The rotating compensator is a new type of compensator for thermal expansion in thermal pipelines. It is mainly composed of components such as a complete sealing base, sealing cover, reducing-end, antifriction locating bearing, sealing material, and rotating cylinder. To be installed on a thermal pipeline, it requires two or more sets assembled together, forming a relative rotation to absorb the pipeline's thermal displacement, thereby reducing the pipeline stress.
Advantages of the rotary compensator:
(1) Large compensation volume, can be arranged according to natural terrain and pipeline strength; a set of large compensator can compensate for 800 meters of pipeline.
(2) No blanketing force is generated due to medium pressure, allowing for very small fixed supports, particularly suitable for large diameter pipes.
(3) Superior sealing performance, requiring no maintenance for long-term operation.
(4) Significant investment savings.
(5) Easy design calculations
(6) Rotating compensators can be installed on steam buried pipelines 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 (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 friction resistance during pipeline operation, rolling supports should be installed on sliding supports.
