Geothermal energy

Geothermal heat from below the Earth’s surface is a natural and renewable source of energy. Found around the globe and available year-round, this largely untapped renewable energy source offers a steady, predictable large-scale power generation.

Geothermal power plants are concentrated in geographical areas with high thermal activity.

Production wells are drilled to various depths. The trend in the industry is to go deeper, for increased efficiency. As temperature and pressure increase, this puts higher demands on the materials used. Corrosive conditions can be severe, with high chloride and H2S contents and low pH, calling for the use of higher alloyed corrosion-resistant materials.

Sandvik has a wide range of alloys suitable for geothermal energy, including duplex stainless steels, high alloyed austenitic stainless steels, and nickel alloys.

Products include production tubing and casing, heat exchanger tubing and coiled tubing for injection lines.

Choosing the right material for equipment components can be difficult if the application requires more than just standard stainless steel. We can help you to select appropriate materials for your geothermal plant, and find solutions for the more critical service conditions and applications.
