If you look closely at the restraining hardware (tie-rods) on these expansion joints, you’ll see there are no outboard nuts. That means these EJs are exerting their full pressure thrust upon the adjacent piping. Apparently the elbows below them are handling it well, as they’ve been installed for 15 years.
