Light weight: PVC pipes are light in weight hence transportation and installation becomes much easier.
Hygienic: As uPVC is immune to galvanic and electrolytic erosion, both pipe and water passing through it is not affected and hence water is not contaminated.
High flow rate: Mirror smooth inside surface of pipe and corrosion resistance property prevents scale formation which ensures high flow rate resulting in substantial power saving. They can be installed in all types of acidic or alkaline medium which badly affect metal pipes.
Longer life: Utkarsh pipes are manufactured with latest technology under stringent quality control. Specially imported additives are used for higher strength and trouble free long service life.
High Tensile Load Capacity: Specially designed square threads (male and female) are manufactured on SPM’s to provide smooth fitment/refitment. The design of threads along with the pipe material makes it strong enough to take high tensile loads.
Leak proof joints: The sealing rings are made from best quality rubber which ensures long service life, absorption of pump vibration and leak proof joints.
Overall economy: In addition to the above benefits, Utkarsh column pipes for submersible pumps are much economical to G I pipes.
Utkarsh Column pipes have been specially designed and manufactured under stringent quality standards. They are tested to withstand system load comprising of pump, water and pipe weight with adequate factor of safety, they can withstand considerable shocks and jerk load during operation due to unique design of square threads
Installation Procedure and Precautions
Take 3 meter long pipe, remove the protection cap from male end. Wipe both male and female threads, clean using piece of cloth.
Ensure that rubber gasket supplied with the pipe is property placed in the groove on the male threads of pipe.
Tighten the CI bottom adapter on the pump with the help of strap wrench or pipe wrench. Lower the pump in the well using loop bail or MS clamps.
While lowering or extracting the pump set, pipes should be clamped at ‘’CLAMP HERE’’ location marked on the pipes. Rubber sheet/cushioning between pipe surface and clamp may be used to avoid scratches/damages to the pipe.
Clamps to be used with pipe for installation should be of correct size (as shown) to avoid damages to the threads.
Use of Utkarsh Column pipes for submersible pump in combination with GI Pipes in the same bore well/tube well is not recommended.
Assemble pipe one after the other. Tighten pipes by strap wrench or jerk of a pipe wrench so that 50% of rubber-sealing ring on male thread end gets into the seat of belled/coupler female square threads. Use plain water or soapy water as a thread lubricant. Do not use any oil or grease on threads.
When the pump is lowered to desired depth, fit top adapter to the last pipe. Connect required fittings like nipple/bend to the delivery side of top adaptor.
Use Utkarsh installation tool i.e. loop bail for lowering the pipes in the bore well while using tripod and chain pulley block instead of MS clamps.
We recommend use of Utkarsh pump guard system to make your installation full proof against falling of pump due to excessive vibration/ jerks or during pump withdrawal.
Do not over tighten the pipes as it will result in crushing of rubber sealing leading to leakage / Pipe failure
Use new Rubber seals for every reinstallation of submersible pump.
If lubrication is needed to ease the joint assembly, plain water or soapy water can be applied to the threads prior to assembly.
Do not apply grease, oil or any other oily substance on the threads.
It is advisable to use safety device such as pump protection relay to prevent dry running of pump or pump shut-off head condition.
A safety cable or rope should be used to prevent dropping of pump in the well either during operation or withdrawal. The rope can be of steel or nylon or polypropylene.
In bore wells with loose boulders, casing pipes are recommended for entire depth.
In bore wells, without full casing pipes, it is advised that at the time of removal of pumps for bore well ,if the pump gets stuck up due to silt/sticky mud or entrapped stone, proper flushing of the bore well should be done and only then pulling load should be applied to the pipes for pump removal.
Use of good quality reflux valves on the delivery side is recommended for preventing water hammer, up thrust and back spin in the pumping system.
Pipes: The column pipes are available in 1’’ ,1 ¼’’ , 1 ½’’,2’’, 2 ½’’,3’’ and 4’’ in different classes. Pipes have female belled threads at one end and male threads on the other end and/ or with separate coupler as per the details given in the table. Pipes are available in 3 meter length with square threads fitted with rubber sealing ring at male threaded end.
