How to specify a hose

How to specify a hose

Whatever the application you are designing a hose for, it is essential to get the specification right to ensure optimal performance.

To make specifying a hose easier, utilise the STAMPED process.

STAMPED, which is an acronym of Size, Temperature, Alloy, Motion, Pressure, Ends and Distance, helps you consider the key requirements of your hose, ensuring the hose you specify, is fit for purpose.

STAMPED: Specifying a hose

Size

Check for:
- Inside diameter
- Outside diameter

Temperature

Check for:
- Temperature of the material being conveyed (i.e. high, low, ambient)
- Temperature of the external environment
- Whether the temperature is intermittent or constant

Alloy

Check for:
- Service temperature range
- Strength
- Corrosion resistance
- Chemical compatibility

Motion

Check for:
- Static (one time routing) or dynamic motion (flexing and cycling)
- Vibration
- Minimum bend radius

Pressure

Check for:
- Maximum working pressure
- Safety factor and burst pressure
- Flow rate
- Impulse or pressure surges

Ends

Check for:
- Male or female
- Fitting type and material
- Swivel or non-swivel
- Orientations and alignment

Distance

Check for:
- Hose length (overall, live length, seat to seat)
- Tolerances
