The use of a compensator involves multiple steps from preparation before installation to final commissioning. Here are the general steps and considerations for using compensators, especially corrugated and spherical compensators:
Use of Ripple Compensator
Preparation before installation
Check Specifications: Verify that the model, specification and piping configuration of the compensator meet the design requirements.
Appearance inspection: Check the compensator for damage, scratches or foreign objects and ensure the interior is clean.
Ancillary facilities: Check that the necessary auxiliary locators and fasteners are equipped.
Installation process
Avoid deformation: It is strictly prohibited to use the deformation of the corrugated compensator to adjust the installation error of the pipeline.
Direction confirmationFor the inner sleeve compensator, ensure that the direction of the inner sleeve is consistent with the direction of the medium flow; The hinge rotation plane of the hinge type compensator shall be consistent with the displacement rotation plane.
Temporary support: During installation, temporary support devices are used to prevent the compensator from bearing additional weight or stress.
Welding and Protection: Protect the corrugated compensator from slag splashes and mechanical damage during welding operations.
Post-installation debugging
Removing auxiliary parts: Remove the auxiliary positioning piece used during installation.
Limit device: Adjust the limit device according to the design requirements to ensure that the compensator can fully compensate under the working conditions.
Stress testing: Perform hydraulic or pneumatic tests to ensure the tightness of the compensator and piping system.
Use of spherical compensators
Preparation before installation
Dimensional inspection: Check that the cosmetic dimensions of the spherical compensator meet the requirements.
Pre-stretched or pre-compressed: Pre-stretch or pre-compress the spherical compensator as needed.
Installation process
Weld position: If the spherical compensator has a weld, the weld end should be installed on the horizontal pipe where the medium flows, and the weld should be located above the vertical pipe.
Coaxiality: Ensure that the spherical compensator is coaxial with the pipeline to avoid deviation.
Temporary support: Use temporary bracing during installation until the ductwork is fully secured.
Debugging after installation
Check for uneven settlement: After removing temporary supports, check for uneven settlement.
Guide device: Install a guide on the pipe rack near the spherical compensator to control the movement of the pipe.
Considerations in Use
maintenance: Check the condition of the compensator regularly, clean up foreign objects, and ensure the flexibility of moving parts.
record: Record the operating status and maintenance history of the compensator to facilitate failure analysis and predictive maintenance.
The above steps and precautions are all to ensure that the compensator can normally play its role of absorbing the displacement of the pipeline system, at the same time, prolong its service life and ensure the safe operation of the pipeline system.
