Brief: Explore what sets this solution apart in an easy-to-follow presentation. This video showcases the complete processing journey of 304/316L stainless steel capillary tubing, from precision slotting and diameter changing to end capping and flaring operations. Watch as we demonstrate how these multi-operation techniques create sophisticated components for micro-fluidic and instrumentation applications.
Related Product Features:
  • Custom processing of 304 and 316L stainless steel capillary tubing for superior corrosion resistance.
  • Precision slotting and perforation using micro-laser cutting or EDM for complex patterns.
  • Controlled diameter changing through swaging for reduction or expansion for connection features.
  • End capping and sealing via cold forming or welding methods for hermetic integrity.
  • End flaring creates trumpet-shaped openings for easy hose and fitting connections.
  • Electropolishing and passivation ensure smooth internal surfaces and enhanced corrosion resistance.
  • Comprehensive inspection and testing including dimensional verification and leak testing.
  • Suitable for chromatography, medical devices, precision fluid dispensing, and sensor applications.
FAQs:
  • What materials are available for capillary tubing processing?
    We process both 304 stainless steel for general purposes and 316L stainless steel for enhanced corrosion and chemical resistance, both supplied in annealed condition suitable for cold working operations.
  • What types of end forming operations can be performed?
    We offer comprehensive end forming including sealing one end through cold-formed domes or welded caps for hermetic seals, and flaring the opposite end with 37° JIC, 45°, conical, or roll flare types for connection purposes.
  • What quality control measures are implemented?
    Our quality control includes 100% dimensional inspection using micrometers and optical comparators, visual inspection, optional pressure or leak testing, material certification per EN 10204 3.1, and thorough cleaning in controlled environments with comprehensive documentation provided.
  • What are the typical applications for these processed capillary tubes?
    These components are ideal for chromatography instruments, medical device sub-assemblies, precision fluid dispensing systems, sensor probes, thermowells, and industrial lubrication or cooling applications requiring precise flow control and sealing.
