Introduction: It can prevent the leakage or damage of compensation joint caused by excessive displacement. It is mainly used for loose sleeve connection of pipeline absorbing axial displacement and bearing pressure and thrust within the allowable displacement range. It is suitable for connecting one side with flange and the other side welding with pipeline, and adjusting products during installation

It can prevent the leakage or damage of compensation joint caused by excessive displacement. It is mainly used for loose sleeve connection of pipeline absorbing axial displacement and bearing pressure and thrust within the allowable displacement range. It is suitable for one side connecting with flange and the other side welding with pipeline. During installation, the installation length between both ends of the product and pipeline or flange is adjusted, and the gland bolts are uniformly tightened diagonally, Expansion joint Then adjust the limit nut, so that the pipeline can freely expand and contract within the scope of expansion, lock the expansion amount, and ensure the normal operation of the pipeline.
The commonly used thermal insulation material is rigid polyurethane foam plastic, which is suitable for - 185 ~ 95 ℃ and can bear the axial pressure of the pipeline. In this way, the installation and maintenance can be adjusted according to the on-site installation size. During the operation, it not only improves the work efficiency, but also plays a protective role on the pipeline equipment such as pumps and valves, and can freely rotate a certain angle within 360 degrees And the seal can automatically compensate, so as to effectively eliminate the leakage, and the effective limit mechanism can avoid Telescopic device The pipeline can run stably when the expansion and contraction are exceeded.
However, at the pump outlet and pipe corner, the sliding pipe connection without fixed pier, infinite pier and directional limit pier support should be adopted Force transfer joint And limit force transmission joint, or use Limit expansion device (expansion joint) and anti pull off limit Rubber joint Limit expansion joint and clamp flexible joint can be used, because the force transfer joint can transmit the thrust of blind plate when starting the pump to all parts of the pump and pipeline through the force transmission bolt (i.e. full wire bolt), so as to avoid the thrust concentrated on the corner of the pipeline or the near end of the pump, resulting in impact damage to the equipment.
If the length is too short or too long, it will not be worth the loss. The installation direction of the double flange limit expansion joint will be indicated on the outside of the expansion joint before delivery, and the technical personnel shall mark the installation direction, especially for the expansion joint with large diameter and large pressure. There is no regulation on the installation position of the limit expansion joint in our country, and it is generally correct The normal installation of the limit expansion joint is very balanced with the pipeline, but some manufacturers will install the limit expansion joint too high.
