Tantalum Tube Applications

With the features of high melting point, corrosion-resist, good machinability in a cold environment, tantalum, and tantalum alloy (Ta-2.5W、Ta-10W、Ta-40Nb) tubes are widely applied in the chemical industry, high-temperature technology field, and atomic energy industry to build reaction container, and heat exchanger, pipe, condenser, clip heater, helix loop, U-shape pipe, and thermocouple, and its protective pipe, liquid state metal container, and pipe.
