Why Titanium for Heat Exchangers
Heat exchangers in seawater cooling, chemical processing, and desalination service face aggressive corrosion that limits the service life of conventional materials. Copper-nickel tubes pit and erode in high-velocity or polluted seawater. Stainless steel tube sheets suffer crevice corrosion at tube-to-tubesheet joints. Titanium eliminates these failure modes entirely—providing complete immunity to seawater corrosion, resistance to most process-side chemicals, and service lives measured in decades rather than years. The result is lower total cost of ownership through reduced replacement frequency, maintenance downtime, and inspection costs.
Components We Manufacture
CastAlloy produces titanium heat exchanger components including forged tube sheets in CP Grade 2 and Ti-6Al-4V for high-pressure applications, channel heads and bonnet covers, baffle plates and tie rods, shell flanges and nozzle forgings, and expansion joint components. Our forging capabilities produce tube sheets up to several hundred kilograms with the refined grain structure that resists stress corrosion cracking at weld joints. Precision CNC machining achieves the tube hole patterns, gasket surfaces, and bolt hole patterns required for TEMA and ASME compliance.
Standards Compliance
Titanium heat exchanger components are manufactured per ASME Boiler and Pressure Vessel Code Section VIII, TEMA standards for shell-and-tube heat exchangers, and customer specifications. Material is procured per ASTM B265 (plate), ASTM B381 (forgings), or ASTM B348 (bars) with full mill certifications. Contact CastAlloy for heat exchanger component quotations.
