Tantalum Tube

  • Tantalum tube
  • Tantalum pipe

Product Details

Tantalum Tube Products Standard

Our pure tantalum tube (UNS R05200), Ta 2.5W tube (UNS R05252), Ta 10W tube (UNS R05255) and Ta 40Nb tube (UNS R05240) meet ASTM B521 standard and can be custom designed based on your drawing and request.

Tantalum Tube Production Technology

  • Ta can be made into welded tube and seamless tube which are all widely used in industry. Seamless tube is made by extruding, tube shrinkaging or plate deep drawing. Welded tube is made by forming strips, shaping into tubes, and welding the seam with GTAW.

Tantalum and Tantalum Alloys Welded Tube and Seamless Tube Performance Comparison
　 Advantage Disadvantage Specification
Welded Tube 1)The wall thickness is even and the inner surface quality is good. 1)Poor flexibility, not suitable for production of more specifications but fewer batches Usually suitable for the production of large batches
2)High production efficiency and low cost 2)Weld seams are often the weak links
3)Easy to produce large diameter tubing 3)It is difficult to clean the weld seam
4)Short production leadtime 4)The ellipticity is not easy to control
5)Easy to ontrol products' quality 5)High requirement for the dimension precision of strip
Seamless Tube 1)Can produce small specification tube and capillary tube 1)The uniformity of wall thickness is difficult to control Usually suitable for the production of small batch but many specifications
2)Good flexibility, suitable for production of small batch but many specifications 2)Production leadtime is long and low yield
3)The performance of the whole tube is homogeneous 3)Complex equipment and large investment
　 4)Difficult to produce large diameter tubes

Tantalum Tube Application

Tantalum is mainly used in corrosion resistant and superconducting industries. It can be made into corrosion resistant nozzles or electrode tubes. Tantalum is also widely used in the manufacture of chemical products such as reaction containers, pipes, condensers, bayonet heater and heat exchangers, spiral coil, U tubes, thermocouple protection tubes, and the liquid metal containers and pipes, etc.
