How to Choose UPVC Well Pipes

Understanding well requirements, regional climate conditions, and long-term objectives should be considered when selecting PVC well casing pipes for a specific application.

Factors to consider when choosing a UPVC well pipe include:

• Pipe Diameter and Depth

  For boreholes, 2-inch UPVC well pipes are commonly used. They are suitable for shallow wells and small water demands. A 3-inch UPVC well pipe is used for moderate-depth wells and increased water needs. They provide improved water flow and are suitable for small to medium-sized pumping equipment. A 4-inch UPVC well pipe is ideal for medium-depth wells and further increased water demands. They allow for higher discharge rates and are compatible with various submersible pump models. Larger diameter pipes are used for greater depth wells and maximum water demand. They ensure optimal flow rates and are suitable for large-scale agricultural or municipal use.

• Water Quality and Contaminants

  Chemical properties of the water should be established to assist in determining the appropriate pipe material. If the water is acidic, it would corrode the metallic pipes, and UPVC pipes would be a better option. Well water may contain sediments, and a larger diameter pipe may be required to accommodate the submersible pump that filters out the sediments.

• Climate and Environmental Conditions

  Consider the temperature range in the area. Extreme hot or cold temperatures may affect the performance of some pipe materials. UPVC pipes are preferred in areas with high corrosion potential in the soil due to their durability and resistance to chemicals.

• Flow Rate and Yield

  A hydrological study can help determine the yield of the well. This affects the choice of pipe diameter and design to ensure optimal flow. Consider the pumping rate. Higher pumping rates may require larger diameter pipes to prevent flow restrictions and ensure efficient water extraction.

• Installation and Maintenance

  UPVC pipes are generally easier to install due to their lightweight nature and simple joining methods. Consider the long-term maintenance requirements. UPVC pipes require minimal maintenance due to their smooth interior surfaces, which help prevent sediment buildup.

upvc well pipes Q & A

Q1: Can you join UPVC pipes with welding?

A1: No, you cannot weld UPVC pipes because they are plastic. The only way to join them is through solvent cementing. In this process, a specific solvent cement is used to soften the pipe ends and fittings temporarily, creating a chemically fused joint when the cement hardens.

Q2: How does one maintain UPVC pipes?

A2: UPVC pipes are low-maintenance. They only need to be cleaned periodically to remove any accumulated dirt. They also need inspection to ensure there are no cracks or signs of damage. In case they are damaged, a trained technician can use solvent cement to repair the damaged section or fitting.

Q3: Are UPVC pipes suitable for hot water?

A3: UPVC pipes are not recommended for hot water applications. This is because they have a low-temperature resistance and can soften or lose structural integrity when exposed to high temperatures. Therefore, for hot water applications, customers can opt for CPVC pipes, a modified version of UPVC better suited for hot water.
