Seamless Tube/Pipe and Welded Tube/Pipe
UMM 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.
In general, tantalum has excellent corrosion resistance and is often used in chemical processing equipment. To enhance the performance of the metal, UMM recommends using our seamless tantalum 2.5% tungsten tubing.

Tantalum and Tantalum Alloys Seamless Tube and Welded Tube Performance Comparison
Products Specification Advantage Disadvantage Tantalum Seamless Tube/Pipe Usually suitable for the production of small batch but many specifications 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.1)The uniformity of wall thickness is difficult to control.
2)Production leadtime is long and low yield.
3)Complex equipment and large investment.
4)Difficult to produce large diameter tubes.Tantalum Welded Tube/Pipe Usually suitable for the production of small batch but many specifications 1)The wall thickness is even and the inner surface quality is good.
2)High production efficiency and low cost.
3)Easy to produce large diameter tubing.
4)Short production leadtime
5)Easy to ontrol products' quality.1)Poor flexibility, not suitable for production of more specifications but fewer batches.
2)Weld seams are often the weak links.
3)It is difficult to clean the weld seam.
4)The ellipticity is not easy to control.
5)High requirement for the dimension precision of strip.
