Electropolished Stainless Steel Tubing |
|
High Purity Tubing for pharmaceutical, semiconductor,
biotechnology, and other processes requiring finishes to 15
μ-in Ra ID maximum.
RathGibson’s True15™ tubing is manufactured to ASME BPE and
ASTM A270 S2 standards, making it ideal for ultra high
purity applications. By utilizing RathGibson’s Micro-Weld™
technology and proprietary electropolishing process, ID
surface anomalies are minimized, providing an ultra-smooth,
corrosion resistant, chromium enriched surface where
contaminants cannot hide. This electropolished tubing is
processed and packaged in a certified ISO Class 5 Cleanroom
(Fed 209E), a must for manufacturing tubing intended for use
in today’s ultra high purity environments. Sizes available
are 1/2" (12.7 mm) to 6" (152.4 mm) OD in stock 20' (6.1 m)
lengths. |

To ensure the highest surface quality in all of our sanitary
tubing, RathGibson goes beyond the requirements of ASTM A269
and A270 by performing the full battery of ASTM bend and
deformation tests required by ASME SA249 as well as
additional deformation tests developed by RathGibson. The
tests, combined with specific raw material requirements,
Eddy Current testing at the tube mill, 100% bore-scoping
prior to mechanical polish, and tighter OD and wall
tolerances allow RathGibson to provide a more consistent
superior quality product.
Hydrogen bright annealed in line to 1900°F (1040°C) minimum
and rapidly quenched.
Surface finish is 15 μ-in Ra (0.4 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.
As a final step in maintaining clean standards, RathGibson
electropolished tubing is packaged using protective 6 mil
poly sleeving along with air tight plastic end caps over a
polyamide patch. The tubing is then placed in wood boxes for
maximum protection during shipment.
