U.S. Bellows, Inc. designed and fabricated 2 EPDM tied expansion joints for a construction company in Texas. These expansion joints have an inside diameter of 29”. They are composed of A516 carbon steel grade 70 with a six-rod control assembly, EPDM, and plate flange. They were hydro-tested to 217 PSI. These joints were ordered on a one-week rush basis to replace an existing joint that was leaking.
