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, clamshell expansion joint for a chemical plant in Beaumont, Texas. The chemical company utilized U.S. Bellows’ 24 x 7 Quick Turn/Emergency service.

Quality Control Performing Dye Penetrant Test

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 750oF. 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.
