Sleeve compensator can be divided into unidirectional type and bidirectional type. The bidirectional type is characterized by that the sliding sleeve at both ends of the compensator always slides freely regardless of which end of the compensator the medium flows in, so as to achieve bidirectional compensation and increase the compensation amount. Sleeve compensator is suitable for medium engineering pressure ≤ 2.5mpa, medium temperature -40℃~600℃.

 

The sleeve type compensator USES the new sealing material flexible graphite ring, it has the strength big, the friction coefficient is small (0.04~0.10), does not age, the effect is good, the maintenance is convenient and so on. Sleeve compensator is mainly used for auxiliary equipment of straight pipeline. Telescopic compensator is suitable for hot water, steam and grease media. It can compensate thermal expansion by sliding movement of the sleeve. It has the characteristics of small volume and large compensation amount. Widely used in urban heating, metallurgy, mining, power generation, petroleum, chemical, construction and other industries in the pipeline.

 

Sleeve compensator has a long service life, and its fatigue life is equal to that of pipeline. After special treatment, the sliding surface has good corrosion resistance under the environment of brine and salt solution, and is 50 times higher than austenitic stainless steel. At the same time, many years later due to wear and tear the sealing effect is weakened, can tighten the flange again, enhance the sealing performance, also can loosen the bolt, take the lower pressure ring, and then into a layer or two layers of sealing ring, pressure pressure ring, continue to use. Sleeve compensator has no requirement for chloride ion content, especially suitable for the system where medium or ambient chloride ion exceeds standard.

 

Technical specification of sleeve compensator

 

Nominal diameter design pressure working temperature working medium

 

Dn80-1200mm ≤4.0Mpa≤450℃ hot water, high temperature hot water, water vapor, non-corrosive gaseous or liquid medium

 

Sleeve compensator, also known as tubular expansion joint and pipe expansion device, is a compensation device for thermal fluid pipelines, mainly used as auxiliary equipment for linear pipelines. Suitable for hot water, steam, grease media, through sliding sleeve external sleeve sliding movement, to achieve thermal expansion compensation.

 

Conclusion:

 

Sleeve compensator: can also withstand higher pressure and temperature, large compensation, easy installation. Disadvantages: easy to leak, frequent maintenance, large thrust. Can not be used for high fluid purity requirements.
