Rectangular expansion joints

Rectangular Metal Expansion Joints are generally used to convey fumes from the boiler to the chimney or steam from the turbine to the condenser. They have rectangular passage areas. Rectangular Metal Expansion Joints have one or more convolutions for low and medium pressures and full vacuum services.  The connection elements are available either with flanges or welding ends.

Regardless of accessories, such as liners and covers, the rectangular metal expansion joints absorb all of the movements in any one length of piping but it is mainly used to absorb axial movements.

The rectangular metal expansion joints 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.
