Tantalum seamless tube/Tantalum welded tube/Tantalum protective tube
Standard: ASTM B521-98
Brand name: RO5200
Specifications: According to customer requirements
Product introduction:
Tantalum has a melting point of 2996℃ and a density of 16.6 g/cm. Tantalum is widely used in electronics, semiconductor, chemical industry, machinery, aerospace, medical treatment, military industry and other industries due to its high temperature resistance, corrosion resistance, good cold processing and welding performance. With the continuous progress and innovation of science and technology, tantalum will be more and more widely used in various fields.
Tantalum can be used in a wide range of applications in the manufacture of welded and seamless tubes. Seamless tubes are manufactured by extrusion, tube reduction, or deep drawing with sheet metal. The welding is made by forming a strip, then forming a tube, and then welding the joint with a gas tungsten arc (GTAW).
Capillary size: Outer diameter Φ0.2 ~ Φ8mm, wall thickness T0.015 ~ 0.5mm.
Highest accuracy: Outer diameter Φ±0.003mm, wall thickness T±0.005mm, length L±0.05mm.
External view: Under the microscope, the inside and outside surface of the pipe presents a uniform metallic luster, no oxidation, hydrogenation discoloration, scratches, deformation, burr, etc
Welded pipe
Generally suitable for the production of large batch products, the advantages and disadvantages of welded pipes are as follows:
| Advantage | Shortcomings |
1: uniform wall thickness, good inner surface quality 2: high production efficiency, low cost 3: easy to produce large diameter pipe 4: short production cycle 5: easy to control product quality | 1: Poor flexibility, It is not suitable to produce products with many specifications and smallbatches. 2: welds are often weak links. 3: it is difficult to clean up welds 4: ovality is not easy to control 5: high dimensional accuracy requirements for the used strip |
Applications: Tantalum parts processing, semiconductor, high temperature materials, corrosion protection industry, electronic industry, etc
