Corrosion issues are everywhere

VpCI diagramIt doesn’t take long to peruse the news and find stories relating to corrosion.   Corrosion is one of the most common issues that consumers and industry face and estimates indicate that billions of dollars are spent each year dealing with corrosion issues.   The following are a few news items and some comments.

Corrosion Issues with Cars

This story is about a lawsuit filed against the Ford Motor Company for corrosion issues on the hood.

Ford Mustang Hood Corrosion Lawsuit Tossed Out

The hood on the Ford Mustang built after 2006 was aluminum.   The plaintiffs contentions were that Ford knew about a “galvanic” corrosion problem with its aluminum based hood and hid that information from the consumers.   The corrosion problem manifested itself by bubbles appearing on the painted hood surface.   The hood was refinished a couple of times and paid for by Fords warrantee, but after 3 years Ford declined to pay, because non-penetrating corrosion is only covered for 3 years by its stated warranty.

The judge threw out the lawsuit on the grounds that the plaintiff did not establish that he suffered financial damage, nor was the galvanic action theory validated.

Our comments: Cortec provides several products that provide corrosion protection for aluminum based products.   In order for corrosion by galvanic action to occur, two dissimilar metals must be in electrical contact.   The story never indicated if the hood had two or more metals.

Corrosion Issues with Pipelines

The next story published in the National Observer (www.nationalobserver.com) discusses the liability issues of Canadian East Oil Pipe line.

Why corrosion might take down Energy East

The story discusses various instances in the past with other pipelines.   Major leaks or even explosions have been attributed to corrosion in oil pipelines.   The story relates a series of incidents over the last 25 years and is making the point that the new oil pipeline is an environmental hazard.

Our comments:   The fact that there have been issues in the past with oil pipe lines is indisputable,   but the author is discounting any safety measures recently adapted to mitigate pipeline disasters.   Cortec’s does have products specifically designed to inhibit oil pipeline corrosions, in fact Cortec’s products have been used on the Trans Alaskan Pipeline (read case study here). Note:   we were able to find several stories relating to oil spills on the Trans Alaskan Pipeline, but none were related to corrosion.

Corrosion Problems with Concrete

Corrosion issues on concrete structures are well known, and there have been a number of stories reported on degradation caused by corrosion of the rebar that is embedded in the concrete. We came across this story about a push in Australia to change standards for chloride induced corrosion of rebar.

Australia’s Pioneering Push for Longer Lasting Concrete

We found a couple of related articles for concrete reinforcement corrosion.

Here is a story that discusses the invention of a new sensor system that can detect corrosion problems in concrete as soon as they occur.

Another news release relating to concrete corrosion is about a new Cortec product:

Cortec’s MCI coating for rebar – superior corrosion resistance for re-inforcing metal!

Our Comments: Cortec has developed a number of effective corrosion inhibitors for concrete reinforcement over the years. Packnet does not deal with concrete structures, so we don’t provide a lot of information on our website about concrete corrosion products.

Cortec is one of the world’s leaders in corrosion protection, with 100’s of products for thousands of applications. Many businesses that encounter corrosion issues will go to Cortec for help. Cortec spends a huge amount of resources in the research and development of corrosion inhibiting systems. Packnet distributes Cortec products and jointly works with its customers and Cortec to address corrosion issues.   More info on corrosion inhibitors.
