The single-flange limit expansion joint is composed of loose sleeve expansion joints and limit short pipes. Prevent leakage or damage of compensation joints caused by excessive displacement of pipelines. It is mainly used for loose sleeve connection of pipelines that absorb axial displacement and bear pressure thrust within the allowable displacement range. It is suitable for flange connection and pipeline welding at the same time. Adjust the installation length between the two ends of the product and the pipe or flange. Tighten the gland bolts diagonally and evenly. After adjusting the limit nut, the pipe can be freely expanded and contracted within the range of expansion and contraction, and the expansion and contraction can be locked to ensure the safe operation of the pipeline.
Working principle of limit expansion joint:
The limit expansion joint is also called the limit expansion joint. After it is installed on the pipe, tighten the elastic sealing ring of the nut. Under the action of the nut gland, the elastic sealing ring is tightly pressed on the outer ring of the pipe through mutual oblique degree to play the role of sealing and connection.When the temperature changes, the pipe can be freely telescopic in the middle of the joint. When the foundation sinks, the pipe can be deflected, so that the telescopic joint seal has no leakage and plays the role of automatic compensation.
