Tantalum Tube, Tantalum Pipe
Tantalum tubes are cylindrical tubes made of tantalum metal, which is a rare, blue-gray, dense, and ductile element. Tantalum tubes possess excellent corrosion resistance, high melting point, and good thermal conductivity, making them ideal for use in chemical processing equipment, heat exchangers, and furnace components. Tantalum tubes can withstand extreme temperatures and are highly resistant to chemical attack by acids and other corrosive substances. Tantalum tubes are available in various sizes, wall thicknesses, and lengths to meet specific application requirements.
