The primary purpose of a typical expansion bellows is to isolate a fluid from neighboring components. Bellows are used in a variety of applications, including pulse dampeners, HVAC systems, pharmaceutical processing, pollution control, and piping systems. PTFE (polytetrafluoroethylene, or Teflon) is an ideal material for bellows applications, and in this post we are going to explore seven things every engineer needs to know about PTFE bellows.
