Titanium Tubes for Corrosion-Critical Heat Exchanger Service
Titanium heat exchanger tubes are selected for applications where corrosion resistance, low weight, dimensional reliability and long service life are important.
Commercially pure titanium Grade 2 is widely used for heat exchangers and coolers exposed to seawater or chlorinated seawater. Its protective oxide film provides strong resistance to general corrosion, pitting, crevice corrosion and erosion corrosion in many chloride-containing environments.
The correct titanium grade and tube specification should be selected according to:
Process fluid composition · Chloride concentration · pH · Operating temperature · Design pressure · Flow velocity · Crevice conditions · Galvanic coupling · Cleaning chemicals · Applicable product standard · Inspection requirements
DLSS supports titanium heat exchanger tube projects from specification and material review through tube supply, U-bending, inspection, documentation, packing and delivery.
Titanium is not suitable for every process medium. Applications involving strong reducing acids, fluoride-containing solutions, pure oxygen or anhydrous chlorine require careful material and process review.
Seawater Corrosion Resistance
Material options for seawater and chloride-containing service.
Heat Transfer Performance
Thin-wall titanium tubes can support efficient heat-transfer designs.
Low Material Density
Titanium has significantly lower density than ferrous alloys.
Project Specification Control
Grade, manufacturing route, tube form and testing reviewed before production.
