corrosion and materials

As ships and platform structures age, they deteriorate through corrosion and fatigue. External deck corrosion has become a major concern for owners and operators. Marine vessel deck plates and upper shore structures are constantly exposed to a highly corrosive environment (saline medium), not to mention various forms of mechanical actions.

The External Corrosion Direct Assessment (ECDA) methodology, proposed in the NACE SP0502 Pipeline External Corrosion Direct Assessment Methodology standard, represents an option for pipeline sections that cannot be inspected with smart pigs for reasons such as: low flows, no provision of launch traps, obstructions in the line, changes in diameter, among others

The use of soluble inhibitors in the corrosive medium are the commonly used alternatives due to their low costs, easy application and maintenance. Due to the toxicity of the substances traditionally used as inhibitors of the corrosive process, there is a growing interest in the development of a series of investigations aimed at exploring efficient, economical and environmentally friendly inhibitors.

Corrosion is a natural process of material degradation, with multiple consequences, not only economic, but also environmental and human.
Current research has focused its studies on the problems presented by metallic corrosion, caused by the progressive deterioration of the environment. However, there are few studies on the reverse case in relation to the effect that corrosion has on the environment.

This time we head to North East England (UK) specifically to Gateshead, County of Tyne and Wear whose capital is Newcastle, to talk about a relatively new iconic structure known as The Angel of the North. What makes this monument special, apart from its impressive dimensions and construction process, from the point of view of a corrosionist, is the material used.

Article on bacteriological corrosion. Some bacteria thrive in anaerobic conditions and produce compounds that cause iron oxidation ..

Corrosion works 24 hours a day, 365 days a year, and does not require a quote to do its job, do you?
Have you established how much you have to invest annually to replace parts and structures due to corrosion damage?

Summary In this article, it is intended to describe the corrosion processes associated with exposed metal structure systems in environments with high relative humidity; causing

This article presents a summary of the importance of the application of paints on welds (Field Weld), complying with the specifications of the standards, procedures and additionally represents information of interest to professionals and technicians associated with the industry.
