Several requests had been made for engineering guidelines regarding metal bellows seals.  Although I like metal bellows seals, I don’t consider myself expert in their design.

SealFAQs does include some comments and anecdotes about metal bellows seals including the history and development of stationary metal bellows seals but no real details about design or application.

Fortunately, John Crane has recently published “Seven Things to Know …” about metal bellows seals in their blog.
