Local electropolishing

Tampon electropolishing

Typically, the galvanic process of electrochemical polishing takes place in an electrolyte bath, or by filling or flushing the component or vessel to be treated. Particularly in the case of permanently installed vessels, or those that are harder to transport elsewhere due to their size, this kind of surface treatment can only be provided via a solution delivered on site.

One alternative electropolishing technique to the standard approach of polishing in an electrolyte bath is known as anode polishing using a tampon-based process. This process – in which surfaces ranging from a few square centimeters to larger areas are treated both efficiently and economically and to the highest quality standards – is an exclusive service offered by Edelstahl Maurer AG.

Once the area has been properly ground, we use tampons in different sizes and shapes to meet the high requirements associated with individual polishing tasks.

Local electropolishing using a tampon-based process offers many impressive advantages:

• Minimal production downtime
• Treatment of the affected area only, not the whole surface of the vessel
• Excellent cost/benefit ratio
• Prompt and fast execution of work
• No need to remove the vessel to be treated
• No stress-related problems compared with filling/flushing a vessel

All work steps are logged in detail and the customer is given FDA-compliant documentation in paper and electronic form. The surface areas we re-treat using a tampon-based process look no different than the areas previously polished in an electrolyte bath.
