In well construction, what material is commonly used for casing?

In well construction, steel or PVC is commonly used for casing due to their favorable properties. Steel casing is particularly valued for its strength and durability, which provides structural integrity to the well and protects it from collapse under external pressures. It can withstand harsh environmental conditions and is resistant to corrosion, especially when protective coatings are applied.

PVC casing is also popular, particularly for applications where corrosion resistance and lightweight characteristics are essential. PVC is non-corrosive and relatively easy to install, making it suitable for many types of wells, especially in environments where metal may deteriorate faster.

Both materials are designed to safely contain well fluids and protect groundwater from contamination, making them ideal choices for effective well casing. Choosing these materials helps ensure the longevity and reliability of the well infrastructure.
