The rotary compensator is a new type of compensator for thermal expansion in heating pipelines. It is mainly composed of components such as an integral sealing base, sealing cover, reducers, antifriction locating bearings, sealing materials, and a rotating cylinder. Installation on the heating pipeline requires two or more sets to be assembled, 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, capable of being arranged based on natural terrain and pipeline strength; a large group of compensators can compensate for an 800m pipeline section.
(2) No blind flange force generated from medium pressure, the fixed bracket can be made very small, especially suitable for large diameter pipelines.
(3) Excellent sealing performance, no maintenance required for long-term operation.
(4) Significant cost savings on investment;
(5) Easy design and calculation.
(6) The rotating compensator can be installed on steam buried pipelines and hot water buried pipelines, significantly saving investment costs and enhancing operational safety.
Swivel compensators are typically installed in groups of 150-500m on pipelines (installation can be determined based on the natural terrain), and there are more than ten different installation options, which can be determined according to the pipeline 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 the frictional resistance of the pipeline operation, roller supports should be installed on the sliding supports.
