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.

Pipetel is excited to introduce its proprietary Inline Charging technology that infinitely extends the range of our Explorer robotic inline inspection services.

This Inline Charging technology allows Pipetel’s Explorer robots to inspect unpiggable pipelines until the batteries need charging. The operator positions Explorer under a 2 inch fitting where Pipetel’s inline charging technology is deployed to recharge the robot. Once the robot is fully charged, it continues to inspect the pipeline until its batteries need recharging again – with no interruption to the gas service. This inline charging process is repeated until the entire pipeline is inspected.

Watch for our upcoming Newsletters for more information on additional Pipetel services or see us at the two exhibitions listed below.

Central Hudson Gas & Electric Corp has become one of the first utilities in the nation to deploy the Explorer, a pipeline inspection robot, as a versatile, cost-effect, highly accurate tool that can examine lines otherwise unreachable by conventional inspection devices. Designed to function like a model train using drive and monitoring modules, Explorer is inserted into live lines with the aid of a launch chamber to inspect for anomalies in pipe walls so that utilities can proactively gain information on pipeline conditions and address potential problems early on. Outfitted with fish-eye lens cameras, lights and an array of sensors, Explorer can identify, size, and pinpoint dents, metal loss and other anomalies.

Central Hudson, a natural gas and electric utility based in Poughkeepsie, N.Y, worked closely with NYSEARCH, the research and development sub-organization of the Northeast Gas Association, together with other natural gas utilities to design, develop and test a self propelled, wireless robot to inspect natural gas pipelines from the inside.

Pipetel Technologies has inspected 2.5 miles of pipeline operated by Southern California Gas Company (SoCalGas) using a self-propelled robot in place of conventional internal inspection tools sometimes referred to as “smart pigs.” The stretch of pipeline had been deemed “unpiggable,” due to lack of flow needed to push the inspection tool through the pipeline.

As part of SoCalGas’ pipeline integrity management program, Pipetel was contracted to inspect a previously unpiggable pipeline and to provide the inspection results using their customized Datatel analysis software.

Pipetel inspected an eight-inch diameter pipeline with Pipetel’s Explorer 6/8 robotic inspection technology without shutting down the pipeline or disrupting service to customers. The Explorer 6/8 is a self-propelled and bi-directional robot. Conventional tools were not an option since the pipeline did not have sufficient flow to propel these tools. A cased segment of this pipeline, underneath a railway track, was also inspected.
