Advantages and Disadvantages of Tantalum Seamless Pipes and Welded Pipes

Advantages

Drawbacks

illustrate

Welded pipe

1: Uniform wall thickness and good inner surface quality
2: High production efficiency and low cost
3: Easy to produce large diameter pipes
4:Short production cycle
5: Product quality is easy to control

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

2: Welding seams are often the weak link

3: Welding seams are difficult to clean

4: Ovality is difficult to control

5: High dimensional accuracy requirements for the strips used

Generally suitable for producing large batches of products

Seamless tube

1: Can produce small-sized pipes and capillary pipes

2: Good flexibility, suitable for producing products with small batches and multiple specifications.

3: The performance of each part of the pipe is uniform

1: The uniformity of wall thickness is difficult to control

2: The production cycle is long and the yield is low

3: The equipment is complex and the investment is large

4: It is difficult to produce large-diameter pipes

Generally suitable for producing products with small batches and large specifications.

Tantalum tube

Tantalum is mainly found in tantalite and is symbiotic with niobium. Tantalum has moderate hardness and is very malleable. It can be drawn into thin foil. Its coefficient of thermal expansion is very small. Tantalum has excellent chemical properties and is highly resistant to corrosion. Can be used to manufacture evaporation vessels, etc., can also be used as electrode, rectifier, electrolytic capacitor of electronic tubes. It is used in medicine to make thin sheets or threads to mend damaged tissue. Although tantalum is highly corrosive, its resistance is due to the formation of a stable protective film of tantalum pentoxide (Ta2O5) on its surface.
Tantalum welded tube and Tantalum seamless pipes:

Tantalum can be used to make tantalum welded tube and tantalum seamless pipes and has a wide range of uses. The manufacture of tantalum seamless tube is by extrusion, pipe reduction or deep drawing from sheet metal. The welding method is to form strips first, then make them into tubes, and then weld the seams with gas tungsten arc (GTAW).

Tantalum Tube (Tantalum Pipe) testing:
Chemical Composition and mechanical property, Ultrasonic testing, Electric non-destructive testing, Hydrostatic testing, Visual surface inspection, Dimensional inspection.
