flange pressure plate oil filled directly buried sleeve compensator
Sleeve compensator, called tubular expansion joint, is a
compensation device for hot fluid pipeline, which is mainly
composed of sleeve (core pipe), shell, sealing material, etc It is
used to compensate the axial expansion and contraction of the
pipeline and axial rotation at any angle It has the characteristics
of small volume and large compensation. It is suitable for hot
water, steam and grease media. Through the sliding movement of the
sliding sleeve to the outer sleeve, it can achieve the compensation
of thermal expansion.
Performance of oil filled directly buried sleeve compensator
1. The sleeve expansion joint is designed with an anti breaking
device, which can ensure that it will not be opened when it expands
to a certain position, so as to improve the safety and stability of
the operation of the whole pipe network.
2. Sleeve expansion joint is applicable to medium engineering
pressure ≤ 2.5MPa and medium temperature - 40 ℃ ~ 600 ℃.
3. The sleeve expansion joint adopts a new sealing material
flexible graphite ring, which has the characteristics of high
strength, low friction coefficient (0.04 ~ 0.10), no aging, good
effect and convenient maintenance.
4. The service life of sleeve expansion joint is long, and the
fatigue life is equivalent to that of pipeline. After special
treatment, the sliding surface has good corrosion resistance in
brine, salt solution and other environments, which is more than 50
times higher than that of austenitic stainless steel.
5. The sleeve expansion joint has no requirements for chloride ion
content and is applicable to the system in which the chloride ion
in the medium or the surrounding environment exceeds the standard.
6. The directly buried sleeve expansion energy-saving is directly
buried underground. The maintenance well can not be set during
installation, and the project cost is low.

Oil filled directly buried sleeve compensator advantage
1. The single way sleeve compensator has a long service life, and
its fatigue life is equivalent to that of the 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.
2. The maintenance free direct buried single way sleeve compensator
has no requirement for chloride ion content, and is especially
suitable for the system with excessive chloride ion content in
medium or surrounding environment.
3. The maintenance free direct buried single way sleeve compensator
can be divided into one-way and two-way compensation structures.
The two-way compensation structure is characterized by that the
sliding sleeves at both ends of the compensator always slide freely
no matter where the medium flows from, so as to achieve two-way
compensation and increase the compensation amount.
Oil filled directly buried sleeve compensator application
Sleeve compensator is called tubular expansion joint and pipeline
expansion joint, which is the compensation device of hot fluid
pipeline, mainly used for the auxiliary equipment of linear
pipeline. It is suitable for hot water, steam, grease and other
media. Through the sliding movement of the sliding sleeve, the
thermal expansion compensation can be achieved.
