DESCRIPTION

Hydraflex’s smooth bore EPDM lined assemblies with a 304 Stainless Steel over braid have been independently tested and permitted for potable water by The Water Regulations Approval Scheme (WRAS). Available from DN08 to DN25 and a temperature range of -20°C to +110°C, these assemblies are differentiated by a red fleck through the over braid from our standard building services assemblies.

APPLICATIONS

  • Potable Water
  • Drinking Water

HOSE DATA

ASSEMBLY MEASUREMENTS

HOSE REDUCTION THROUGH FITTINGS

The arrow on drawing D2 denotes the ‘R’ measurement showing the ‘Minimum Bore Through Fittings (mm)’ which is reduced through the fitting tail, with a tolerance of +/- 0.2mm. The below measurements represent the minimum bore of each DN size; however, fittings will vary in bore size. For further information regarding this please contact out technical department.

MINIMUM BEND RADIUS

WORKING AND THEORECTICAL BURST PRESSURE

PRESSURE DROP

Formula: Pc = (TxL) + R (in mbar)


Pc = Pressure Drop in mbar
T = Pressure drop in mbar for one meter of hoses according to its flow capacity in M3/h (Schedule 1)
L = Hose Length in meters
R = Pressure drop in mbar caused by two fittings (male x female), same condition than ‘T’ (Schedule 2)

Flexible hose with one straight and one elbow fittings= R x 1.5
Flexible hose with two elbow fittings = R x 3
Example:
Flexible hose DN13 length 500mm 1 FP – MC, flow capacity 1000 l/h
Pc = (26 mbar/m x 0.5m) + 23 mbar = 36 mbar
Flexible hose DN25 length 800 1 FP – FPN, flow capacity 1500 l/h
Pc = (3mbar/m x 0.8m) + (2.5 mbar x 1.5) = 9 mbar

Note: ‘T’ value only valid for hoses installed straight. Installation with bend can cause pressure drop relative to decrease in bend radius.
