RESEARCH AND DEVELOPMENT
–-–
We maintain the only fully equipped laboratory of its kind in the expansion joint industry. It is dedicated to
bellows materials research and analysis. In addition, we have the largest and most comprehensive testing
facility available. We routinely perform vibration testing, cyclic fatigue testing, seismic shake analysis and
cryogenic and elevated temperature testing.
A substantial portion of each annual budget is
devoted to research into new and improved
methods of bellows forming, verification of bellows
properties, validating calculations and development
of new EJMA equations. New bellows materials and
pressure thrust restraint structures are also
evaluated. As a result, Senior Flexonics Pathway is
the leading innovator in expansion joint design.

MANUFACTURING
–-–
Senior Flexonics Pathway is the only major metal
expansion joint manufacturer that regularly uses all
recognized bellows forming technologies, including,
hydroforming, expanding mandrel or punch forming,
roll forming and elastomer forming.
We use the optimum forming method to
make the best expansion joint bellows
for the application.
