UFBX Standard Hose Fittings & Flanges
Application
Static installations – where the flexible is used to connect pipework out of alignment and remains in a static position.
Occasional flexing – when the hose is required to flex continuously, usually on
moving machinery.
Vibration – high frequency, low amplitude movement, e.g. on a compressor or pump.
Description
An ISO 10380 specification medium pressure hose.
- Specifically designed to meet the requirements of ISO 10380 flexibility class 1
- Most of the range can be supplied on drums for easy handling or where continual lengths are needed.
- Will convey all manner of liquids and gases.
- High physical strength
- Long life
- Good corrosion characteristics
- Suitable for elevated temperatures up to 600ºC or in cryogenic applications down to -200ºC
- Manufactured to BS 6501 Part 1, 2004 flexibility class type 1.
Construction
The hose are annually corrugated formed from butt welded rigid tube. Depending on the application, required working pressure and conditions of operation, a single or double layer of wire braid can be applied externally to the hose to restrain it, increasing its ability to withstand pressure, increasing hoop strength and protection from abrasion. The extent of braided, gauge and angle lay is calculated carefully to maximize performance.
MATERIALS
Tube: BS EN 10088 -2:2005 1.4541 (321S31) or 1.4404
(316S11)
Braid: BS EN 10088-3 :2005 1.4301 (304S31) or 1.4401
(316S11)
SHOCK PRESSURE
Pulsating, surge or shock pressures considerably affect hose longevity and if encountered, peak pressure must not exceed 50% of the maximum working pressure.
FLOW VELOCITY
High velocities should be avoided as they can lead to premature fatigue failure.
An interlock hose should be used as a liner if velocity exceeds:
Unbraided: 30m/s (gas); 15m/s (liquid)
Braided: 45m/s (gas); 22.5m/s (liquid)
When the hose is installed in a bend condition, these values should be reduced by 50% for a 90º bend, 25% for a 45º and so on, proportionally to the angle. With higher velocity, the next larger hose with liner should be used.
PRESSURE LOSS
To achieve the same pressure loss as in steel pipes, the diameter of the corrugated hose should be increased by 15%.
PRESSURE DERATING FACTORS
The pressure ratings given apply to hose with welded end connections at room temperatures. The following derating factors must be applied at higher temperatures.
