Descrition

 

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

The process of welded Tube/Pipe is fit for mass production, the advantages and disadvantages are as below:

 

Advantages:

  • Uniform wall thickness, internal surface is in good quality
  • High production efficiency and low costs
  • Easy to manufacture larger diameter tubes/pipes
  • Short production term
  • Easy to control prodcts quality

 

Disadvantages:

  • Poor flexibility, not available to produce various of specifications but small quantity products
  • Welding seam is hard and require skilled person and easy to cause troubles
  • Difficult to clean the welding line
  • Difficult to control ovality
  • Strict dimension requirements for tantalum strips

Towin Rare Metals produce RO5200, RO5400 with different dimensions of the tantalum tubes. Our tantalum welded tubes offer significantly better wall thickness and concentricity control compared to seamless tubes. wall thicknesses are specified to be as thin as structural conditions will permit.
