OVERVIEW: The Tefbellows is an expansion joint that combines the properties of metal and PTFE into the most advanced, versatile expansion joint available. Normal design temperatures from -300F to +400F, in pressure ratings of 50, 150, and 300psi or higher. Great for highly corrosive chemical-petrochemical systems at elevated temperatures.
Unlike ordinary solid PTFE of elastomeric type expansion joints like our Tefspool, should up-set conditions exceed 500F, the Tefbellows will retain it’s pressure carrying capacity up to 1200F, sufficient time for system shut-down and replacement.
The integral PTFE liner follows the metal bellows convolutions, which can be made of 316 stainless steel, Inconel, and other metals.
