Applications of Niobium Capillary Tube / Pipe
Niobium capillary tubes are used for high-pressure sodium lamp production.
Niobium capillary pipe can be used as heat exchange pipe in the heat exchanger; can be used as thermometer protection pipe in the petrochemical industry.
Capillary tubes are used in insulating glass units to equalize the pressure between the sealed panes for the installation of windows at high altitudes.
Medical capillary tubes are used for the centrifugation of blood samples.
Packing of Niobium Capillary Tube / Pipe
Standard Packing:
