Inconel 600 Capillary Tube Supplier

As a leading Chinese manufacturer of high-temperature alloys, our Inconel 600 capillary tubes offer stable and durable performance in aerospace, nuclear power, petrochemical, and heat treatment equipment industries
The thermal fatigue resistance of Inconel 600 capillary tubes makes them particularly suitable for manufacturing core components such as thermocouple protection tubes, high-temperature sensor sheaths, and burner nozzles, ensuring accurate signal transmission and media flow even under intense heat and flame
The value of capillary tubes lies in their small diameter and uniform wall thickness, while the value of Inconel 600 lies in its high-temperature strength. This combination places extremely high demands on manufacturing precision. Therefore, during production, we employ high-precision cold rolling and drawing processes to strictly control the outer diameter, inner diameter, and wall thickness of the tubes. We can lock tolerances within an extremely small range, ensuring that every meter of capillary tube has a highly consistent flow cross-sectional area and mechanical properties, achieving seamless connection and stable output whether used for pressure tapping in precision instruments or as heating element sheaths.

Chemical Composition of Inconel 600

*Chemical Composition According to ASTM B167 / ASTM B516

Inconel 600 alloy is a nickel-chromium-iron-based solid solution strengthened superalloy whose core advantage lies in its exceptional adaptability to high-temperature environments. In oxidizing atmospheres exceeding 1000 degrees Celsius, this material forms a dense and highly adhesive chromium oxide protective film on its surface, effectively preventing further oxidation and corrosion of the substrate. Whether subjected to repeated thermal shocks from temperature fluctuations or under long-term stable insulation conditions, it maintains structural integrity and dimensional stability.
