Introduction: The sleeve compensator, called tubular expansion joint and pipeline expansion joint, is the compensation equipment of thermal fluid pipeline. It is used to absorb and compensate the axial thermal expansion displacement after the linear pipeline is auxiliary. It is directly installed in any pipeline conveying one-way or multi-directional fluid without corrosion

Sleeve Compensator Pipe type expansion joint and pipe Telescopic device It is a kind of compensator directly installed in any pipeline conveying non corrosive unidirectional or multi-directional fluid. Sleeve type compensator is widely used in urban heating, metallurgy, mining, power generation, petrochemical, construction and other industries in the pipeline.
The sleeve compensator is divided into unilateral type and bidirectional type compensation structure. The bidirectional type feature is that the sliding sleeves on both sides of the compensator always slide freely no matter where the medium is injected from the compensator, so as to achieve bidirectional compensation and increase the compensation amount.
The types of sleeve compensator are: elastic sleeve compensator, sleeve compound compensator, single sleeve compensator and double term thermal sleeve compensator.
Sleeve compensator is suitable for medium engineering, working pressure ≤ 2.5cpa, medium temperature - 40 ℃ ~ 600 ℃.
The sleeve compensator adopts new sealing material flexible graphite ring, which has the characteristics of high strength, small friction coefficient (0.04 ~ 0.10), no aging, good effect and convenient maintenance.
The service life of sleeve compensator is long and its fatigue life is equivalent to that of pipeline. After special treatment, the sliding surface has good corrosion resistance in salt water and salt solution, which is more than 50 times higher than that of austenitic stainless steel. In addition, when the sealing effect is weakened due to damage for many years, the flange can be tightened again to improve the sealing performance. The compensator can also loosen the bolts, take down the pressure ring, and then put one or two layers of sealing ring to clamp the pressure ring and apply again.
The sleeve compensator has no regulation on the chlorine ion composition, which is very suitable for the system with medium or surrounding environment exceeding the standard.
The directly buried sleeve type compensator can be directly buried in the ground, and there is no maintenance well during installation, so the project cost is low.
