This type of bellow is made up of two bellows joined together by a central pipe. Although it can be used to absorb any combination of the three basic movements (axial, lateral, angular), it is mainly used to absorb large lateral movements. Again, this type of bellow does not restrain pressure thrust so adequate anchors and guides must be provided and they can be used only in piping systems that incorporate correctly designed anchors and pipe alignment guides.
- Size Range: 2" till 24"
- Maximum Operating Pressure: 20 bar (dependent on diameter)
- Type of Flanges: BS, JIS,DIN,ANSI
- Flanges material upon request (SS 316, SS304, Carbon Steel, Mild Steel)
*Metal Expansion Joints may be supplied with tie- rods. Provided in sets of two or more, they are equally distributed around the circumference of the expansion joint to withstand the thrust produced by internal pressure.
