For the customers & markets that we serve, Corrosion represents the difference between trouble-free operation and costly downtime.

What is Corrosion?

According to NACE, Corrosion is the deterioration of a substance,
usually a metal, or its properties because of a reaction with its environment.

The Problem of Corrosion

Direct and indirect economic losses derived from corrosion include the following:

  • Replacement of damaged equipment
  • Overdesign to allow for corrosion
  • Preventive maintenance
  • Shutdown due to corrosion failure
  • Loss or contamination of the product being produced (i.e. food industry)
  • Efficiency decrease. For example, corrosion products lower the heat transfer
    rate in heat exchangers
  • Failure of adjacent equipment
  • Health and safety. Loss of natural resources,
  • pollution or even human lives.

Using the right materials and processes can help to beat corrosion problems throughout the industries we serve.

Uniform Corrosion

Uniform or general corrosion is the most classical form of corrosion, but is not always the most important in terms of cost or safety. The consequences of uniform corrosion are a decrease in metal thickness per unit time or a more or less uniform deposit of these corrosion products in the surface of the metal. Uniform corrosion can be limited or prevented by an appropriate choice of material or modification of the medium among other solutions. Using the right materials and processes can help to beat corrosion problems throughout the industries we serve.

Galvanic Corrosion

Galvanic corrosion can be defined simply as being the effect resulting from the contact between two different materials in a conducting corrosive environment.
In many cases, galvanic corrosion may result in quick deterioration of the least corrosion resistant material, and can lead to fatal failure. Common methods of minimising and preventing galvanic corrosion are choosing material combinations in which the constituents are all made from the same material or different materials as close as possible in the corresponding galvanic series, avoiding an unfavourable surface area ratio, using protective coatings, or controlling the aggressiveness of the environment.
