Unpiggable MFL Robotic Inline Inspection

Advanced Pipe Explorer Robotics Technology Makes Every Pipeline Accessible


Self-propelled, remotely-controlled, and fully-articulated, Pipe Explorer goes where most cannot. With a minimal footprint, the ability to operate in active pipelines, and by collecting multipoint data in one pass, Pipe Explorer is the standard against which all others should be compared.

Our fleet of Pipe Explorer advanced robots are at the heart of the value we bring our customers. Fully-articulated and tetherless, Pipe Explorer provides comprehensive data that is comparable if not superior to more conventional pipeline inspection methods, enabling visual and non-destructive inspection with multipoint data collection of natural gas transmission and distribution pipelines as well as liquid terminals, facilities, and stations regardless of the difficulty of the location or complexity of the pipeline.

How MFL Robotic Inspections Work

Throughout the inline inspection process, live video images of the pipeline and integrity data are streamed to both Intero and pipeline operators. These functions are performed without the need of a tether and without any interruption to local natural gas services. For liquid pipeline inspection, the pipes must be cleaned and emptied prior to inspection.

Step 1

hot tap fitting

Pipeline operator welds a hot tap fitting to the pipeline.

Step 2

launch tube secured to sandwich valve

Pipe Explorer launch tube is secured to an industry-standard sandwich valve.

Step 3

Explorer ILI launched

Intero operator launches Pipe Explorer into the pipeline, conducts the inspection, and retrieves the robot through the same hot tap (or a second hot tap if one is installed).

The benefits of choosing Pipe Explorer for Gas Pipeline Inspection
