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.
