Submersible pump installations used GI for decades — and dropped pumps for decades. PVC column pipes ended that.
A submersible pump hangs from its column pipe — sometimes 200 m down a borewell. If the column fails, the pump falls and recovery costs more than the entire installation. That's why every modern borewell uses PVC column pipes to IS 12818, not corrosion-prone GI.
Why PVC Column Replaced GI
GI rusts in the borewell within 3–5 years; PVC stays bright for 25+ years.
Square-thread couplers carry full pump weight with zero leakage.
1/4th the weight of GI — single-person installation possible.
Smooth bore — better discharge, less power per litre lifted.
Pressure Classes Under IS 12818
Series 1 — for depths up to 80 m.
Series 2 — for depths 80–180 m.
Series 3 — for deep borewells up to 300 m.
Sizes Available
1 inch (25 mm) to 4 inch (100 mm) — covering domestic single-phase pumps to heavy agricultural and industrial sets.
Installation Tips
Use only manufacturer-supplied O-rings on every joint.
Tighten couplers with chain wrench, never pipe wrench.
Support the column at the well-head with a clamp before adding the next length.
Frequently Asked Questions
Which IS standard covers PVC column pipes?
IS 12818 covers PVC column pipes for submersible pump applications in India.
What is the maximum depth for PVC column pipes?
Series 3 PVC column pipes are designed for borewells up to 300 m deep.
Can PVC column pipes carry hot water?
No. PVC column pipes are designed for borewell water at ambient temperature only.
