Titanium Tubes for Tubular Heat Exchangers
A titanium heat exchanger is a heat-transfer device, made of titanium or its alloys, that is used for transfer of internal thermal energy between two or more corrosive fluids. Titanium tubes manufactured to ASTM B338/ ASME SB-338 are widely applied for the fabrication of tubular heat exchangers. The tubular heat exchanger mainly covers double-pipe heat exchanger, shell and tube heat exchanger, and coiled tube heat exchanger. The titanium tubes can be furnished in either seamless or welded style.
