What Is a uPVC Column Pipe?
A uPVC column pipe is a riser pipe used to connect a submersible pump inside a borewell to the water-delivery point at the surface. It carries pumped water upward while supporting the suspended load of the pump, pipe string, water and connected fittings.
Unlike a normal water-supply pipe, a column pipe must handle both water flow and mechanical load. Therefore, the correct pipe should not be selected by diameter alone. Borewell depth, pump requirement and the load rating of the selected pipe series must also be considered.
In India, users may also refer to these pipes as submersible pipes, borewell column pipes or boring pipes.
Column Pipe vs Casing Pipe
A column pipe and a casing pipe are both used in borewell systems, but they perform different functions.
| Factor | Column Pipe | Casing Pipe |
|---|---|---|
| Main Purpose | Carries pumped water to the surface | Supports and protects the borewell structure |
| Position | Connected to the submersible pump | Installed along the borewell wall |
| Main Load | Pump, water and pipe-string load | External soil and formation pressure |
| Pump Servicing | Removed with the pump system when required | Normally remains installed |

How to Choose the Right Column Pipe for Your Borewell
The right column pipe should be selected according to the complete borewell and pumping requirement, not only the pipe diameter.
1. Check the Required Pipe Size
Confirm the required delivery-pipe diameter from the submersible pump specification or system design.
Pump horsepower alone should not be used to select the pipe size because outlet sizes may vary between different pump models.
2. Check the Pump Installation Depth
Use the actual depth at which the submersible pump will be installed when comparing column-pipe ratings.
The total borewell depth and actual pump-setting depth may not always be the same.
3. Consider the Suspended Load
A column-pipe assembly must support the combined effect of:
- Submersible pump weight
- Water inside the pipe
- Pipe-string weight
- Connected fittings and components
- Installation and servicing loads
4. Select the Appropriate Series
Duke provides multiple column-pipe series for different load and depth requirements.
A heavier-duty series is not automatically required for every borewell. The selected pipe should match the actual application and technical requirement.
5. Check the Safe Installation Depth
Always compare the required pump-setting depth with the safe installation depth specified for the exact pipe size and series.
Do not use the highest depth shown in the range as the rating for every Duke column pipe.

What Is a uPVC Column Pipe?
A uPVC column pipe is a riser pipe used to connect a submersible pump inside a borewell to the water-delivery point at the surface. It carries pumped water upward while supporting the suspended load of the pump, pipe string, water and connected fittings.
Unlike a normal water-supply pipe, a column pipe must handle both water flow and mechanical load. Therefore, the correct pipe should not be selected by diameter alone. Borewell depth, pump requirement and the load rating of the selected pipe series must also be considered.
In India, users may also refer to these pipes as submersible pipes, borewell column pipes or boring pipes.
Column Pipe vs Casing Pipe
A column pipe and a casing pipe are both used in borewell systems, but they perform different functions.
| Factor | Column Pipe | Casing Pipe |
|---|---|---|
| Main Purpose | Carries pumped water to the surface | Supports and protects the borewell structure |
| Position | Connected to the submersible pump | Installed along the borewell wall |
| Main Load | Pump, water and pipe-string load | External soil and formation pressure |
| Pump Servicing | Removed with the pump system when required | Normally remains installed |
For borewell protection, explore Duke uPVC Casing Pipes.
uPVC Column Pipe Price in India
The uPVC column pipe price depends on the pipe diameter, series, load class, quantity and delivery location.
Different series within the same pipe size have different technical specifications and load capacities, so pricing can vary between Nano, Medium, Standard, Heavy, Super Heavy and other applicable variants.
Duke column pipes are supplied in approximately 10-ft lengths. For the latest price, share:

How to Choose the Right Column Pipe for Your Borewell
The right column pipe should be selected according to the complete borewell and pumping requirement, not only the pipe diameter.
1. Check the Required Pipe Size
Confirm the required delivery-pipe diameter from the submersible pump specification or system design.
Pump horsepower alone should not be used to select the pipe size because outlet sizes may vary between different pump models.
2. Check the Pump Installation Depth
Use the actual depth at which the submersible pump will be installed when comparing column-pipe ratings.
The total borewell depth and actual pump-setting depth may not always be the same.
3. Consider the Suspended Load
A column-pipe assembly must support the combined effect of:
- Submersible pump weight
- Water inside the pipe
- Pipe-string weight
- Connected fittings and components
- Installation and servicing loads
4. Select the Appropriate Series
Duke provides multiple column-pipe series for different load and depth requirements.
A heavier-duty series is not automatically required for every borewell. The selected pipe should match the actual application and technical requirement.
5. Check the Safe Installation Depth
Always compare the required pump-setting depth with the safe installation depth specified for the exact pipe size and series.
Do not use the highest depth shown in the range as the rating for every Duke column pipe.
Duke Column Pipe Size & Safe Depth Guide
The following table gives a simplified overview of the main Duke series. Exact ratings should be confirmed from the complete technical table for the selected product.

FAQs
What is a uPVC column pipe?
A uPVC column pipe is a riser pipe that carries water from a submersible pump inside a borewell to the surface. It also supports the combined weight of the pump, pipe string and water.
What is the length of a Duke column pipe?
Each Duke column pipe is approximately 3 m (10 ft) long. Exact length varies slightly by size and series, from about 3,010 mm to 3,120 mm, so prices are quoted per 10-ft pipe.
What is the price of a 10 feet column pipe?
The price depends on pipe diameter, series, quantity and delivery location. For today’s rate, send your size, series and pincode on WhatsApp at +91 73920 73920.
Which column pipe is best for my borewell?
The best pipe is one whose size matches your pump outlet and whose safe installation depth is higher than your pump-setting depth. A heavier series is not always needed; use the size and depth guide above.
How do I choose the right column pipe for my submersible pump?
First match the pipe diameter to your pump’s delivery outlet, then pick the series by pump-setting depth. Pump HP alone is not enough because outlet sizes vary by pump model. Ask Duke’s team if unsure.
How deep can a Duke uPVC column pipe be installed?
It depends on size and series. Duke column pipes range from about 25 m for Nano series up to 230 m for selected Super Heavy sizes. Check your exact size and series in the load chart.
What is the difference between Nano, Medium, Standard and Heavy series?
They differ in wall thickness, pressure rating and load capacity. Nano suits shallow borewells, Medium and Standard suit mid-depth borewells, and Heavy to Extra Super Heavy are for deep borewells and heavier pumps.
What is the difference between a column pipe and a casing pipe?
A column pipe carries pumped water to the surface, while a casing pipe supports and protects the borewell wall. Most borewells need both.
Are column pipe, submersible pipe and boring pipe the same?
Yes. “Column pipe” is the technical name, while “submersible pipe”, “boring pipe” and “borewell column pipe” are common names for the same product in different parts of India.
Is uPVC column pipe better than GI pipe?
For most borewells, uPVC is lighter, does not rust and keeps a smooth inner surface, while GI pipe can corrode and scale over time. Always choose a uPVC series rated for your depth and pump load.
How can I identify a genuine Duke column pipe?
Check the Duke inkjet printing showing size and series, the Duke hallmark, and the series colour code. If any marking is missing, contact Duke Pipes before installation.
Where is Duke Pipes located, and do you deliver across India?
Duke Pipes Private Limited manufactures uPVC column pipes in Palanpur, Gujarat, and has been making uPVC pipes since 1998. Duke supplies across India; call 02742-280023/24 or WhatsApp +91 73920 73920.
