Protect geothermal pipework from aggressive brines, steam and condensate without defaulting to solid alloy throughout. Hydroformed mechanically lined pipe combines a carbon-steel host with a corrosion-resistant alloy liner for a high-integrity solution designed for the complete operating envelope.
Discuss your fluid conditions
Geothermal pipework can face high temperatures, chlorides, dissolved CO₂ and H₂S, low pH, oxygen ingress, solids and repeated thermal cycling.
Proclad MLP places the selected corrosion-resistant alloy at the wetted surface, while a carbon-steel host provides structural strength.
Selected to meet the project design basis, fabrication route and mechanical loads.
Matched to the actual fluid chemistry, temperature and corrosion mechanisms.
Controlled hydraulic expansion creates a close, stable fit along the pipe length.

Materials must be selected for the complete operating envelope: start-up, steady state, shut-down, cleaning, oxygen ingress and upset conditions.
High-enthalpy fluid, steam and thermal cycling
Chlorides, CO₂, H₂S, acidity and dissolved oxygen
Two-phase behaviour, velocity, erosion and solids
Corrosion allowance, inspection and intervention strategy
One corrosion-resistant platform, engineered around each duty point.
Corrosion-resistant transport from the well pad to separation and processing facilities.
A CRA wetted surface for high-temperature fluids containing chlorides, CO₂, H₂S and other corrosive species.
Engineered protection for selected above-ground plant and balance-of-plant pipework.
Long-life corrosion resistance for cooled brine and reinjection networks, subject to chemistry and design review.
Qualification is focused on the conditions that matter: geometry, liner alloy, pressure, temperature, chemistry, joining and acceptance criteria. Proclad can review the duty before finalising the solution.
