Clam shell bellows for a shell and tube heat exchanger.

US Bellows fabricated and installed a clamshell bellows for a shell and tube heat exchanger. The clamshell bellows are designed and fabricated per ASME VIII Div. 1 Appendix 26. It has a 14″ diameter and was designed at 150ºF and 150 PSIG. In order to detect any leaks, prior to and following forming, the heat exchanger and its welds were subjected to a series of tests, including a 100% dye-penetrant, x-ray, and air test.
