1. Manufacturing Process

Meticulous production techniques are required to form Niobium Capillary Tubes, especially those with the grade UNS R04200 and an outer diameter of 1 mm. These tubes are typically created through a series of specialised drawing processes, ensuring that the tube’s delicate dimensions retain their structural integrity. The procedure often involves carefully heating the niobium and then passing it through precision dies, which progressively reduce the diameter to achieve the targeted 1 mm outer measurement. This method helps maintain uniform wall thickness, a crucial factor in applications that demand high levels of accuracy and reliability.

Non-destructive testing techniques are then employed to detect any flaws or inconsistencies that could compromise the tube’s performance. By ultrasonic and eddy current inspections, manufacturers can verify that each tube meets stringent specifications while preserving niobium’s excellent corrosion resistance and mechanical stability. Once validated, the tubes undergo final cleaning and finishing protocols to remove any residual surface impurities. The end result is a smooth, refined capillary tube tailored for high-end applications where dimensional precision is paramount.
