It is imperative that companies specifying and purchasing bellows give thorough consideration to the selection of the bellows material. Due to the fact that a given media will vary from system to system, and that most media specifications cannot accurately reflect what actually will occur during system operation, it is not appropriate for Piping Technology to make specific recommendations regarding bellows material.

If any doubt exists concerning proper material selection for the bellows, we recommend that a metallurgist with the appropriate basic material supplier be consulted.

Alloy 625 is a good material, it is  a GREAT material. It single handedly increased the life of FCC expansion joints and, in turn, helped extend refinery outage schedules over the last 25 years. The key was the huge improvement in acid corrosion resistance over stainless steel bellows.
