Floating flanged type of expansion joints come with rotating (Vanstone) flange connections supplied in accordance with many industrial norms (ASME, EN, DIN, JIS, AS, BS) or special drillings. These units have rotating flanges on ends. This type of connection protects the flange from inside medium and minimizes flange bolt misalignments during installation of the expansion joint.

They are mainly used at lower pressure applications. This type is an excellent choice where inside medium is corrosive and use of a lower grade steel than bellows or piping can provide cost savings. With flanged type of connection, welding on site is not needed. They are not recommended where high pressures are present and leakage can be of concern.

This type expansion joints are commonly used at many industries and applications safely. They can be designed in single or universal expansion joint form depending on design conditions.
