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. |
