Tantalum Tube / Pipe

tantalum tube

Tantalum Tube / Pipe processing technology and characteristics

There are two methods to process Tantalum Tube / Pipe: one is to produce seamless tube by extruding tube blank, and the other is to produce welded tube by drawing process after inert gas Tungsten arc welding.

Applications of Tantalum Tube / Pipe

Tantalum and Tantalum alloy tubes / pipes are commonly used in chemical industry, atomic energy and aerospace field.
Tantalum and Tantalum alloy tube / pipe (such as Ta-2.5W Tube, Ta-10W Tube, Ta-40Nb Tube, etc.) are more resistant to high temperature and mineral acid corrosion than many other materials. Tantalum and Tantalum alloy tubes are mainly used to manufacture reaction vessels, heat exchangers, pipes and thermocouple pipes for chemical processes.

Advantages and disadvantages of Tantalum Seamless Tube and Welded Tube

  Advantage Disadvantage Description
Welded Tube 1.The wall thickness is uniform, and the inner surface quality is excellent
2.High production efficiency and low cost
3.Easy to produce large diameter tube
4.Product quality is easy to control
1.Flexibility is poor, not suitable for producing variety specifications and small batch products
2.Welds are often the weak links
3.Weld cleaning is difficult
4.Ovality is not easy to control
5.High precision is required for the used strip size
Generally suitable for large-scale production
Seamless Tube 1.Can produce small size tube and capillary tube
2.Flexibility, suitable for small-scale production, more specifications
3.All parts of the tube have uniform performance
1.The uniformity of the wall thickness is difficult to control
2.Long production cycle and low yield
3.Complex equipment and large investment
4.Difficult to produce large diameter pipes
Generally suitable for the production of small quantities of many specifications of products
