ASTM A270 Welded High Purity Stainless Steel Tubing TP316L Smooth Surface
ASTM A270 Welded & Polished High Purity Stainless Steel Tubing TP316L 1'' X 0.065'' X 20FT
Specifications:
Spezilla 's high purity BPE 316L stainless steel tubing is manufactured exceeds the requirements of ASME-BPE SF1 and ASTM A270 S2. All tubing is 100% boroscoped and certified to 20 μ-in Ra (0.5 μm) inner diameter (ID) maximum, and 30 μ-in Ra (0.8 μm) outer diameter (OD) maximum surface roughness. Surface finishes are measured per ASME/ANSI B46.1, with the profilometer reading at 90 degrees to major polishing pattern.
Mechanical Tests
To ensure the highest surface quality in all of our sanitary tubing, Spezilla goes beyond the requirements of ASTM A269 and A270 by performing the full battery of ASTM bend and deformation tests required by ASME SA249 . The tests, combined with specific raw material requirements, Eddy Current testing at the tube mill, 100% boroscoping prior to mechanical polish, and tighter OD and wall tolerances, allow to provide a more consistent, superior quality product.
