Key Benefits

• Strong corrosion resistance against hot geothermal brine, sulfide ions and mixed corrosive components from geothermal wells
• High thermal conductivity to maximize heat transfer efficiency in underground geothermal circulation system
• Excellent flexibility after full annealing, easy layout and bending for buried geothermal coil pipeline
• Long continuous coil reduces on-site welding joints and lowers leakage risk in underground environment
• Stable mechanical property under long-term elevated temperature cyclic working in geothermal fields

Grade Description

Grade2 commercially pure titanium performs reliably in hot brine containing chloride and sulfide. It is a preferred material for geothermal energy heat exchange systems, widely adopted for geothermal power projects in Iceland, Indonesia and Philippines where underground geofluid brings complex corrosive media.

Product Features

This long-length titanium coil tube is processed with full annealing treatment to release internal stress. Pickling removes surface oxide scale. Continuous coil structure simplifies underground installation. Every coil passes eddy current and hydrostatic inspection, stable for long time running in geothermal brine circulation loop.

Industry Applications

• Geothermal power plant: geothermal brine heat exchanger, underground circulation coil tubing
• Geothermal energy recovery system for hot spring projects
• Geothermal field auxiliary piping in Iceland, Indonesia and Philippines

Quality Assurance

Every batch undergoes strict inspection before shipment:

• Full dimension tolerance inspection
• Eddy‑current testing (ET)
• Hydrostatic pressure test
• Chemical composition & mechanical property testing
• Material Test Certificate (MTC) supplied for traceability

FAQ

Q: Can you cut titanium coil tubes according to geothermal construction drawings?
A: Yes. Our engineering team can read geothermal drawings and cut coil tubes into target lengths for underground installation.

Q: Why select titanium coil tube for geothermal brine heat exchanger?
A: Titanium resists hot brine, sulfide and chloride corrosion, long coil reduces welding points and improves service life in geothermal wells.

Q: Can you provide material test certificates for geothermal project bidding?
A: Yes, EN10204 3.1 MTC certificates can be supplied to support geothermal project qualification.
