Pure Tantalum tube manufacturing features

Tantalum can be made into welded tubes and seamless tubes, and has a wide range of uses. Seamless tubes are made by extrusion, tube reduction or deep drawing of plates. The welding manufacturing method is to first form the plate strip, then make it into a tube shape, and then weld the seam with gas tungsten arc (GTAW).

Application Advantages

• Chemical reaction vessels and heat exchangers, pipes, condensers, bayonet heaters, helical coils, U-tubes.

• Thermocouple and its protection tube.

• Liquid metal containers and pipes, etc.

• Tantalum tube for cutting the tantalum ring for jewelry field.
