Advanced technology for electropolishing as surface treatment
Calamo have the largest and most advanced electropolishing facility in Europe. We have 50 years of experience and are continuously developing and innovating the electropolishing process. This means we can offer electropolishing for many types of steel, in almost any size and shape. Our electropolishing of pipes and tubing is very likely the most modern and efficient in the world.
Our new sub-contract electropolishing facility can handle many sizes and shapes: anything from the size of a pin-head to constructions weighing up to five tons. Our other facilities allow us to meet the most varied and rigorous requirements and demands.
Areas of application
Electropolishing is used where there are high demands for cleanliness, resistance to corrosion and hygiene.
Examples of areas of application:
- Pharmaceutical manufacturing
- Equipment for sterilizing and disinfection
- Food manufacturing, e.g. dairy, oils
- Paper and pulp
- Nuclear power equipment
- Processing industry, e.g. treatment plants, chemical plants
- Automotive, decoration and corrosion protection
- Marine environments, corrosion protection and durability
- Buildings, e.g. facades
Advantages from electropolishing as surface treatment
A surface that has been electropolished has many advantages: it’s free from pollutants that affect corrosion resistance, cleanliness, durability and washability. Electropolishing removes 20µm (0,02 mm) from the surface. There is often residue and pollutants from the manufacturing process on the surface. These can negatively affect the desired levels for cleanliness, resistance to corrosion and microstructure.
An electropolished surface:
- Has a passive layer protecting against corrosion
- Is easier to clean due to a smoother surface
- Is less intrusive towards surrounding media
- Simplifies disinfection and sterilization due to its much smoother surface
The more common grades of steel we electropolish are austenitic, ferritic and austenitic-ferritic (Duplex), and high-alloy grades of steel such as Hastelloy.
