The selection of the installation location of the sleeve compensator is crucial, which directly affects the safety and efficiency of the pipeline system. Here are some basic principles and considerations regarding where the sleeve compensator is installed:
Near fixed bracket：
The one-way sleeve compensator shall be installed on a straight pipe near the fixed bracket, close to the position of the fixed bracket. This helps control the displacement of the pipe and reduces the lateral thrust of the pipe.
The two-way sleeve compensator should be installed at the midpoint of the pipe between the two fixed brackets, so that the thermal expansion and contraction stress of the pipe can be more evenly dispersed.
Avoid interfering parts：
Avoid installing compensators near pipe elbows, valves, pumps and other accessories, as there may already be stress concentrations in the pipes in these places, and adding compensators may further increase local stresses.
Perpendicular to the axis：
The compensator should be mounted perpendicular to the pipe axis to ensure that it can expand and contract freely when the pipe expands and contracts thermally without the additional stress of twisting or bending.
spacing：
Typically, the sleeve compensator installation intervals depend on the thermal expansion coefficient of the pipe and the operating temperature. It is generally recommended to install a compensator every 15-20 meters, but this is not a hard rule and should be determined according to engineering design and calculation.
Coaxiality：
Good coaxiality should be maintained between the compensator and the pipe to reduce unnecessary friction and wear.
Direction of media flow：
For compensators with media flow requirements, ensure that the media flows in from the core tube end and out from the outer sleeve end to ensure the normal operation of the compensator.
Inspection and maintenance：
The convenience of inspection and maintenance of the compensator should be considered to ensure that the installation position is convenient for future inspection and necessary adjustment of the compensator.
Pre-stretching：
Depending on the specific working conditions, it is sometimes necessary to pre-stretch the compensator during installation to offset part of the thermal expansion and reduce the compensator stroke during operation.
Secondary fixation bracket：
In some cases, particularly on long-distance pipes, it may be desirable to provide a secondary fixation bracket near the compensator to limit the lateral displacement of the pipe.
When designing the pipeline system, the engineer will determine the best installation position of the compensator according to the above principles, combined with the thermal calculation and mechanical analysis of the specific project. In addition, it is necessary to refer to relevant industry standards and specifications, such as the ASME B31 series standards, to ensure the safety and compliance of the installation solution.
