What are the pros and cons of steel versus PVC for well construction?

Sunday, August 25, 2019

Steel has long been the standard material for well construction, but we are seeing more PVC in the last decade. Here’s the advantages and disadvntages of both:

STEEL

Pro
• Stronger, resistant to collapse.
• Standard, time-tested material.

Con
• More expensive.
• Installation requires more labor.
• Corrosion over time due to galvanic reaction, regular rust, and naturally occurring iron bacteria.
• Corrosion-roughened surfaces provide home for bacterial growth.

PVC

Pro
• Easier installation.
• Less expensive.
• No corrosion.
• Smooth interior surface discourages bacterial attachment and growth.

Con
• Susceptible to extreme temperatures.
• Ultraviolet in sunlight degrades PVC unless protective coating.
• Not as strong, lower resistance to collapse, limiting their use in deep water wells.
