Single Tied: Single tied bellows is a single bellow but with an addition of tie rods. The tie rods are normally attached to the end pipes or flanges with lugs that carry pressure thrust of the system. This thus eliminated the need of main anchors....

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,...

Hinged bellows are used where angular movements are required. Although hinged bellows angular movement is limited in one plane. These kinds of bellows are often used in sets of two or more to absorb large movements. Hinge bellows absorb pressure thrust of the system, hence...

Universal un-restrained expansion joint consists of two bellows, connect by a central pipe either with flanges or pipe ends. This type of expansion joint can absorb greater amount of axial, lateral and angular movements. By increasing central length of pipe, greater movements can be achieved....

Universal tied bellows is a dual bellow but with an addition of tie rods. The tie rods are normally attached to the end of pipe or flanges with lugs that carry pressure thrust of the system. On top of this the tie bars also limit...
