2.Advantages and disadvantages of seamless tantalum tube and welded tube:


  Advantage Disadvantage Mark
Welding tube


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: Product quality is easy to control



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

2: Welds are often the weak link

3: Weld seam cleaning is difficult

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: Long production cycle and low yield

3: Complex equipment and large investment

4: Difficult to produce large diameter pipes


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