Steel Pipes - All about Pipes & TubesPPR Submersible Pipes

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 time of selecting PPR Flange Pipes & Coil Pipes for Submersible Pump following points are to be considered:

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

Head
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 expansion :
p = h SG / 2.31 (1)
where
p = pressure (psi)
h = head (ft)
SG = specific graveity

Converting 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)
where
h=head (ft)
SG = specific gravity

Converting pressure in psi to head in feet
h = p2.31 / SG (3)
where
h = head
p = pressure

Converting pressure in bar to head in meter
h = 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.
