Thermal expansion and contraction in the axial direction of the absorption pipe.
Transverse type: suction The lateral displacement of the collection pipe.
Angular type: Absorb the angular (rotational) displacement of the pipe.
Compound type: It can simultaneously absorb axial, lateral and angular displacements.
sleeve compensator: The axial displacement is absorbed by the relative sliding of the inner and outer tubes.
Square compensator(U-shaped or L-shaped elbow): Uses the bending of the pipe itself to absorb thermal expansion and contraction.
Spherical compensator: The displacement of the pipe in multiple directions is absorbed by the rotation of the sphere.
Rotary compensator: Use the force couple principle to absorb axial displacement without external thrust.
Direct buried compensator: Designed for direct buried pipelines to withstand soil pressure and groundwater corrosion.
Tie rod transverse corrugation compensator: Used to limit the lateral displacement of bellows, suitable for axial compensation.
Pressure balance compensator: Designed to balance the pressure differential between inside and outside the pipe.
Non-metallic compensator: Use non-metallic materials such as rubber, silicone or fiber fabric, suitable for gas pipelines.
effect
Compensate for thermal expansion and contraction: Changes in the length of the absorption pipe due to changes in temperature.
Reduce vibration: Absorb mechanical vibration and mitigate the impact of equipment on pipelines.
Adaptive displacement: Compensate for axial, transverse and angular displacement of the pipe.
Stress reduction: Reduces stress on pipes and connections such as valves and pumps.
Improve security: Protects the piping system from excessive stress and deformation and extends the service life.
Noise reduction: Reduces noise and vibration in plumbing systems.
Choosing the correct compensator type requires consideration of the operating conditions of the pipe, including the type of media, temperature, pressure, direction of displacement, and expected amount of displacement. When designing pipeline system, reasonable selection of compensator is very important to ensure the safe and stable operation of the system.
