Deliver water. Not rust.
Saurabh Shaktiman uPVC column pipes — IS 12818 certified threaded pipes for submersible pump installation, replacing galvanised steel down to 250 m depth.
The end of corroded column pipes in Indian borewells.
Millions of borewells across India still use galvanised steel column pipes that corrode within years, leach iron into water and require costly extraction and replacement. Saurabh Shaktiman uPVC column pipes eliminate all of that.
Rust-free — permanently
uPVC does not rust, corrode or pit — unlike galvanised steel which degrades inside the bore and contaminates water over time.
Lightweight installation
Column pipes weigh a fraction of GI — faster lowering, less strain on the pump motor cable and easier withdrawal for servicing.
Long operational life
No corrosion means no replacement cycles — column pipes last the operational life of the submersible pump installation.
Smooth inner wall — better flow
Lower surface roughness than GI pipe means less head loss, delivering more water per metre of pump head.
High tensile strength
uPVC column pipes are designed to withstand the tensile loads and pressures encountered during submersible pump operation — rated for installations down to 250 m depth.
UV stabilised
UV stabilisers in the compound protect above-ground sections from sun exposure, preventing embrittlement and colour degradation over the life of the installation.
uPVC vs Galvanised Steel column pipes.
| Property | uPVC (Saurabh Shaktiman) | Galvanised Steel |
|---|---|---|
| Material | Rigid uPVC | Galvanised Iron |
| Corrosion resistance | Fully immune | Corrodes within 5-10 years |
| Weight | Low — easy to handle | Heavy — high installation cost |
| Inner surface | Smooth — low friction loss | Rough — higher head loss |
| Water quality | No metallic contamination | Iron leaching after corrosion |
| Design life | 50 years | 5-10 years before replacement |
| Maintenance | Nil | Periodic replacement required |
