uPVC Column / Riser / Drop Pipes

APPLICATION

Atul is pioneer to design develop and market uPVC Riser/Drop/Column that are being successfully used in the erection of submersible borehole pumps up to depth of 1000 feet. More than 2,00,000 successful installations have taken place across the globe.

ADVANTAGES OF ATUL uPVC RISER/DROP PIPE

• Cost Saver
• Power Saver

10% to 80% extra water* discharge compared to steel pipes
No Electrolytic Deposition

SQUARE TYPE THREADS

The joint of pipes have been specially designed with square threads to ensure proper gripping and no change of slipping. These threads are high friction threads on load, which do not open even on constant forward and reverse torque generated by starting & stopping the pump. They are made on specially imported CNC machines with high accuracy tool to ensure perfect dimensions and good & easy fitment. All threads are checked thoroughtly with fitment gauges to ensure 100% accuracy.

RUBBER RING

An outer rubber ring is provided in the T (Temporary) side of the pipe and an inner rubber ring is provided in the P (Permanent) side of the pipe which ensures a 100% leak proof joint.

BI-AXIAL ORIENTATION

Bi-axial orientation during column pipe extrusion. Atul has developed a unique Bi-axial onotation technique used during pipe extrusion, which gives higher drop impact and notch impact strength to the pipes. This onenation technique is a result of constant Research and Development at Atul only.

THICK & THIN

Unique thick & thin construction of pipes. This innovative technique for making pipes thicker in the threading end to compensate for material removal due to threads an innovation made only at Atul.
The residual thickness (1) in the end part after removal of thread is the same as barrel thickness (t). Therefore the pipe strength remains the same.

This technique saves on the raw material consumption and at the same time provides much higher strenght to the pipes.

Comparative Chart

Sr. No.	Property requirement for Drop / Riser Pipes	ATUL PIPES	Mild Steel or Galvanized Steel Pipes	HDPE Pipes
1.	Rigidity requirement so that Drop / Riser pipes & pump is vertical for proper NRV function	Pipes are rigid	Pipes are rigid	Pipes are flexible hence not suitable for Drop/Riser application. Pipes are also soft & over long term use with heavy pump set they elongate & loose their shape permanently. In the process of elongation they become thin & break.
2.	Strong threaded joints required for holding the column & submersible pumpload.	Specially designed square threads have very high load holding capacity & these threads do not corrode or rust or detoriate.	The threads are prone to corrosion & rusting. Since the threads do not have a layer of Galvanisation, after 2-3 years of use the old thread have to be cut out & new threads have to be made on the pipes on lathe machine due to rusting problem. Money & effort is spent in making new threade and the user ends up with a shorter length of pipe.	The threade cannot be formed as these pipes are soft and therefore the jointing of the pipe with the pump or at the top with and fixture is simple push type joint.
3.	Leak proof joint required for saving every drop of water.	Special rubber seals are provided with the thread to ensure 100% leak proof at high pump pressure.	These threads are not pressure tight and do not have any rubber sealing system. Therefor not leak proof.	Threads are weak & open up during use.
4.	Smoth Internal Surface.	Since the internal surface is very smooth therefore head loss due to friction is low any water discharge is more by 100% – 30%.	Internal surface is rough & head loss is high.	Internal surface not as smooth as Atul Pipes
5.	Light weight of pipe & ease in installation.	Pipes come in 3 metres standard length and are light weight for easy handling both during pump fitment and also removal.	Pipes are heavy and great effort is required for installation and removal of pumps. In deeper bore wells the column of pipe becomes very heavy and are prone to accidents during handling.	Becomes hard and can not be rolled back during removal. Pulling with tractor disturbs the crop.
6.	Long life	Atul Drop/Riser pipes do not reach with acidic or alkaline water and also have a very long life inside the bore well.	Steel pipes are prone to rust, corrosion & ultimately get damaged and have to be replaced very quickly.	Strength of material being very less, very thick pipes are required for high pressure application. This reduces the internal area for water flow considerably. Hence thin pipes are used for high pressure application and the pipes burst in 2-3 yrs.
