TEFBELLOWS PTFE LINED EXPANSION JOINT

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.
