Flex Connector FBCFlex Connectors

  • Fault-free machine operation due to absorption of thermal and pressure expansions
  • Low fixed point stress due to small bellows external diameter
  • Corrosion-resistant material requiring little servicing
  • Compensation for installation tolerances due to optional lengths
  • Reduces structure-borne noise thus improving operating noise levels

Description

Is your furnace piping stressed out?!

Flex Connector BCWhen furnaces get hot, they need to stretch out (since hot metal expands). While the furnace grows, the pipework attached to the furnace does not. This is because the pipework has gas (and air) flowing at a constant temperature. The result? If you don't have flex couplings on your pipe, the pipe is forced to bend and stretch. Over time this leads to leaking pipes - and leaking pipes rob your process of the energy it needs. In severe cases, an unsafe condition results due to gas leaks!

Avoid this problem by installing flex connectors at every burner on your furnace. NFPA 86 requires it, it helps keep your furnace safe and productive, and it eliminates stressed-out pipe!
