8 Application:Tantalum and tantalum alloy(Ta-2.5W,Ta-10W,Ta-40Nb) tubes have the
advantages,such as high melting point, corrosion-resistant,
facilely-processed in cold environment. They 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-pipe in the chemical courses,
thermocouple and its protective pipe, liquid state metal container
and pipe.
