U.S. Bellows, Inc. received this 26″ diameter pressure balanced elbow expansion joint for a complete refurbishment. The original condition of the expansion joint can be seen in the top image while the bottom image shows the expansion joint after being refurbished in just under 3 weeks. New SA-240 type 321 stainless steel bellows were used to replace the original bellows, and the tie rods and flow liners were also replaced. All carbon steel parts were painted with a universal primer. This expansion joint measures over 17 feet long center to center of elbows, and is currently being used in an effluent header at Cedar Bayou plant.
