Featuring high melting point, corrosion-resistance and good machinability in cold environment, tantalum tube, also known as tantalum pipe, is widely applied to produce tantalum response vessel, tantalum heat exchangers (shell & tube heat exchanger), tantalum pipe line (piping or channel), tantalum condenser, tantalum agitator, tantalum cooler, tantalum boiler, tantalum bayonet heaters, tantalum spiral (helical) coil, U-tube heat exchanger or "U" tube bundle heat exchanger.
Application
Tantalum tube can be also applied in fluid material tanks along with other glass-lined containers like tantalum thermocouple safeguard sheaths, tantalum thermo well, tantalum emitter, tantalum sleeve. It is also normally used as tantalum tubular sputtering target for semiconductor industry. Tantalum tube is generally applied as tantalum cathode with Hollow Cathode Discharge (HCD).
Advantages of Tantalum Tube
1. Excellent corrosion resistance
2. High temperature strength
3. Easy to machine
4. Good biocompatibility
