Tantalum Seamless Tube
Raytec metal provides our customers superior tantalum and tantalum alloy seamless tubes. Less likely to fail than typical welded tubing, our process starts by piercing large diameter billets and forging the tubes down to your required dimensions. This eliminates weak spots in the products that could fail due to cracking, holes or tearing. Additional we can perform an eddy current test to detect leaks and pressure test the tubes to ensure there are no leaks.
Advantages of seamless tube
1) Can produce small specification tube and capillary tube
2) Good flexibility, suitable for production of small batch but many specifications
3) The performance of the whole tube is homogeneous
In general, tantalum has excellent corrosion resistance and is often used in chemical processing equipment. To enhance the performance of the metal, Raytec metal recommends using our seamless tantalum 2.5% tungsten tubing. A wide variety of diameters and wall thicknesses are available. The typical specification is ASTM B521 R05200 for pure tantalum and ASTM B521 R05252 for tantalum 2.5% tungsten.
