Maintenance Free Filling Type Sleeve Compensator
Optimizing the advanced technology, we manufacture a qualitative range of Maintenance Free Filling Type Sleeve Compensators. It is mainly used for auxiliary equipment in straight pipeline. The applications of compensator are in hot water, steam, oil medium and so on, to achieve thermal expansion compensation between the sliding sleeve and outer sleeve by sliding movement, even can be applied in any difficult environment, in low temperature and pressure. Maintenance Free Filling Type Sleeve Compensator is characteristiced by inject special sealant material by check injection nozzle, the users can work more effectively to achieve more benefits. Don’t hesitate, please contact us learn more about compensator. We provide high quality and reasonable price for you.
Features
· Apply for medium engineering pressure ≤4.5MPa, temperature -190℃~630℃.
· Using the new style sealing material of flexible graphite,has the characteristics of high strength, small coefficient of friction (0.04~0.10), no aging, good effect, convenient maintenance and so on.
· With long life, fatigue life amount to pipeline. After special treated to sliding surface, it’s good corrosion resistance in salt water, saline solution and other environments, more higher than austenitic stainless steel 50 times. Meanwhile, after years of abrasion causes a sealing effect due to weakened , it can repair automatically without affecting use continued under the pressure of the spring tension.
· It is used without requirement of hloride ion content, especially suitable for medium or surrounding system of excessive chloride ions.
Sleeve compensator is divided into single-way and two-way types.Two-way structure is characterized by media inflowed from any side,sliding sleeve is always free to slide in both ends, realize two-way compensation, increase compensation amount.
· Buried sleeve-type compensator can be buried in the ground, may not be provided well repair when installation,low construction cost. Sleeve compensator is suitable for pipe laid by straight line, consists of inner sleeve, outer sleeve,check injection material combination, end sleeve, packing chamber, guide bearings and so on.
Structure Characteristic
· Relative sliding movement along the pipe axis direction of inner sleeve, absorbing pipe thermal expansion and contraction, to release thermal stress of the pipe.
· Inject special sealant material by check injection nozzle, to achieve balanced sliding seal in inner sleeves under sealing pressure.
· Rely on guide bearings to withstand pipeline lateral forces, to achieve relative movement of inner sleeves at high concentricity, prevent abrasions of plating sleeve, the sealing state is more reliable and durable during pipeline operation.
· Take a firm anti-extrusion design of extending into outer end of inner sleeve, make product more security.
