Have you ever noticed red rust quietly forming on stainless steel systems in pharmaceutical production? This is not just a matter of “appearance” — it’s a hidden risk that can compromise both product quality and safety.

Red rust forms when the protective passive layer on stainless steel is damaged. What develops instead is a corrosive oxide layer that clings stubbornly to the surface. It contains insoluble iron oxides and may also trap metallic elements such as nickel, chromium, and molybdenum.

**Canaan Technology: Proven Expertise in Rust Removal for Pharmaceutical Systems**

With extensive experience, Canaan has successfully completed rust-removal services for nearly a hundred pharmaceutical projects. Our reputation is built on results, not one-size-fits-all solutions. Each project is supported by engineers who assess actual operating conditions on-site and design tailored cleaning strategies:

- Optimized resource allocation — avoiding unnecessary or ineffective cleaning.
- Practical scheduling — ensuring work is completed on time without delaying production.





From routine fluid systems to critical pharmaceutical equipments, Canaan delivers precise and effective rust removal.

Whether it’s water distribution systems, preparation tanks, vacuum sterilizers, or lyophilizers, Canaan engineers develop custom solutions that restore corroded equipment and return it to reliable performance.







## **Hubei Project · Vacuum Sterilizer**

Sterilizer, as a key disinfection equipment, red rust on the inner wall appears can affect sterilization performance. Canaan team customized a cleaning process for the equipment structure. After rust removal, the inner wall was restored to a smooth, like-new condition, completely eliminating the risk of red rust particle contamination and meeting high-cleanliness production requirements.

## **Jiangsu Project · Washing Station**

If the Washing Station itself shows red rust, it can become a “source of contamination.” By optimizing the cleaning process, we completed rust removal without delaying production. The equipment regained its high cleaning efficiency, and the customer commented that the result was “better than expected.”

## **Chengdu Project · Lyophilizer**

As the Lyophilizer affects drug stability, even minor rust can impact material quality. Canaan applied a tailored cleaning process to precisely remove red rust with no residue. Subsequent validation fully met GMP requirements, giving the customer confidence in production.

## **Hainan Project · Coater**

Red rust on the inner wall of the Coater may cause uneven coating or spotting on the tablets. We designed a tailored cleaning process, after which the equipment surface was significantly cleaner, helping the customer address fluctuations in coating quality.

## **Shanghai Project · Preparation Tank**

As the preparation tank comes into direct contact with pharmaceutical liquids, metal particles from red rust pose a high risk. Canaan engineers conducted an on-site assessment and carefully scheduled the cleaning work. Rust removal was completed on time, restoring a mirror-like finish inside the tank and safeguarding the liquid from the source.
