Tantalum Tube/Tantalum Pipe Seamless/Ta Capillary
Description
Tantalum is excellent in fochemical resistance, and tantalum metal tubes are ideal material for chemical process equipment.
Tantalum can be manufactured into welded tubing and seamless tubing, which are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry.
We produce RO5200, RO5400 with different dimensions of the tantalum semless tubes. Our tantalum welded tubes offer significantly better wall thickness and concentricity control compared to seamless tubes. wall thicknesses are specified to be as thin as structural conditions will permit.
