Bare pipe Internal corrosion

Taking Corrosion Detection Even Further

In our previous article on CUI, we shared a bracelet technology that you can place on your pipe that scans for outside corrosion underneath up to just over 2 inches of insulation.

Today, I want to share two more bracelets – one that lets you detect internal corrosion on bare or near-bare pipe, and another that lets you scan concrete pressure pipe for compromised structural integrity.

Bracelet 2 – Detecting Internal Corrosion

A second version of the bracelet uses its electromagnetic frequency to penetrate the pipe wall, providing you insight on the internal condition of your pipe. The bracelet is fitted with sensors that measure the alterations in the field caused by the internal corrosion.

Below is a sample scan of a pipe section, with the color indicating the pipe condition. The yellow and red areas indicate corrosion.

This uses the same process and software as the first bracelet, providing you data on your pipe in near real time.

Individual pits, graphitization and erosion are all immediately visible.

Trends in wall thickness reductions are easily seen and understood.

You can get an accurate reading on your internal corrosion in much less time than traditional methods, and will know exactly the condition of your piping.

Depending on the thickness of your pipe, you can scan up to 12 feet per minute on horizontal or vertical piping while only needing a few scans to cover the whole pipe with the 10 inch wide scanning ability.

Bracelet 3 – Concrete Pressure Pipe

A less common version of pipe known as concrete pressure pipe is used most often to carry water or wastewater, and these pipes have an intricate construction that makes detection of internal defects very valuable.

Concrete Pipe

The way these concrete pipes are made is by applying grout or concrete on the inside and outside of a very thin steel cylinder, then wrapping a high tension wire around the outside, and covering that with more grout or concrete.

The wall thickness might be around 7 inches thick.

This modified version of the bracelet can scan one of these pipes and find one individual broken piece of wire within the concrete.

The high tension wire is what gives the pipe structural stability, so being able to detect one piece of broken wire on these pipes is a useful application that gives facilities the ability to scan their concrete pipe and know if the structure is compromised.

Cost Efficiency

The three bracelets I have shared with you will help you drive cost efficiency by speeding up your scans while requiring very little crew to do so.

With this technology, you can detect corrosion under insulation on insulated pipe, internal corrosion on bare or near bare pipe, and internal structural integrity on concrete pressure pipe…

All with as little as a 2 man crew.

The instant data reporting gives you the ability to act instantly and take any necessary actions without waiting for data analysis.
