Double hinged expansion joints consist of two bellows with pipe ends or flanges.  This type of expansion joint come with a central pipe and double hinges to absorb pressure loads created by internal pressure – hence the pipeline does not require strong anchors.  Double hinged expansion joints can only accept angular and lateral movements in one plane.
