Corrosion Resistant Alloys (CRAs) Solution for Geothermal

Geothermal environments pose extreme challenges, including high temperatures (up to 300°C), corrosive fluids (H₂S, CO₂, chloride, sulfate), and abrasive particles that impact equipment performance and lifespan.

These conditions require materials that can resist corrosive media, thermal stress and wear.

CRA Overlay Solutions for Long-Lasting Geothermal Piping

CRA overlay provides a protective layer on piping, shielding carbon steel surfaces from high-temperature steam and aggressive chemicals like chlorides and sulphides found in geothermal environments.

This overlay extends the longevity of piping by preventing oxidation, stress corrosion cracking, and corrosion, ensuring reliable and durable geothermal steam transport and processing. It can be applied to:

Steam Gathering Flowlines
Reinjection Lines
Geothermal Process Piping
Downhole Production Tubing & Liners
Pre-Fabrication: Spools & Modules

Wear Resistant Hardfacing

Hardfacing solutions for high-wear components, enhancing durability in abrasive environments.

Corrosion-Resistant Clad & Lined Pipes

CRA clad & lined pipes designed to withstand corrosive brines.

Steam Gathering flowlines

Our CRAs Mechanically Lined Pipes, Cladded Pipes and Fittings, offer superior performance for steam flowlines:

Ultimate Performance
CRA layered pipes delivers cost efficiency, reliability, and ease of installation.

Lower CO₂ Emissions:
CRA solutions emit less than 50% of the CO₂ compared to solid CRA.

Geothermal Process Piping

Cost Effective
Clad and lined components offer significant savings compared to solid high-nickel alloys like 625 and C276.

High-Temperature Advantage
Weld overlay (WOL) is often more cost-effective than Duplex and Super Duplex in high-temperature applications, with reduced temperature related derating.

Material Optimisation
Lining allows for optimal material selection, enhancing performance.
