Annular – A Hose profile that is designed so each convolution is a separate circle or ring.
Braid – Woven wire cover placed over hose which prevents elongation of the hose and permits higher working pressure.
Close Pitch- More corrugations per foot which renders the longest fatigue life and minimum bend radius.
Constant Flexing Bend Radius – The minimum radius to which a hose can be repeatedly bent and render satisfactory flexure life.
Constant Motion- Motion that occurs on a regular cyclic basis at a constant travel.
Fittings- Parts attached to the ends of metal hose so that it can be connected other components such as flanges,unions, nipples,etc.
Flow Velocity – When the flow velocity exceeds 75 ft./second liquid, 150 ft./second gas in braided hose, a flexible metal liner should be used.
Intermittent Motion – Motion that occurs on a regular or irregular cyclic basis.
Maximum Test Pressure – Maximum pressure hose assembly should be subject to for testing pruposes. Based on 150% of the Maximum Working Pressure.
Media – Conveyant in a hose assembly such as gases , liquids, etc.
Operating Conditions – Temperature,Pressure, Media,Motion and Application involved.
Random Motion - Uncontrolled motion that occurs usually from manual handling of hose.
Relad Burst Pressure - Pressure at which hose can be expected to fail. Braid will normaly fail before core burst.
Safety Factor - Difference between working pressure and rated burst pressure.
Shock or Pulsating Pressure - Shock,pulsating or surge pressure can cause premature failure of hose.
Static Bend - Minimum center bend radius to which flexible metal hose may be bent for installation.
Vibration - High frequency,low amplitude.
Working Temperature - Temperature to which hose will be subjected ruing operation.
