As Düzgünler Plastik, which has combined its production experience since with technology and is the first manufacturer and patent holder of plastic column pipes in Turkey, we have prepared this expert guide for you. In this article, we will discuss the essential criteria you need to consider to make the right decision, step by step.

5 Critical Criteria for Selecting the Right PVC Column Pipe

It is impossible to judge the quality of a U-PVC column pipe by its appearance alone. True performance lies in the raw material used in its production, the engineering details, and the manufacturer's experience.

1. Raw Material Quality and Special Formulation

Everything starts with the right raw material. The primary factor that determines a column pipe's resistance to impact, pressure, and chemical effects is the purity and quality of the uPVC (unplasticized PVC) raw material used. Recycled or low-quality materials can cause the pipe to become brittle, crack, and burst under pressure over time. The Düzgünler Plastik Difference: We use only the highest quality, 100% virgin uPVC raw materials in our production. Thanks to the special formulations developed in our R&D center, we provide our pipes with extra impact resistance and a long lifespan.

2. Thread Design, Gasket Technology, and Sealing

The threaded sections where column pipes are joined are the most sensitive points of the system. A thread design that cannot withstand the pump's operating torque, the weight of the water column, and the pressure can lead to serious problems such as stripping, breaking, or leakage. Sealing is essential to prevent pressure loss and maintain pump efficiency. The Düzgünler Plastik Difference: With the responsibility that comes from being the pioneer in this field in Turkey, we have developed the patented square thread technology. This special design provides maximum grip, eliminating the risk of stripping. Combined with our high-quality rubber O-ring gaskets, it guarantees 100% sealing in your system.

3. Wall Thickness, Pressure Class (PN), and Depth Compatibility

Every water well has a different depth and pressure. The wall thickness of the selected column pipe must be directly compatible with the well's depth and the pump's discharge capacity. Using a pipe with a lower pressure class (PN) than required can cause the system to collapse under pressure. The Düzgünler Plastik Difference: We produce column pipes in a wide range of pressure classes (from PN6 to PN25) for various depth and pump requirements. All our products undergo rigorous testing for full compliance and safety at the specified pressure ratings.

4. Manufacturer's Experience and Technological Infrastructure

A product is only as reliable as the company that manufactures it. A manufacturer with many years of industry experience, modern production facilities, and a strong R&D infrastructure can maintain quality standards and offer innovative solutions. The Düzgünler Plastik Difference: Our foundations, laid by Ekrem Düzgün in a 100 m² workshop in , have today transformed into a giant 100,000 m² industrial facility in Konya. The know-how we have acquired on this nearly half-century journey and our technological investments are the greatest assurance behind every column pipe.

5. Quality Control Processes and Certifications

Rigorous quality control tests applied at every stage of production and compliance certificates with national/international standards (TSE, ISO, etc.) are official proof of the product's reliability. These documents guarantee that the product meets the declared technical specifications. The Düzgünler Plastik Difference: All our processes, from raw material entry to final product exit, are audited within the framework of ISO quality management systems. By regularly applying numerous tests such as pressure, impact, and leakage in our laboratories, we offer our customers products that not only meet but exceed the standards.

Borewell casing pipes are essential components in the construction of borewells. They ensure the longevity and efficiency of the borewell, safeguarding it from various external factors. Understanding their importance and selecting the right type can significantly impact the borewell’s performance.

Borewells are crucial for accessing underground water in regions where surface water is scarce. They are extensively used for agricultural, industrial, and domestic purposes. To ensure a borewell functions efficiently, the right casing pipes must be used. Borewell casing pipes not only provide structural support but also prevent contamination and blockages, ensuring a consistent and clean water supply.

Structural Integrity

Borewell casing pipes provide structural integrity to the borewell. They prevent the borehole from collapsing, ensuring a continuous water supply. The pipes act as a lining that stabilizes the walls of the borehole, particularly in loose or collapsing soils. Without proper casing, the borewell can become unstable, leading to potential collapses and interruptions in water extraction.

