Pipe expansion joint is a connector offering compensation in the pipe connection caused by heat bilges cold shrink. There are two kinds of pipe expansion joint most commonly used: rubber pipe expansion joint and metal pipe expansion joint.
characteristics of metal pipe expansion are of large amount compensation, under high temperature and under high pressure.
Install steel expansion has strict rules, when installation should pay attention to the fixed support setup and stress, on the fixed bracket crack and the expansion of telescopic pull side; Must design department design installation, otherwise pipeline prone to problems. Pay attention to guide bracket set range, the first guide bracket should be installed from the compensator is 4 times the distance, the second guide bracket should be installed from the compensator is 14 times, three points can be arbitrarily set.
Expansion joint can alleviate the blind thrust in pipeline operation, however, on the corner of the pump outlet and pipe, in the absence of the fixed piers, infinite piers and the slide pipe connection of directional limit bracket of piers should be adopted in the dowel joint and dowel joint spacing, avoid thrust to focus on pipeline corner or pump proximal, impact damage to equipment. Actually used in a variety of pipe, or use limit expansion (scale) and the pulled off limit, rubber joints, pipe of protection, especially to the pipeline installation and maintenance provides great convenience. And can use limit expansion joint and clamp flexible joint, because by dowel joint force bolt wire (that is, the whole bolt) can blind thrust the conduction of rev. When the pump to each part of the pump and pipeline, expansion joint, dowel joint, expansion pipe (slip) and flexible rubber joint, clamp joint (flexible clamp connector clamp connector) and quick joint in the pipe connection has a common effect, plays an expansion in the operation of the pipeline compensation displacement function.
