Non Destructive Testing on

Refrigeration Piping Systems

 

GGS performs NDT testing on refrigeration piping systems. We scan your in-service piping without cutting holes or removing the jacketing and insulation to provide a complete data set with real-time information. Radiometric Profiling technology, the best option for testing refrigeration piping, offers a non destructive and non disruptive evaluation of your system.

1

No holes in piping insulation.

There is no need for insulation removal or pipe cleaning, we test your pipes as they are.
2

100% Safe.

There is no radiation exposure risk, facility staff can be present during testing.
3

200 Test locations per day.

Rapid scanning allows for optimized productivity and a more thorough evaluation.
4

No accessibility limitations.

All piping in your facility – including congested and suspended – can be accessed and tested.
5

360° Complete coverage.

We read everything in the beam, wall to wall, top to bottom for a complete profile of the pipe.
6

100% Real-time results.

Instant measurements allow for on-the-spot analysis and further investigation of anomalies.

Our Approach

for Refrigeration Piping Systems

GGS understand the characteristics of refrigeration piping systems, how and where damage can occur, and how it progresses over time. This results in an approach that is specific to your environment and testing that is conscious of the functions of your system. Whether you are performing a routine assessment, evaluating for maintenance or need to learn more about suspect areas, our experience ensures pragmatic results.

Corrosion Under Insulation (CUI) is the most prevalent form of pipe degradation. CUI in the refrigeration industry usually occurs on the top and bottom of horizontal piping. Refrigeration piping usually operates at temperatures below ambient. As a result, water vapor will condense on the external surface of carbon steel piping wherever there is a breach in the vapor barrier of the insulation.

Once water is in contact with the carbon steel, external corrosion will continue to progress until it is resolved. Any water that has entered the insulation will either freeze on the pipe (if it is operating at or below 32F), or it will remain a liquid. This liquid may travel considerable distances from where it was first introduced into the insulation. Water will seek the lowest and/or coldest point in the piping system and remain a constant threat to the integrity of refrigeration piping.

Most refrigerants, including anhydrous ammonia, are not detrimental to the internal surface of carbon steel piping and vessels. For this reason, the presence of external corrosion, not (internal) erosion, is a characteristic of degradation in ammonia refrigeration piping systems.

Testing reveals detailed conditions found at each location. Conclusive wet insulation volumes, severity of corrosion and wall thickness values allow for informed maintenance or replacement planning.

Reported Conditions

for Refrigeration Piping Systems

GGS non destructive testing results in reliable diagnostic data on your refrigeration piping system. We detect and measure the following system components and damage mechanisms present in refrigeration process piping and vessels:

  • Pipe Schedule
  • Pipe Wall Thickness
  • Corrosion
  • Welds
  • Wet Insulation
  • Blockage

Your testing report, which can be used to support multiple facility management initiatives, includes visual, quantitative and qualitative data of each individual scanned location.
