Directly buried sleeve compensator
Maintenance free direct buried single way sleeve compensator is one
of the compensators. It is widely used in many industries because
of its advantages of long service life, good corrosion resistance,
no requirement for chloride ion content, bidirectional compensation
and increasing compensation amount.
Performance of directly buried sleeve compensator
The expansion capacity and pressure resistance of the directly
buried one-way sleeve compensator are as follows:
Sleeve compensator plays an important role in many industrial
fields. Different types of compensators have different application
ranges and methods, and the application of compensator joints in
heating pipelines. In order to prevent pipe deformation and damage
caused by thermal elongation or temperature stress during heating,
compensator shall be set on the pipe to compensate for the thermal
elongation of the pipe, so as to reduce the stress on the pipe wall
and the effect on the valve or support structure

Directly buried sleeve compensator advantage
1. The service life of the compensator is long, and the fatigue
life is equivalent to that of the pipeline. After special
treatment, the sliding surface has good corrosion resistance in
brine and salt solution, and its corrosion resistance is more than
50 times that of austenitic stainless steel.
2. The compensator has no requirements for chloride ion content,
and is especially suitable for systems with high chloride ion
content in the medium or surrounding environment.
3. The sleeve compensator can be divided into unidirectional and
bidirectional compensation structures. The feature of the
bi-directional compensation structure is that no matter where the
medium flows out, the sliding sleeves at both ends of the
compensator always slide freely, so as to realize bi-directional
compensation and increase the amount of compensation.
Directly buried sleeve compensator application
The 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.
