Sanitary Stain Polished High Purity Stainless Steel Tubing
Manufactured to stringent ASME BPE and ASTM A270 S2 specifications, this high quality tubing is 100% bore-scoped and mechanically polished on both the ID and OD. Finishing processes guarantee specific ID and OD Ra values for customers application, minimizing surface anomalies. Moreover, all A270-BPE series tubing is cleaned in a Class 100 Cleanroom (Fed 209E), significantly reducing customer inspection requirements prior to installation. The finest quality stainless steel materials are made to melt criteria and formed by the manufacturering processes to assure highest weld seam integrity, to meet the most demanding applications. Our tubing is available in 1/2\" (12.7 mm) to 6\" (152.40 mm) OD in 20ft. (6.1 m) lengths.
Specification (link)
Tubing shall be manufactured to A270-BPE 316L meeting or exceeding the requirements of ASME BPE and ASTM A270 S2. All tubing will be 100% bore-scoped and mechanically polished to 20 µ-in Ra (0.5 µm) ID maximum and 30 µ-in Ra (0.8 µm) OD maximum surface roughness measured per ASME/ANSI B46.1 with the profilometer reading at 90 degrees to major polishing pattern, with ends prepared for orbital welding and the tube ID cleaned for oxygen service.
Materials
316L available from stock. 6-MOLY and other alloys available on request.
Mechanical Tests
To ensure the highest surface quality in all of our sanitary tubing, manufacturers routinely go 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 the manufacturers. 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 us to provide a more consistent superior quality product to the marketplace.
Annealing
Hydrogen bright annealed in line to 1900°F (1040°C) minimum and rapidly quenched.
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.
