Advantages
of PPR Submersible Pipes :» Long Life Span : 50 to 100
years.
» Health : Hygenic and low bacterial growth.
» Easy
to install : Conventional Jointing system.
» Easy transport &
handling : Low specific weight.
» Extra Flow : Low head loss due to
extra smooth inside surface of Pipe.
» Low electric consumption :
Due to less pumping hours.
» Resistence to avrasion : Even with
high flow velocity & higher PH values & corrosion of water.
»
Taste & odour neutral.
» No blockage, No rust, No
crystallization for lime deposits to cling.
» Earth quake resistent
pipe : Flexibility & resilience of material allows their use in seismic
area.
» Re-useable piping system : Can be reused for several times.
Extra length of PPR flange pipes are
available in 3 Mtrs. standard size. Keep on adding as required. Extension
Piece is to be joint at both the ends. Extension Piece is required at bottom
for pump assembly & at top for fittings assembly.Perfecct
Jointing System with worldclass Raw Material :»
Conventional Jointing System : This System is well known tried &
tested.
» MS Coated Flange : Provided for extra
strength.
» Dowel Pin : For binding of MS and PPR
flange together to strengthen the assembly.
» O Ring :
Made of very high quality rubber to prevent leakage.
»
Spring Washer : Spring Washer given to absorb vibration of the
pump.
» Product Range : 32mm to 160mm
1
inch to 6 inch
» Bearing Capacity : 500 Kgs. to 2000 Kgs.

PPR Pipes for submersible Pump can resist pressure of 6 Kgf - 25 Kgf (as per
pressure norms).Technical Data :At the

Head A term used to define water pressure in
vertical feet or meters.
Converting head in feet to pressure in
psiPump curves in feet of head can be converted to pressure - psi -
by the expansion :
p = h SG / 2.31 (1)
where
p = pressure (psi)
h
= head (ft)
SG = specific graveity
Converting head in meter
to pressure in barPump curves in meter of head can be converted to
pressure - bar - by the expansion :
p = h SG / 9.81 (2)
where
h=head
(ft)
SG = specific gravity
Converting pressure in psi to
head in feeth = p2.31 / SG (3)
where
h = head
p =
pressure
Converting pressure in bar to head in meterh
= p 9.81 / SG (4)
where
h = head (m)
p = pressure (bar)
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 Presure rating
pipes upto 800' / 24 kgf/cm² and 1000 ft/30kgf/cm² are available
on request.THe delievery 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 (feet0
pt = Pressure required at top (kgf/cm²)
ph
= Head Loss (1 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 presure required is 3/kgf/cm² at top.
Hence
:-
D = [15-(3+1)x33']
=11x33 = 363'
so pipe
can be lowered up to 363 feet.
Note : Higher Pressure rating
pipes upto 800'/24 kgf/cm² and 1000ft/30 kgf/cm² are available on
request.
