A titanium heat exchanger is a heat-transfer device, made of titanium or its alloys, that is used for the transfer of internal thermal energy between two or more corrosive fluids. Titanium Heat Exchanger U Tube manufactured to ASTM B338/ ASME SB-338 are widely applied for the fabrication of tubular heat exchangers. Titanium has the super strong corrosion resistant ability. The Titanium heat exchangers use seamless pure titanium tubes as heat conductor, which can be used for a long time thus are cost-saving for after-sale services.
