Single unrestrained expansion joint consists of a single bellow, which is normally welded to a pipe, flange or with end fittings. This type of bellow can absorb small amount of axial, lateral as well as angulation movement.

These expansion bellows do not restrain pressure thrust, hence adequate anchors and guides must be provided.
