The U.S. Bellows exhibit featured a cut-away view of an expansion joint with insulating and abrasion resistant refractory lining and miniature models of various types of metallic expansion joints. Discussions at the booth included how to solve regenerated catalyst and spent catalyst standpipe expansion joint reliability problems. Talk to the engineers at U.S. Bellows about your flue gas expansion joint problems. We can help with your fabric expansion joint problems in low pressure flue gas systems.
