Ultra-thin walls & micro-diameter for precision flow control
Manufactured from premium nickel-based alloys with excellent corrosion & heat resistance
Support customized sizes, lengths, and surface treatments for diverse industry needs
Our nickel alloy capillary tubes are engineered for applications that require micro-diameter precision, excellent corrosion resistance, and stable performance under extreme conditions. Using high-grade nickel-based alloys including Inconel, Monel, Hastelloy, Incoloy, Nickel 200/201, and others, the tubing maintains reliable performance in high-temperature, high-pressure, and chemically aggressive environments.
With advanced drawing, solution treatment, and annealing processes, each capillary tube features uniform wall thickness, smooth inner surfaces, superior flexibility, and high fatigue strength, ensuring stable flow control and accurate signal transmission.
We support custom manufacturing with special tolerances, long-length coils, and optional polishing or pickling surface treatments.
