Directly buried note filling type sleeve compensator is introduced
Buried note filling sleeve type compensator and sleeve compensator structure are similar, for application in the low temperature water injection filling sleeve type compensator, as long as the set of high finish internal sliding surface to protect it, it can be used in the underground buried, under normal operating conditions (excluding influence factors such as earthquake, subsidence) can life with pipeline, there is no need to maintain. For steam pipelines buried underground, it is recommended to use composite filling type sleeve compensator is build by laying bricks or stones repair injection Wells.
Directly buried note filling sleeve type compensator are suitable for straight line laying pipeline, the inner sleeve, coat, check on the material composition, end cover, packing chamber and guide bearing, etc.

Directly buried note filling type and the structure characteristics of sleeve compensator
(1) through the inner sleeve along the pipe axis direction of the relative sliding motion, absorb piping hot elongation of cold and hot shorten, to release the pipeline thermal stress.
(2) special sealants through check injection nozzle injection, making the set of the balance between a sliding seal under pressure.
(3) rely on the guide bearing pipes under lateral force, implementation, a set of relative motion spot high alignment, prevent scratch plating inner sleeve, make the pipe under the running condition of seal is more reliable and durable.
Inner sleeve (4) into the coat end take strong emergence design, make the product more security.
