The rotary compensator is a new type of compensator for thermal expansion in thermal pipelines. Its structure mainly consists of components such as an integral sealing base, sealing cover, reducing ends, friction-reducing alignment bearings, sealing materials, and a rotating cylinder. Installation on a thermal pipeline requires two or more sets to be assembled, forming a relative rotation to absorb the thermal displacement of the pipeline, thereby reducing pipeline stress.
Advantages of the rotary compensator:
(1) Large compensation capacity, adaptable to natural terrain and pipeline strength; a group of compensators can compensate for 800m of pipeline.
(2) No blind flange force generated by medium pressure, the fixed bracket can be made very small, particularly suitable for large diameter pipelines.
(3) Excellent sealing performance, requires no maintenance for long-term operation.
(4) Significant investment savings
(5) Easy design calculations
(6) Swivel compensators can be installed on steam 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 (the installation can be determined based on natural terrain), with more than ten different 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. To avoid pipeline bending, it is necessary to appropriately increase guide supports. To reduce frictional resistance during pipeline operation, rolling supports should be installed on sliding supports.
