Difference Between Casing Pipes vs Column Pipes in Borewells

To build a reliable borewell system, the components used are equally as important as the water source itself. For many homeowners and farmers, the terminology can be confusing. Two of the most essential yet frequently misunderstood components when building borewell piping systems are borewell casing pipes and borewell column pipes.

While both are integral to your piping, they serve entirely different purposes. Understanding these differences can help you create a long-lasting, maintenance-free water supply. In this guide, we will discuss the exact roles of the casing pipes and column pipes and their applications in your borewell systems to build a robust system.

What are bore casing pipes?

Bore casing pipes are large-diameter pipes used in the drilling of underground borewells. During the drilling process, these pipes are installed to line the walls of the borehole. Their primary job is to provide structural integrity to the well and prevent it from collapsing inward, especially in areas with loose soil or sandy formations.

Key Roles of Casing Pipes:

Trubore Borewell Casing Pipes are manufactured using high-grade uPVC, making them corrosion-resistant pipes and capable of withstanding the high hydrostatic pressure found deep underground.

• Structural Support: They hold back the earth and rock, ensuring the borewell stays open and functional for decades.
• Contamination Barrier: Casing pipes act as a shield, preventing surface water runoff, debris, and pollutants from entering your clean water source.
• Pump Protection: By maintaining a straight and clear channel, they ensure your submersible pump can be lowered and raised without getting stuck or damaged by falling rocks.

What are borewell column pipes?

A borewell column pipe is often also called the riser pipe or the submersible delivery pipe. It is a specialised pipe used to suspend submersible pumps inside borewells and help transfer the water to the surface. These pipes are typically made from uPVC material to provide strength, durability and corrosion resistance during the process.

Key Roles of Column Pipes:

Trubore column pipes feature a unique circlip lock system and square threads to ensure that the joints never slip, even under the most intense pressure.

• Water Transport: Their sole mission is to transport water under pressure to your overhead tank or irrigation system.
• Load Bearing: These pipes must support the weight of the pump, the water column within the pipe, and their own weight.
• Handling Torque: Every time a pump switches on or off, it generates a jerk or torque. Quality column pipes must handle this vibration without loosening.

Why Choosing the Right Pipe Matters?

Borewell constructions are tricky and require durable piping systems. Compromised pipe quality can lead to intense soil pressure, causing a collapsed well. Similarly, a weak column pipe could snap, leading your expensive submersible pump to sink to the bottom of the borewell.

1. The uPVC Advantage

In the past, GI pipes were common, but they were prone to rust and scaling. Modern borewell systems rely on uPVC because it is

1. Corrosion Resistant: It does not react with the chemicals or minerals in the soil.
2. Smooth Flow: The smooth inner surface of Trubore pipes reduces friction, which means your pump uses less electricity to move water.
3. Lightweight: Easier to transport and install, significantly reducing labour costs.

Why Trust Trubore for Your Borewell?

Trubore has a three-decade legacy of providing sustainable piping solutions in India. Our borewell range is engineered for the toughest conditions:

• Trubore Casing Pipes: Available in various categories like CM, CS, and CD to suit different depths and soil types.
• Trubore Column Pipes: Engineered to reach depths of up to 1450 feet, our pipes use a stainless steel circlip lock to provide an everlasting bond between the pipe and the coupler.
• Leak-Resistant Performance: Our pipes come with specially designed EPDM rubber rings to ensure a leak-resistant flow for a long time.

Conclusion

A borewell is a lifetime investment. While the casing pipe protects the structure of the well, the column pipe ensures your water reaches its destination efficiently. Choosing high-quality pipes from Trubore ensures proper access to your borewell water supply.
