Rath Stainless Tubing
...is
ideal for applications requiring mechanically polished finishes to
20Ra ID maximum and 30Ra OD maximum surface roughness, this high quality
Rath® tubing meets stringent standards for ID and OD finishes
as measured per ANSI B46.1-1995. Fully tested to ASTM A450 requirements,
all A270-BPE tubing is produced utilizing Rath's exclusive Micro-Weld
process which assures weld seam integrity and finish consistency demanded
in pharmaceutical, biotechnology, and other high purity process. Select
tubing with ends prepared for orbital welding in stock 20ft. lengths,
1 1/2" to 4" OD.

(per Rath standards, ASME SA249, and ASTM A270
/ A249 / A450)
- Reverse bend, flattening, and flange testing
- Eddy current (non-destructive electric) testing
- All material is 100% bore-scoped prior to mechanical
polish
- On request: hydrostatic and other tests
Annealing
- Bright annealed to 1900° F (1040°C)
minimum and rapidly quenched
Cleaning
All Rath® Micro-Weld 20Ra ID maximum 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 & DI Water Rinse. Rath's DI water system
guarantees 50 PPB and a restivity of 17.98 to 18.03.
Rath also utilizes ultra high purity 99.9999% pure
Nitrogen which is filtered to .003 micron at the point of use. Cleaning
and packaging is performed in a Class 100 clean room.
Surface Finish
Surface finish is 20Ra ID maximum (roughness average
in u-inches) measured per ANSI B46.1-1995 with the profilometer reading
at 90 degrees to major polishing pattern.
