Tantalum can be manufactured into welded tubing and seamless tubing, which are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry.


Towin Rare Metals manufacture RO5200, RO5400 with different dimensions of the tantalum seamless tubes or pipes. The appearance of tantalum tube wall should be smooth, clean, greaseless, without fissure or burr, no no oxidation or hydrogenation, no scratch or transformation. Tantalum tube and tantalum alloy tube is featured for its high smelting point, super anti corrosion and excellent ductility properties, they are mainly used for manufacturing reaction vessels, heat exchanger pipes, condensers, bayonet heaters, helical coils, thermocouple and protective tubes, electric light source, capacitor, electronic industry.


The process of Seamless Tube/Pipe is fit for customized production. the advantages of welded tantalum tube are listed as below:

  • Available to produce small specification tubes/pipes and capillary tube/pipe
  • Excellent flexibility, available to produce various of specifications but small quantity products
  • Uniform performance of the whole tube/pipe
