Velocity in Metal Hose

When gas or liquid being conveyed in a corrugated metal hose exceeds certain limits, resonant vibration can occur. Resonance may cause very rapid failure of the assembly. In those applications where product velocities exceed the limits shown in the graph below, a revision of the assembly design might include:

  1. Addition of an interlocked metal hose liner.
  2. An increase in the corrugated hose I.D.
  3. A combination of the above.
