A rotating compensator is a new type of compensator for thermal expansion in heating pipelines. The construction of the rotating compensator mainly consists of components such as an integral sealing base, sealing cover, flanges, antifriction alignment bearings, sealing materials, and a rotating cylinder. It requires two or more sets for installation on the heating pipeline to form a relative rotation that absorbs the thermal displacement of the pipeline, thereby reducing the pipeline stress.
Advantages of the rotary compensator:
(1) Large compensation volume, adaptable to natural terrain and pipeline strength; a single compensator group can compensate for 800 meters of pipeline.
(2) No blanking force generated by medium pressure, allowing for small fixed supports, particularly 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) The rotary compensator can be installed on steam and hot water buried pipelines, significantly saving investment and enhancing operational safety.
Rotary compensators are typically installed in sets of 150 to 500 meters on pipelines (determined by natural terrain), with over a dozen installation options, which can be determined based on 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 deflection. To reduce friction resistance during pipeline operation, rolling supports should be installed on sliding supports.
