A rotating compensator is a new type of compensator for thermal expansion in thermal pipelines. The construction of a rotating compensator mainly consists of components such as an integral sealing base, sealing cover, reducers, friction-reducing centering bearings, sealing materials, and a rotating cylinder, which need to be assembled in two or more sets when installed on a thermal pipeline to form relative rotation and absorb the thermal displacement of the pipeline, thereby reducing the stress on the pipeline.
Advantages of the Rotating Compensator:
(1) Large compensation volume, adaptable to natural terrain and pipeline strength; a group of compensators can compensate for 800 meters of pipeline.
(2) No blind flange force generated by medium pressure, the fixed bracket can be made very small, especially suitable for large diameter pipes.
(3) Excellent sealing performance, requires no maintenance for long-term operation.
(4) Significant investment savings.
(5) Easy design and calculation.
(6) Swivel compensators can be installed on steam buried pipelines and hot water buried pipelines, significantly reducing investment costs and enhancing operational safety.
Rotary compensators are typically installed in sets of 150-500m on pipelines (installation can be determined based on natural terrain), with over a dozen installation options, which can be determined according to the pipeline's direction. After using this type of compensator, the spacing between fixed supports is increased, and guide supports should be appropriately added to avoid pipeline bending. To reduce frictional resistance during pipeline operation, rolling supports should be installed on sliding supports.
