Lateral Expansion Joint

Lateral expansion joints are bellows expansion joints used primarily to absorb lateral movement. Lateral movement is perpendicular to the longitudinal axis of the pipeline, and the industry terms associated with it are axial movement and angular movement. Lateral expansion joints are one of the functional types of bellows expansion joints. In addition, there are axial expansion joints and angular expansion joints. Lateral expansion joints usually consist of two bellows elements and an intermediate tube. It is equipped with multiple tie rods on the outside to limit axial movement and resist the thrust caused by internal pressure. When the total installation length is given, the number of convolutions or the length of the intermediate tube can be changed to accommodate lateral movement.
