Life Prediction & Extreme Value Statistics

At Corrosion Clinic, our NACE certified corrosion specialist is able to provide corrosion advisory services, professional consultation, in-house training, online and distance learning corrosion courses, corrosion diagnosis, failure analysis and expert witness in litigation and arbitration cases related to corrosion, materials, metallurgy, paints & metallic coatings including thermal spray metallizing, galvanizing, anodizing, chromating, phosphating, electroplating, electroless plating, mechanical plating, and sheradizing or diffusion coating.
 

Extreme value statistics is a powerful tool in corrosion data analysis and especially in life prediction of corrodible structures and components. If your job requires you to do life prediction and remaining life estimation of equipment and structures, you have probably come across terms such as "Gumble distribution" or "Weibull distribution".  Applying the powerful extreme value statistics to corrosion data analysis, one can achieve more realistic life prediction and remaining life estimation of equipment or structures such as pipelines, storage tanks and highway bridges.

At Corrosion Clinic, we can analyze the supplied corrosion data, or conduct on-site survey, inspection and measurement of the relevant corrosion data and provide you with a technical report that contains detailed extreme value statistical analysis of your corrosion data, and the remaining life determined from the extreme value statistics.

• " I have a 20-year old fuel pipe (API schedule 40, thickness: 8.1 mm;  dia.: 200 mm) that is experiencing severe pitting corrosion recently. There have been no leaks so far but I am concerned with the probability of leaks in the near future. How can I determine the remaining life of the fuel pipe?"
