Limit expansion joint in the pipeline industry to improve the efficiency of use

Expansion joints mainly consist of flexible compensators and joints, whose main function is to compensate for the deformation and connection and expansion of the pipeline, reduce the deformation of the pipeline system, reduce the internal stress of the pipeline, prevent the pipeline system and equipment damage caused by thermal expansion and contraction, and ensure the normal operation of the equipment. The expander can make the pipeline reduce the project cost and extend the service life, but also play a role in preventing and reducing the damage to the pipeline system. It also greatly reduces the project cost.
The flange bolts to which the double flange limit expanders are connected must be tightened, and their nuts must not be pulled off causing the expanders to vibrate. The direction of rotation of the expansion joint should be opposite to the installation direction to ensure the amount of displacement deformation in that direction of rotation. Therefore, the rotating expansion joint must be installed in the pipe. During installation, care must be taken that there is no gap between the connecting flange and the expansion joint, while the installed sealing rubber ring must be completely sealed to ensure the normal operation of the expansion joint.
During installation, the fastening screws must be tightened according to the standard size and no loosening should occur. In order not to lead to the vibration of the expander, thus affecting the normal work and use of the expander. In addition, the double flange limit telescope needs to be installed on the pipeline during installation, not on the non-load-bearing parts, because the rigid support cannot make it undamaged, so it should be fixed. If there is damage should be timely repair and replacement to avoid the pipeline due to pipeline displacement caused by pipeline and equipment accidents on the work caused serious losses.
