1. Compact design and convenient installation.

2. Large compensation capacity. Low investment cost. The directly buried sleeve compensator adopts advanced injection pressure sealing technology to realize long-term reliable sealing and maintenance free. It can be directly buried underground without setting up an access shaft. The two-way sleeve compensator can compensate the thermal deformation of the pipes connected at both ends respectively, and the compensation capacity is greater.

3. The surface of the telescopic core tube adopts wear-resistant, high hard and smooth protective coating technology to improve the wear and corrosion resistance and greatly reduce the axial movement resistance of the telescopic core tube.

4. Flexible graphite composite sealing material with good resilience, high temperature resistance, corrosion resistance and aging resistance has sufficient sealing surface length to ensure reliable sealing of products.

5. The end of the core tube penetrating into the shell is provided with a firm anti falling structure to ensure that it will not be pulled apart when it is retracted to the position,.

6. A guide bearing bush is set between the inner and outer sleeves, which can bear the lateral force of the pipeline and improve the positioning, guiding performance and working stability of the inner sleeve.

7. In view of the special use environment of directly buried sleeve compensator installed underground, protective casing and protective baffle are added in the product structure design, which effectively reduces the entry of groundwater and sand into the sealing surface of the compensator, and is more conducive to thermal insulation and normal operation of the product.

8. High performance, long service life, up to more than 30 years.

9. It is easy to maintain and can be overhauled with temperature and pressure under normal working conditions.

It is mainly applicable to the auxiliary installation of linear pipeline in the official website. Its function is to compensate the axial expansion and displacement of thermal pipeline caused by thermal expansion and cold contraction.
