It is a thermal fluid pipeline compensation device. It is mainly used to absorb and compensate the axial thermal expansion displacement that occurs after the auxiliary
linear pipeline is installed. It is a compensator directly installed in any pipeline that transports non-corrosive unidirectional or multidirectional fluid. The structure of the
sleeve compensator is mainly composed of sleeve (core tube), shell, sealing material, etc. It is used to compensate the axial expansion and contraction of the pipeline
and the axial rotation of any angle. It has the characteristics of small size and large compensation.
The advantages of sleeve compensators are explained as follows:
1. The sleeve compensator has a long service life, and the fatigue life is equivalent to that of the pipeline. The sliding surface is specially treated and has good corrosion
resistance in salt water, salt solution and other environments, which is more than 50 times higher than austenitic stainless steel. At the same time, when the sealing effect
is weakened due to wear after many years, the flange can be tightened again to enhance the sealing performance, or the bolt can be loosened, the pressure ring can be
removed, and one or two layers of sealing ring can be installed to compress the pressure ring. ,continue to use.
2. The sleeve compensator has no requirement on the chloride ion content, and is especially suitable for the system where the medium or the surrounding environment
exceeds the chloride ion standard.
3. The sleeve compensator is divided into one-way type and two-way type compensation structure. The feature of the two-way type is that no matter where the medium
flows from the compensator, the sliding sleeves at both ends of the compensator always slide freely to achieve two-way compensation and increase compensation. the amount.
4. The direct-buried sleeve compensator can be directly buried in the ground, and there is no need to set up a maintenance well during installation, so the project cost is low.
3. The inner sleeve of the sleeve compensator is connected with the pipeline, and adopts the principle and structure of high-performance self-pressure dynamic sealing. It can
slide freely in the shell with the expansion and contraction of the pipeline, which can meet the sealing requirements of any pipeline.
The installation method and precautions of the cylinder compensator are explained as follows:
1. When installing, check whether the model and specification of the compensator are consistent with the design, and the surface should be free from bumps, pressure pits,
severe corrosion and other defects that affect product quality.
2. During the installation of the sleeve compensator, do not let welding slag splash on the surface of the wave shell, and pay attention to protect the wave shell from damage
by other machinery.
3. For the two-way non-thrust compensator, it must be installed in the direction of the medium indicated in the diagram. When the medium is steam, it will avoid the formation
of air locks in the compensator. In order to ensure equal compensation in two directions of the compensator, the two-way compensator must be arranged in the middle of two
fixed points during design.
4. In order to ensure that the pipeline has no lateral displacement, it only telescopes in the axial direction, and a guide bracket is installed on the side of the telescopic tube.
When the two guillotines of the compensator have axial displacement, guide brackets should be installed on both sides to ensure that the axial displacement does not exceed
one degree of the eccentricity (+-) of the compensator.
5. When the total length of the disposable compensator is the same as the sample, it is not necessary to stretch or compress it. If the installation marking on the telescopic main
pipe changes, it should be adjusted before installation.
6. For compensators that need to be "cold-tightened", the auxiliary components used during pre-deformation should be removed after the pipeline is installed.