Contamination Prevention

Casing pipes keep contaminants and debris from entering the borewell, maintaining the quality of the water extracted. They act as a barrier against pollutants, preventing surface contaminants, dirt, and debris from infiltrating the water supply. This is especially important in areas with high levels of surface pollution or where the groundwater is susceptible to contamination.

Enhanced Water Flow

The smooth surface of casing pipes, particularly PVC and stainless steel variants, reduces friction and enhances water flow. This ensures that the borewell operates efficiently, maximizing the yield of water and minimizing the energy required for pumping.

PVC Casing Pipes

PVC casing pipes are lightweight and corrosion-resistant. Their smooth surface reduces friction, enhancing water flow. PVC pipes are also cost-effective and available in various sizes, catering to different borewell depths and diameters. They are ideal for shallow to moderately deep borewells and are widely used in residential and agricultural applications.

Steel Casing Pipes

They are ideal for deeper borewells and areas with unstable soil. Despite being heavier and more expensive, their robustness justifies the investment. Steel pipes can withstand high pressure and are less prone to damage from external forces. They are suitable for deep borewells and industrial applications where high durability is essential.

Stainless Steel Casing Pipes

Stainless steel casing pipes combine the benefits of steel with resistance to rust and corrosion. They are suitable for both domestic and industrial borewells, offering longevity and reliability. Stainless steel pipes are more expensive than PVC and regular steel pipes, but their long-term benefits make them a preferred choice for many. They are highly resistant to corrosion, making them ideal for areas with corrosive groundwater or harsh environmental conditions.

HDPE Casing Pipes

High-Density Polyethylene (HDPE) casing pipes are known for their flexibility and resistance to corrosion. They are suitable for both shallow and deep borewells. HDPE pipes are lightweight, easy to handle, and can be fused together to create a seamless and leak-proof lining. They are an excellent choice for areas with shifting soil or seismic activity due to their flexibility and durability.

Fiberglass Casing Pipes

Fiberglass casing pipes are less common but offer unique advantages. They are lightweight, corrosion-resistant, and non-conductive, making them suitable for specific applications. Fiberglass pipes are often used in areas with highly corrosive groundwater or where electrical conductivity needs to be minimized

Proper Installation

Ensure the casing pipes are installed vertically and securely. Use appropriate joints and fittings to avoid leaks. The installation process should be conducted by experienced professionals to ensure accuracy and stability. Proper alignment and secure connections are crucial to prevent leaks and structural failures.

Use of Centralizers

Centralizers are used to keep the casing pipes centered within the borehole. They ensure even spacing around the pipe, which is essential for the proper functioning of the borewell. Centralizers also prevent the casing pipes from coming into direct contact with the borehole walls, reducing wear and tear.

Grouting

Grouting involves filling the space between the casing pipe and the borehole wall with a sealing material. This process prevents surface water from seeping into the borewell and contaminating the groundwater. Grouting also stabilizes the casing pipe, providing additional support and preventing movement.

Regular Maintenance

Regular maintenance is crucial for the longevity of borewell casing pipes. Inspect the pipes periodically for any signs of corrosion or damage. Clean the borewell to remove any accumulated debris and contaminants. Regular maintenance also involves checking for any leaks or structural issues and addressing them promptly to prevent further damage.

Addressing Corrosion

For steel and stainless steel casing pipes, corrosion can be a significant issue. Regularly inspect for signs of rust or corrosion and take appropriate measures, such as applying anti-corrosion coatings or using sacrificial anodes. This helps extend the lifespan of the casing pipes and ensures consistent performance.

Monitoring Water Quality

Regularly monitor the water quality to detect any changes that may indicate contamination. Installing a water filtration system can help maintain water quality and protect the borewell from pollutants. Regular water quality testing also helps in identifying any potential issues early, allowing for timely intervention.
