Corrosion Resistance

Corrosion Resistance

The ability of a well screen to resist corrosion, electrolysis, and other types of chemical deterioration plays a crucial role in determining the lifespan of a well. The corrosion resistance depends on two main factors: the chemical composition of the formation water and the material used to construct the screen.

The most commonly available materials for well screens include mild steel, stainless steel, red brass, bronze, and various plastics. Each material offers different advantages in terms of durability and cost.

In some limited areas, mild steel screens may perform satisfactorily for many years, providing both low initial cost and long service life. However, practical experience has shown that other materials generally offer superior performance. These alternative materials typically provide longer lifespan, better resistance to various well cleaning agents, and overall more satisfactory performance - although they do come with higher initial installation costs.

The choice between these materials involves careful consideration of the specific water chemistry, expected well lifespan, and budget constraints to determine the most cost-effective solution for each unique situation.
