Expansion Joint Options

Expansion Joints are available in three configurations:

  • Flexible PFC with SS Shell
  • Rigid Bolted SS
  • Anti-rotation, Telescoping PVC

Positive locking bolted stainless steel couplings are suitable for drop pipes, stainless joints, and for all tube diffuser piping systems to restrict header pipe rotation.

Slotted Band

Slotted band joints with stainless steel shear rings are suitable for disc fine bubble and cap coarse bubble lateral plastic piping systems, in conjunction with SSI Aeration’s fixed and guide support stand system to manage thermal expansion and contraction.

Rigid Bolt Joint

SSI Aeration’s heavy duty expansion joint provides a double O-ring to prevent rotation, and allows limited longitudinal travel to absorb plastic pipe expansion and contraction.
