The direct buried corrugated compensator is mainly used for direct buried pipeline axial compensation, at the same time has super bending ability, so do not consider the influence of pipe subsidence, direct buried corrugated compensator in the shell and guide sleeve protection bellows free expansion compensation, other performance with ordinary corrugated compensator the same.
Direct buried compensator structure design is tight, stable operation, long service life suitable for the installation of pipeline buried laying, sealing work done well can be used for more than 30 years, do not need personnel maintenance.It can effectively compensate the axial displacement of the pipeline. Under the double-layer protection of the inner and outer sleeves, the elastic element of the directly buried corrugated compensator can avoid being affected by external factors and ensure the stability of the pipeline operation.
Performance characteristics of direct buried compensator expansion joints: It is mainly used to absorb the axial displacement caused by thermal expansion or contraction of directly buried pipelines along its axis direction. It has the characteristics of anti-soil pressure, self-direction, and can achieve the same life as the directly buried pipeline without maintenance and replacement. The product is designed to compensate for the limit structure, and the pipeline can be laid without a guide bracket. When it is used to transport corrosive media in pipelines or there is corrosive media in the environment, anti-corrosion coating can be applied to the inner wall or outer wall of the bellows.

Buried corrugated compensator application:
Buried corrugated compensator is the compensation device of hot fluid pipeline. direct buried compensator is mainly used for axial thermal expansion displacement absorption compensation after auxiliary installation of linear pipeline. It is a kind of compensator directly installed in any pipeline conveying unidirectional or multi-directional fluid without corrosion. Buried corrugated compensators are widely used in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries in the pipeline.
Directly buried corrugated compensator install：
1. In order to make the directly buried corrugated compensator play a compensating role, fixed supports should be set at both ends of the compensator to prevent the pipeline from being affected by the internal pressure thrust outward stretching.
2. one end of the compensator (refers to the one-way compensation of the buried compensator dead end) should be close to one end of the fixed support, with the compensator head compensation pipeline.
3. Set the distance between two fixed supports according to the compensation amount, and the compensation amount is generally not greater than the pipe diameter.
4. in the process of pressure test to the compensator shall not appear tensile phenomenon.
Directly buried 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.
