Stainless Steel Pipes for Geothermal Energy Systems: Scaling and Corrosion Control

Geothermal energy plants use stainless steel piping for steam transport and reinjection wells, requiring resistance to extreme temperatures and aggressive geothermal fluids.

• Scaling Prevention: Electropolishing and hydrophobic coatings reduce mineral scale deposition from high-salinity geothermal brine.
• Resistance to Acidic Gases (CO₂, H₂S): Duplex stainless steels (2205, 2507) outperform 316L in high-CO₂ geothermal wells by reducing corrosion rates.
• High-Temperature Stability: 347 stainless steel, stabilized with niobium, resists carbide precipitation in superheated steam applications.
