Tantalum cannot be processed by ordinary methods for processing general metals. Generally, the initial process is forging and heat treatment, and flat billets or round and small billets are made by hammering and stamping.

Tantalum tube manufacturing characteristics

Tantalum can be made into welded tubes and seamless tubes, which have a wide range of uses. Seamless tubes are made by extrusion, tube reduction or deep drawing of plates. The welding manufacturing method is to form the plate strip first, then make it into a tube shape, and then weld the seam with gas tungsten arc (GTAW).

Advantages and disadvantages of tantalum seamless tubes and welded tubes

Advantages of welded tubes

1: Uniform wall thickness and good inner surface quality

2: High production efficiency. Low cost

3: Easy to produce large diameter pipes

4: Short production cycle

5: Easy to control product quality

Disadvantages of welded tubes

1: Poor flexibility, not suitable for producing products with many specifications and small batches

2: Welds are often weak links

3: Weld cleaning is difficult

4: Ovality is not easy to control

5: High requirements for the size accuracy of the strip used

Generally, welded tubes are suitable for producing large batches of products

Advantages of tantalum seamless tubes

1: Can produce small-sized pipes and capillary pipes

2: Good flexibility, suitable for producing small batches and many specifications of products.

3: Uniform performance of each part of the pipe

Disadvantages of tantalum seamless tubes

1: Difficult to control the uniformity of wall thickness

2: Long production cycle, low yield rate

3: Complex equipment, large investment

4: Difficult to produce large diameter pipes

Generally, Seamless tubes are suitable for producing small batches of products with many specifications
