Steel Pipes & Tubes Industry.
of PPR Submersible Pipes :
» Long Life Span : 50 to 100
» Health : Hygenic and low bacterial growth.
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
» 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
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 :
time of selecting PPR Flange Pipes & Coil Pipes for Submersible
following points are to be considered:Maximum
Permissible Pump Delievery Head / Pressure
A term used to define water pressure in
vertical feet or meters.Converting head in feet to pressure in
Pump curves in feet of head can be converted to pressure - psi -
by the expansion :
p = h SG / 2.31 (1)
p = pressure (psi)
= head (ft)
SG = specific graveityConverting head in meter
to pressure in bar
Pump curves in meter of head can be converted to
pressure - bar - by the expansion :
p = h SG / 9.81 (2)
SG = specific gravityConverting pressure in psi to
head in feet
h = p2.31 / SG (3)
h = head
pressureConverting pressure in bar to head in meter
= p 9.81 / SG (4)
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 :
= (120 ft) 1 / 2.31
= 52 psiNote : Higher Presure rating
pipes upto 800' / 24 kgf/cm² and 1000 ft/30kgf/cm² are available
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
d = Depth (feet0
pt = Pressure required at top (kgf/cm²)
= 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.
D = [15-(3+1)x33']
=11x33 = 363'
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
