Cleaning
Most A270-BPE high purity tubing is available from stock with ID cleaned for oxygen service. Other ID
cleaning procedures are available including thermocouple cleaning per ASTM A632 or Nitric Acid &
deionized water rinse. The de-ionized water system guarantees less than 50 ppb TOC with an average
of 10 ppb and a resistivity up to 18 M. They also utilize 99.9999% pure Nitrogen which is filtered to 0.003
µm at the point of use. Cleaning and packaging are performed in a certified Class 100 Cleanroom.

Surface Finish
Surface finish is 20 µ-in Ra (0.5 µm) ID maximum, 30 µ-in Ra (0.8 µm) OD maximum measured per
ASME/ANSI B46.1 with the profilometer reading at 90 degrees to major polishing pattern.

Packaging
As a final step in maintaining purity standards following cleaning, our A270-BPE tubing is packaged
using protective 6 mil poly sleeving along with air tight plastic end caps. The tubing is then placed in
wood boxes for maximum protection during shipment. Other packaging is available on customer request.
