3. 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, condensator, clip heater, helix loop, U-pipe in the chemical courses, thermocouple and its protective pipe, liquid state metal container and pipe.

 

4. Advantage of our Ta tube


-polised surface with high quality.    
- uniform grain with densified microstructure ensures longer use time.
- precise machining tolerance.

-professional after-sales service
