# PPR Pipes Technical Data

At the time of selecting fusion® PPR Flange Pipes & Coil Pipes for Submersible Pump following points are to be considered.

 Pipe Series Delivery Head Pressure Economy 250feet 9kgf/cm2 Light 400feet 12kgf/cm2 Medium 500feet 15kgf/cm2 Heavy 625feet 18.75kgf/cm2 Extra Heavy 800feet 24kgf/cm2

A term used to define water pressure in vertical feet or meters.

 Converting head in feet to pressure in psi Pump curves in feet of head can be converted to pressure - psi - by the expression: p = h SG / 2.31 (1) where p = pressure (psi) h = head (ft) SG = specific gravity Converting pressure in psi to head in feet h = p 2.31 / SG (3) where h = head (ft) p = pressure (psi) SG = specific gravity Converting head in meter to pressure in bar Pump curves in meter of head can be converted to pressure - bar - by the expression: p = h SG / 9.81 (2) where h = head (m) p = pressure (bar) SG = specific gravity Converting pressure in bar to head in meter h = p 9.81 / SG (4) where h = head (m) p = pressure (bar) SG = specific gravity

Example - Converting Pump Head - feet - to Pressure - psi.

The pressure - psi - of a water pump operating with head 120 ft can be expressed as:
p = (120 ft) 1 / 2.31
= 52 psi

Note: Higher Pressure rating pipes upto 800'/24kgf/cm2  and 1000ft/30kgf/cm2 are available on request.

The delivery pressure of the pump should never exceed the working pressure of the pipes connected to the pump at the bottom as under:

DEPTH CALCULATION OF BOREWELL AND PRESSURE RATINGS

Let:
d = Depth (feet)
pt = Pressure required at top (kgf/cm2)
pp= Pipe pressure Rating (kgf/cm2)

Depth = [pp – (pt+ph) x 33']

For example:
If fusion medium pipe of 3'' is used and pressure required is 3/kgf/cm2 at top.
Hence

D = [15-(3+1) x 33']
=  11 x 33= 363'

So pipe can be lowered up to 363 feet.

Note: Higher Pressure rating pipes upto 800'/24kgf/cm2  and 1000ft/30kgf/cm2 are available on request.
