Titanium U tubes for heat exchangers are widely used in all kinds of seafood farming, sea water heat exchange, salt water exchange, chemical industry, food, medicine, metallurgy, refigeration, light industry, electroplating industry, aluminum oxidation tank, salt making, paper, ultrasonic, electronic communication, central heating and other industries and fields.
Titanium U tubes are used as the medium to transform nature water, sea water, salt water or other corrosive solution.
Titanium U tubes together with solid titanium tubesheets and titanium shell make up of a heat exchangers. And it is as popular as titanium tubes and titanium bars.
