Introduction: General installation method of sleeve compensator. 1. The sleeve compensator shall be properly kept during installation to prevent dust pollution, sun and rain. 2. During installation, check whether the model and specification of the compensator are consistent with the design, and the surface of the product shall be free from bumping, pitting and serious corrosion

General sleeve Compensator Installation method. 1. The sleeve compensator shall be properly kept during installation to prevent dust pollution, sun and rain. 2. During installation, check whether the model and specification of the compensator are consistent with the design, and the surface of the product shall be free from bumping, pitting, serious corrosion and other defects affecting the product quality. 3. When the total length of the disposable compensator is consistent with that of the sample, it is unnecessary to stretch or compress it. If the installation mark on the expansion main pipe is changed, it should be adjusted before installation.
4. For bi-directional non thrust compensator, it is necessary to install the medium flow direction indicated in the diagram. When the medium is steam, air plug will not be formed in the compensator. In order to ensure that the compensation of the two directions of the compensator is equal, the bidirectional compensator must be arranged between the two fixed points in the design.
5. The pipe section welded with both ends of compensator needs to be treated with break, and hydrostatic test shall be conducted according to the requirements after welding (the bolts at both ends of the packing chamber shall be tightened during pressure test until there is no leakage). After 24 hours of operation, the bolts at both ends of the packing chamber need to be tightened again.
6. In order to ensure that there is no lateral displacement of the pipeline, only along the axial direction, a guide bracket is installed on the side of the expansion pipe. When both compensators have axial displacement, guide supports shall be installed on both sides to ensure that the positive and negative (+ -) of axial displacement to compensator eccentricity does not exceed one degree.
7. The thermal insulation and waterproof structure of the compensator can be the same as that of the pipeline, but it can not produce binding force on the expansion section.
8. Special circumstances shall be discussed separately.
New sleeve compensator
1. When installing the compensator, first check whether its specification is consistent with the order.
2. The sliding sleeve of unidirectional compensator shall be installed at the inflow end of medium.
3. The pipe section welded between the new sleeve compensator and both ends of the compensator needs groove treatment. After welding, the hydraulic test shall be carried out according to the acceptance specification, and the pressure shall be 1.5 times of the working pressure. In case of leakage of sealing device during pressure test, the bolts shall be tightened evenly until there is no leakage.
4. The compensator is installed along the middle line of the pipeline, with different axial degrees greater than 1, so as to prevent excessive friction during operation and affect the sealing performance.
5. Guide sliding support shall be set at the pipe near the compensator to prevent lateral displacement.
6. Pay attention to protect the sliding surface, and do not damage or corrode.
7. The outer sleeve of bidirectional compensator shall be supported by fixed support and kept concentric with the pipeline, and the compensation distance on both sides shall be approximately the same.
8. The compensator can be installed in large length under various temperatures without pre tension or pre compression (the factory is the large length of the product)
