Tantalum Tube

At Admat Inc., we pride ourselves on providing our customers with superior tantalum and tantalum alloy seamless tubes. Unlike typical welded tubing, our seamless tubes are less likely to fail. Our process begins by piercing large diameter billets and forging the tubes down to your required dimensions. This method eliminates weak spots, such as welds that could fail due to cracking, holes from rolling deformities, or tearing. Additionally, we can perform an eddy current test to detect leaks and pressure test the tubes to ensure there are no leaks.

Tantalum is known for its excellent corrosion resistance and is often used in chemical processing equipment. To enhance the performance of the metal, Admat recommends using our seamless tantalum 2.5% tungsten tubing.  Much more information regarding corrosion properties can be found HERE.

We offer a wide variety of diameters and wall thicknesses. The typical specifications are ASTM B521 R05200 for pure tantalum and ASTM B521 R05252 for tantalum 2.5% tungsten.
