Getting High-quality Data Regardless of the Pipe-type

The robotic pipeline inspection method has become more widely used in the last decade, especially in the assessment and evaluation of natural gas and liquid product pipelines. Significant advances in robotics coupled with the relative ease of implementation of inline inspection, have led this development.

But how good is the data compared to alternative methods?

In the last Pipetel newsletter, we shared an article written by PSE&G, on their use of our Explorer robot to inspect some of their pipelines that were in difficult locations (see previous story in this News section). More and more pipeline operators are choosing Pipetel to inspect their pipelines due to the Explorer robot’s ability to inspect pipelines in difficult landscapes and their ability to acquire accurate and reliable data.

For years, utilities like PSE&G have used equipment called “pigs” to inspect the inside of gas pipes for corrosion, damage by excavators and other signs of trouble that could cause leaks and, in extreme cases, explosions like the one that rocked San Bruno, California, in 2010.

Talk to the robotic pipeline inspection experts to discuss how Pipetel can provide valuable data and improve the safety of operating your pipeline assets.

Pipetel will have a booth at CGA, and will have representatives at the NACE Corrosion Conference, and AGA Operations Conference. Pipetel will also participate as panelist at the Western Energy Institute Conference.

On March 30 at 10 am, Paul Laursen will be a panelist during the “Inline Inspection Technologies for Unique Applications” session at the Western Energy Institute.

The Explorer 16/18 has recently inspected a long, difficult pipeline under a roadway for a pipeline operator. The Explorer 16/18 was chosen for this project due to its versatility making it the ideal inline inspection tool for natural gas pipelines with: limited or no flow, short radius or mitered bends, valves, back-to-back bends, and pipelines that cannot be inspected by conventional inline inspection tools or other assessment methods.

Pipetel’s fleet of Explorer robots have been inspecting unpiggable pipelines since 2010 and they have proven to detect, locate and measure common pipeline threats including:

  • corrosion
  • manufacturing flaws
  • dents, and
  • mechanical damages

These Explorer robot inspections have also been successful in identifying construction features and providing additional pipeline information that are valuable to operators. This information helps operators verify and complete their records to better understand the configuration and construction of their pipelines.

Pipetel has been inspecting 8 inch gas transmission pipelines since 2010 that were previously unpiggable due to operational and configuration limitations.

Now our Explorer 8 is equipped with:

  • high resolution MFL sensors for measuring metal loss
  • Laser Deformation sensors for measuring deformations including dents and ovality
  • high resolution cameras for visual inspection

Similar to other Explorer robots in our fleet. Explorer 8 inpsects unpiggable pipelines with no interruption to the gas service as it is tetherless and self-propelled.

Pipetel inspects 6 to 36 inch natural gas pipelines that are unpiggable by free-swimming, inline inspection tools and that are tightly integrated with other urban infrastructure.

  • no interruption of gas services during inspection
  • Pipetel inspects 6 to 36 inch diameter unpiggable pipelines
  • high resolution Magnetic Flux Leakage (MFL) Sensors measure metal loss
  • Laser Deformation Sensors measure deformations including dent and ovality
  • high resolution cameras for detailed visual inspection
  • detailed actionable customized reporting

Going to the UPSF or AGA Operations Conference in May?

Pipetel is exhibiting and co-presenting at both events.

Pipetel is introducing the Explorer 16/18 robot to inspect 16 and 18 inch diameter pipelines in 2015, to expand its range of Explorer robots. The Explorer 16/18 is the last remaining size in the Explorer fleet for inspecting unpiggable pipelines from 6 to 36 inches in diameter.

“This is our latest robot and incorporates years of experience from inspecting unpiggable pipelines, to offer the most advanced and reliable fleet of robots,” says Paul Laursen, President of Pipetel Technologies.

June 2014

Pipetel Technologies has released a comprehensive video of an unpiggable natural gas pipeline inspection. This video is an excellent documentation of an inspection as well as a first hand visual chronicle of a Pipetel inspection from start to finish.


The inspection was of a pipeline segment that was previously unpiggable. The pipeline operator needed to assess the integrity of the pipelines and had not been able to obtain this information in the past. The video also demonstrates some of the features that are available on the Explorer robots such as Inline Charging technology that eliminates the step of removing the robot from the pipe to recharge its batteries and the Laser Deformation Sensor that measures the dimensions of dents.

February 2014

Pipetel Technologies has introduced a new, innovative technology to its range of Explorer robots that will measure the size of dents in unpiggable natural gas pipelines.

Available initially on the 20 inch to 36 inch Explorer robots, this laser based sensor will now allow Pipetel to not only pinpoint the location of the dent but also its exact measurements. This is important as the information, along with our metal loss inspection data, will allow the pipeline operator to decide if the dent requires immediate attention.

Pipetel Technologies has recently inspected a section of Southwest Gas Corporation’s (Southwest’s) 6 inch natural gas pipeline in Las Vegas, Nevada.

Southwest serves aproximately 1.9 million customers in Arizona , Nevada and California. Southwest has been successful due to its philosophy of excellence in the communities it serves, which is why they are committed to a strict pipeline integrity program, that delivers gas safely to their customers.

As 2013 winds down, Pipetel is closing in on its fourth anniversary. When we first opened our doors we knew we had a technology that would revolutionize unpiggable pipeline inspection services. With the support of many industry institutions and a select customer base, our goal was to quickly become the leader in unpiggable gas pipeline inspections.

In the past year we have:

  • grown our customer base by almost 100% over the previous year
  • increased our explorer robot inspections in unpiggable pipelines by 50%
  • introduced our 3rd robot, the explorer 20/26 to inspect 20 to 26 inch pipelines
  • started using our proprietary inline charging technology to extend the length of pipeline inspected

With unprecedented growth, this leadership position has been well earned by helping to improve safety and protecting pipeline assets through continually introducing innovative technology and exceeding our customers service expectations.

Pipetel has been inspecting unpiggable pipelines for nearly 4 years and recently had the opportunity to carry out a milestone inspection, which was completed last week.

Our Explorer 10/14 inspected 2.7 miles of 10 and 12 inch dual diameter gas pipeline under live conditions and without reduced gas flow. At one point the Explorer 10/14 was in the pipeline for 36 hours so it was important to keep delivering gas to customers downstream.
