Metal Hose Terminology
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 to other components. Such as flanges, unions, nipples, etc. FLOW VELOCITY - When the flow velocity exceeds 75 ft./ second liquid,
150ft. / 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 assemble
should be subject to for testing purposes. 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. RATED BUST PRESSURE - Pressure at which hose can be expected to fail.
Braid will normally fail before core burst. SAFETY FACTOR - Difference between working pressure and rated burst
pressure. SHOCK OR PULSATING PRESSURE - Sock, 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 motion. WORKING TEMPERATURE - Temperature to which hose will be subjected
during operation.
