Verify the Condition of Flexible Hoses

Hazardous fluid release due to hoses failures. Wildly moving hoses at pressure release when coupling gets loose.

When Important

  • When using flexible hoses.
  • When disconnecting hoses that still contain pressure or toxic material.

Challenges in the Field

  • Connections are not properly made, requiring bended or stretched hoses.
  • No good storage location available.

Options to Get it Right

  • Make sure you use the correct hose: correct material of construction and temperature & pressure rating.
  • Visually inspect hoses before using them and check for defects like corrosion, wear or mechanical damage.
  • Hoses (including the connections) with hazardous fluids should be inspected periodically by an approved body and certified.
  • Avoid hoses for very toxic chemicals (like phosgene).
  • Hoses should be tagged and included in the maintenance schedule.
  • When not in use, hoses must be properly stored, with the appropriate bend radius, hanging straight down, or laying straight.
  • Hoses must not be twisted or forced when connected.
  • Connect hoses well, follow-up on possible vibrations.
  • If required replace hoses preventively and remove old hoses from the site.
  • Check correct depressurization of hoses before disconnecting.
