The rotary compensator is a new type of compensator for thermal expansion in thermal pipelines. The construction of the rotary compensator mainly consists of components such as a full-sealed base, sealing cover, elbows, friction-reducing centering bearings, sealing materials, and a rotating cylinder. It requires two or more sets to be assembled on the thermal pipeline, forming a relative rotation to absorb the thermal displacement of the pipeline, thereby reducing the pipeline stress.
Advantages of the rotary compensator:
(1) Large compensation capacity, adaptable to natural terrain and pipeline strength, with a single compensator group capable of compensating for 800 meters of pipeline.
(2) No blind flange force generated by medium pressure, allowing the fixed bracket to be made very small, especially suitable for large diameter pipes.
(3) Excellent sealing performance, requires no maintenance for long-term operation.
(4) Substantial 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.
Swivel compensators are typically installed in sets of 150-500m on pipelines (installation can be determined based on natural terrain), and there are over ten different installation methods that can be chosen based on the pipeline 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.
