Product introduction: The single-type axial expansion joint is composed of a bellows and a structure. It absorbs the axial displacement of the pipeline and a small amount of lateral and angula1· displacement thrnugh the flexible deformation of the bellows. Both ends are connected or directly welded with the pipeline. 0「welded flanges and then connected with pipe flanges. The small tie rod on the compensator is used as a rigid support during transportation or as a product and deformation adjust-ment. and cannot be used as a tension rod for balancing the pressure and thrust. This type of structu「e is simple and the cost is low. so it should be considered first where the pipeline is available
