Within a three day span, U.S. Bellows, Inc., the expansion joint division of Piping Technology & Products, Inc., fabricated a 40” I.D., single coded, clamp shell expansion joint for a chemical plant in Beaumont, Texas. The chemical company utilized U.S. Bellows' 24 x 7 Quick Turn/Emergency service.

After the representative from the chemical plant completed the online form, the U.S Bellows' “on-call” team was immediately paged. Three days later the bellow had been successfully fabricated, welded to an A516-70 heat exchanger shell and shipped to the chemical plant to resume operation. The bellow was fabricated from A240 tp 321SS and designed at 50 PSIG and 750^oF. In order to detect any leaks in the weld, the bellow's long seam weld was 100% x-rayed and its attachment weld was 100% dye-penetrant.
