Flexible Connectors

Whether your concern is thermal expansion or vibration isolation, BAM Flexible Connectors are the right solution. Industrial-grade construction ensures long life and dependable operation. We deliver when you need it. 

BAM Flexible Connectors are custom sized to fit your application and your equipment. With sleeve depths of 3" to 36", we will design and fabricate rectangular and round connections for inlets and discharges of any manufacturer's fan or any size ductwork. 

Allowing for Thermal Expansion

At 1000°F, typical stainless steel expands almost 1/8 of an inch per foot in length. That means a 10-foot section of ducting will grow by more than an inch. Even at 650°F, a 10-foot run of mild steel ducting will grow by half an inch. Without a flexible connector to absorb the expansion, a fan housing can be twisted and distorted. In some cases, the fan housing can even be pushed into the rotating fan wheel. 

Construction Specifications

BAM Flexible Connectors can be constructed using various types of materials for flanges and sleeves. 

Flanges can be constructed from:

  • Mild steel
  • 304 stainless steel
  • 316 stainless steel
  • Galvanized
  • PVC
  • Aluminum

Sleeves can be constructed from:

  • Teflon-coated fiberglass
  • EPDM
  • Nitrile
  • High temperature Teflon construction
  • Other materials, if required

Performance Specifications

BAM Flexible Connectors can accept misalignment well beyond normal duct alignment tolerances. Up to 1" offset over an 8" sleeve length is acceptable and satisfactory service may be realized with even worse misalignments depending upon airstream velocity, turbulence, and other factors. 

Vibration transmission through the connector is negligible, to the point where other system factors will be the dominant source. 

Connectors are not designed to be load-bearing.
