  1. Pressure Gauge – to monitor the pressure between the plies
  2. Inconel 625 LCF Two-ply Testable Bellows with Wire Mesh between the Plies – the wire mesh ensures flow from one side to the other side across the convolutions
  3. Carbon Steel Cover – pressure sealing in the even of bellows leak
  4. Control Rods – limits thermal movement
  5. 304 Stainless Steel Test Port / Valve – connection for air test of bellows
  6. Fire Blanket / KO Wool – keeps the bellows temperature above the dew point temperature of the flue gas (350°F to 450°F)
  7. Carbon Steel Lifting Lug – facilitates lifting
  8. Carbon Steel Shell
  9. 5″ Thick Vibra Cast Refractory – reduces shell temperature to 350°F
  10. 3/8″ Thick 304 Stainless Steel Liner with 3/4″ Thick Abrasion Resistant Refractory
  11. Ceramic Fiber Bellows Packing – reduces bellows temperature to under 1000°F
  12. 309 Stainless Steel Hose Braid Packed with Ceramic Fiber – seals the liner gap to prevent the catalyst from collecting in the bellows
  13. 304 H Stainless Steel – insulation box
  14. 304 H Stainless Steel Refractory V Anchors – secures refractory to pipe
