Corrosion Inspection & Testing Analysis- Copper, Aluminum, Nickel

Corrosion testing provides us valuable information that can be very helpful in preventing costly damage or premature failure of components and structures. Survey done by NACE International shows that about $300 billion are lost by the US Economy due to corrosion.

Corrosion can be detrimental if not diagnosed or detected timely. Failures due to corrosion can be harmful to humans, personnel property and also the environment. To avoid losses of this nature, corrosion testing should be performed in every kind of industry from refineries to utility companies.

The adage goes that best treatment is preventive. It very much applies to corrosion prevention programs.

Corrosion testing can be broadly classified into four parts:

  • Laboratory tests
  • Pilot plant or semi-works tests
  • Plant or actual service tests
  • Field tests

Why do we need corrosion testing?

Corrosion tests are performed for four main reasons which give us an accurate and precise result for the following reasons:

  • Control of corrosion resistance of the material or corrosiveness of the environment.
  • Study of the mechanics of corrosion or other research and development objectives.
  • Evaluation and selection of a metal or alloy for a specific environment or a given definite application.
  • Evaluation of new or old metals to determine the environments in which they are suitable or not suitable.
