Are there any codes or standards related to the inspection or design of metal bellows expansion joints for ductwork or any case histories of in service failures and their causes.
Thanks

There was a standard for duct work. I don't remember the number but we had a large waste heat recovery system that was built using the standard. The system had a lot of square or flued expansion joints.
If I remember correctly it was an like a subset of D-1.1.
Try 1.8 or 8.1

One number off.
The code is AWS D9.1M/9.1-2000.

appendix 26-5 , which deals with expansion bellow welds.
