How To Extend The Life of Your Hose
Below are some ways you can extend the life of your hose. Our Hose Advisory Services can help with this and much more in order to become a best-in-class facility.
Establish an inspection schedule based on system application and replacement history.
Static electricity can be generated by fluid passing through the hose. Select hose with sufficient conductivity to ground the static electric charge.
Evaluate amount of system vibration when selecting hose. Metal hose may not be appropriate for systems with constant or severe vibration.
Take into consideration hose movement, system pressurization, and thermal expansion when determining hose length. Installing hose that does not have sufficient length to accommodate these factors may reduce hose life.
Minimum Bend Radius
Follow minimum bend radius requirements for your hose. Installing hose with smaller bends may kink hose and reduce hose life. Hose rupture or leakage may result from bending too close to the hose/fitting connection.
Elbows and adapters can be used to relieve hose strain.
Distribute movement and prevent bends smaller than the hose’s minimum bend radius by providing sufficient hose length.
Allow for changes in length resulting from machine motion and tolerances.
System Pressure Changes
Allow sufficient hose length to accommodate changing system pressures. Do not connect high- and low pressure hoses.
Bending in One Plane
Avoid twisting the hose by bending it in one plane only. For a compound bend, use multiple hose pieces or other isolation methods.
