Diakont has developed a fleet of in-line inspection robots, called RODIS crawlers, to support the asset integrity of gas and liquid pipelines by detecting and measuring internal and external metal loss, corrosion, and various other anomalies. Not only is this collected data highly precise, but it can be observed in real time while the inspection is taking place, providing immediate access to crucial information that utilities and pipeline operators require to facilitate integrity management programs and meet federal pipeline safety standards (49 CFR Part 192 and 195). From a single access point, our crawlers can be launched and retrieved to inspect up to 1,800 feet of pipe. Diakont’s fleet of robotic ILI tools can accommodate pipelines ranging from 8” to 55” in diameter.

Common RODIS Crawler Inspection Applications

Insulated or lined pipes
Road or river crossings
Offshore pipelines
Upstream gathering systems
Buried or cased refinery piping
Municipal steam or water pipe
Compressor and pump stations
Survey of lines with missing or suspect documentation
High-Accuracy Data on Tough-to-Access Lines

Diakont’s RODIS crawlers minimize or eliminate excavation requirements by travelling to crossings or other target pipe sections from convenient access points close to grade level. In addition to the line types described above, our tools perform pipe inspection on sections previously considered “unpiggable,” including:

Verticals, <1.5D bends, mitre bends, back-to-back elbows
Low-flow
Significant diameter or wall thickness changes
Unbarred tees
Inspection under casings or insulation
No launchers / receivers
High-consequence areas (HCAs)
