A major North African based transmission pipeline operator recently excavated a section of 42’’ high pressure gas transmission pipeline. Locating the repair in the middle of the desert was a simple and quick operation due to the marker band performance and GPS within the ILI. 

After ILI inspection, new corrosion was found on either side of the Clock Spring reinforcement, but the Clock Spring coils were still hard at work protecting the pipe and the environment.  Additional Clock Spring repairs will now be installed extending operational performance decades into the future.
