Quotes - Engineering - SalesTitanium in Tube-in-Tube Heat Exchangers
Titanium provides exceptional corrosion immunity in tube-in-tube designs. Its stable passive oxide layer resists attack from seawater, chlorine compounds, strong oxidizers, and many inorganic acids, enabling long-term reliability where stainless steels and nickel alloys corrode rapidly.
Key Applications for Titanium
- Seawater cooling: Direct seawater exchangers in offshore, power, and coastal facilities.
- Chlor-alkali: Wet chlorine gas coolers and hypochlorite handling systems.
- Desalination: Brine heaters, multi-stage flash, and reverse osmosis recovery exchangers.
- Chemical processing: Nitric acid, sulfuric acid (dilute), and oxidizing media streams.
- Geothermal & mining: Acidic brine and chloride-rich geothermal fluid exchangers.

The Benefits of Titanium in Tube-in-Tube Heat Exchangers
Titanium enables tube-in-tube exchangers in the most corrosive fluids. Near-total immunity to chloride pitting, crevice corrosion, and seawater attack eliminates corrosion allowance and frequent replacements.
Superior resistance to wet chlorine, sodium hypochlorite, nitric acid, and oxidizing acids extends equipment life dramatically. Low density reduces weight in offshore and mobile applications.
Excellent biofouling resistance in seawater minimizes cleaning needs. Counterflow configuration maximizes efficiency in high-fouling or low-flow services.
Higher upfront cost offset by decades-long service, zero downtime from corrosion, and reduced maintenance. Compatible with standard fabrication techniques when properly handled.
Established in offshore platform seawater coolers, desalination brine systems, chlor-alkali plants, geothermal acid brines, and titanium-grade chemical lines — ensuring maximum reliability and lowest total ownership cost in severe environments.
