What is Electropolishing?

On-Site and Shop Electropolishing

In addition to Astro Pak’s heritage in offering Passivation, Derouging and High-Purity & Precision Cleaning services for critical water and product systems – Astro Pak offers Electropolishing.

Astro Pak’s Electropolishing service provides optimal Ra (Roughness Average) finishes to your equipment, vessels, tanks and systems. The result is a microscopically flat, smooth and featureless surface which helps to enhance cleanability and appearance of stainless steel components, hardware and parts. Expert Polishing technicians will prepare the surface area for our Electropolishing process. The result is that we will meet or exceed the original specified finish, and match or eliminate existing grain.

The ability to Electropolish on-site enables us to repair, maintain or upgrade the required surface finish on the interior of production vessels and their associated equipment with minimal downtime. Our mobilization resources make immediate response possible to ensure timely remediation of vessels large or small, which may have been compromised by chemical attack or mechanical impact.

Let our experts resolve your surface treatment needs. As leaders in numerous market segments that require High Purity and Critical Precision Cleaning, several of our employees sit on committees and boards in such organizations as ISPE, ASME/BPE and others.

What is Electropolishing is a reverse plating process. Parts are fixtured onto a special rack or basket and then lowered into a specifically blended chemical bath. Electrical current is then applied to the part. Instead of adding to the surface imperfections such as impurities, burrs and other defects to be removed. The electropolishing process is monitored and refined to remove metal uniformly to customer specifications allowing great benefits on ultracleaning, microfinishing, and corrosion protection.
