Engineering & Design Services

Badger’s focus is on the design of fabric and metal expansion joints for industrial piping and ducting systems.  Our extensive expertise in the design development, forming, and testing of convoluted metal bellows, the key component of metal expansion joints, brings decades of advanced technology to the industry. Similarly, Badger has also made significant developments in fabric expansion joint technology.

Badger’s engineers employ a combination of proprietary bellows design software, CAD/3D modeling, and finite element analysis (FEA) to design metal expansion joints and hardware. These tools enable an analysis of bellows and hardware mechanical stress, pressure stress, movements, spring rate, cycle life, heat transfer, and process flow to validate the design integrity of metal expansion joints. Some of the same design tools are employed to validate the design integrity of Badger fabric expansion joints. Designs comply with the following codes and specifications when specified.

End Use Expansion Joint Application Experience  

Since 1916, when Badger designed and manufactured our first expansion joints, Badger has worked closely with engineers & constructors, original equipment manufacturers (OEMs), and directly with end users to provide expansion joints designed to specific end use process demands.  As a result, Badger has extensive experience with a wide variety of complex and demanding applications.
