Why hydrotest when you can use EXPLORER iLi?

With EXPLORER iLi you don’t have to compromise your data.

For many operators, challenging pipelines means deploying a simplified assessment methodology and accepting minimal data in return.

For those choosing hydrotesting, only an isolated portion of your pipeline is assessed and all you get is a pass or fail. If you are on a multi-year assessment cycle, this means there’s a lot you don’t know for a long time about your pipeline’s integrity.

The benefits of EXPLORER iLi compared to hydrotest.

The EXPLORER iLi is among one of the world’s most advanced inline inspection robots. Fully articulated, self-propelled, bi-directional, and tetherless, our fleet enables visual and non-destructive inspection of live pipelines, providing multipoint data regardless of the difficulty of the location or complexity of the pipeline.

With EXPLORER iLi, you no longer need to choose inferior methodologies to get the data you need:

  • Single entry and exit point; if you have existing fittings on your pipes from the previous assessment cycle, an EXPLORER iLi can be deployed without the added capital expenditure or the need to install new fittings
  • Comprehensive data collection – much more information and knowledge on the conditions of your pipe relative to hydrotest
  • Multipoint data collection including laser deformation, MFL, and video capture
  • Environmentally-friendly; no contaminated or hazardous waste water to dispose
  • Pipeline can remain in operation with no service disruption
  • Superior, comprehensive results make iLi EXPLORER a more efficient and economical choice than hydrotest

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

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.
