Decide according to the actual situation. Sleeve compensator adopts new type of sealing material flexible graphite ring, which has the characteristics of high strength, small friction coefficient, no aging, good effect, easy maintenance, etc. The sleeve compensator is mainly used for the auxiliary installation of linear pipeline. Sleeve compensator is suitable for hot water, steam, grease media, through the sliding sleeve to the outer sleeve of the sliding movement, to achieve the compensation of thermal expansion. With a small volume, the compensation volume is large. Widely used in urban heating, metallurgy, mining, power generation, petroleum, chemical, construction and other industries in the transport pipeline.
For some media instability and easy decomposition (such as the decomposition of some media will cause volume expansion caused by abnormal pressure rise) will cause sleeve compensator damage or leakage, measures should be taken to eliminate or limit the factors that cause the decomposition of unstable media. In the sleeve compensator selection, should consider the media instability and easy decomposition may cause changes in working conditions and select the sleeve compensator with automatic pressure relief device.
