Stainless Steel Capillary Pipe
advatages of Stainless Steel Capillary Pipe
- Stainless Steel Capillary Pipe is manufactured to precise dimensions and tight tolerances, ensuring accurate and consistent fluid flow, which is critical for medical instruments, sensors, and control systems.
- Made from 304, 316, or 316L stainless steel, it offers excellent corrosion resistance and is suitable for chemical, pharmaceutical, and marine applications.
- The tubing is internally polished or brightly annealed to create a smooth interior surface, reducing flow resistance and contamination risk, making it ideal for analytical instruments, microfluidics, and chromatography systems.
Applications of Stainless Steel Capillary Pipe
- Medical and Pharmaceutical Industries: Hypodermic needles and catheters, endoscopes and diagnostic instruments, intravenous infusion systems, and laboratory equipment.
- Analytical and Laboratory Equipment: Gas chromatography and liquid chromatography tubing, capillary columns, microfluidic systems, sampling and injection systems.
- Chemical and Petrochemical Industries: Instrument tubing for pressure, temperature, and flow sensors, valves, and control lines for analyzers.
- Industrial Automation and Instrumentation: Pressure transmitters, valves, and actuators.
Chemical Composition

Possible Alternative Grades
- Nickel alloys (e.g., Inconel 625, Monel 400): For extreme corrosion or high-temperature applications
- Titanium Grade 2 or 5: Lightweight and highly corrosion-resistant
- Carbon steel capillary tubes: Lower cost but not corrosion resistant
- Duplex stainless steels (e.g., 2205): Higher strength and corrosion resistance for harsh environments
Packaging
Once the pipes have passed all inspections and tests, they are ready for packaging. They are usually packaged in bales wrapped in plastic. The pipes can be bundled and ready for delivery according to customer requirements, ensuring that the pipes are protected during transportation and prevent surface damage.
