Electropolished Tubing in Long Continuous Coils

O’Brien Analytical TrueTube EP is electropolished select grade 316L SS tubing. Electropolishing not only improves surface roughness but also enhances the corrosion resistance by leaving a chromium enriched surface layer. Our proprietary process has broken the twenty-foot straight stick limit for electropolished tubing. We provide a consistent electropolished surface on tubes up to 300 feet / 100 meters long - ideal for use in critical analyzer systems.

O’Brien Analytical’s unyielding commitment to quality is evident in every step of our manufacturing process. TrueTube EP is inspected by O’Brien’s highly trained inspectors, and produced in accordance with an ISO 9001 registered quality system. All TrueTube EP is inspected, cleaned, packaged and always delivered on-time to you.
