Fixed flanged type of expansion joints come with fixed (welded) flange connections supplied in accordance with many industrial norms (ASME, EN, DIN, JIS, AS, BS) or special drillings. In these units, flanges are either welded to a pipe or bellows. They cannot rotate.

They are suitable for higher pressure applications than rotating flanges where sealing can be of concern. It is a good practice to select the flange material as the same steel grade of the piping. Installers should be careful about flange bolt misalignment for existing pipelines. Welding in field is not needed.

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.
