Designed for critical and purity applications such as semiconductor manufacturing, LSI's high purity tubing delivery of gases, chemicals and solvents, or use in ultra High vacuum piping for reducing out gas rate. From advanced manufacturing processes, including special cold drawing and cold pilgering, not just precision for sizes, but also enhance material substrutes density by cold pilgering process. The ID is cold rolling to a 15Ra(0.4μm) finished, by Hydrogen bright annealed process removed tube lubrication and optimum anti-corrosion ability, stress free, good mechanical properties follow by precision cleaning process to removed any residual contaminants, simulated natural light inspection at both ends verifies cleaning before the tubes are nitrogen purged and capped.
Surface Treatment: Bright annealed, polished outside and inside surface,Electronic Polishing.
