An inspection team in Indonesia discovered external pipe defects caused by alkaline soil on a section of buried 28-inch (711-mm) pipe.

The erosion had resulted in significant mechanical damage. The asset owners wanted an immediate repair that would allow them to restore the damaged line to a safe operating condition.

Following excavation, a Clock Spring trained and certified team of installers manually prepared the pipe surface for a Clock Spring sleeve repair designed to reinforce the weakened section of pipe.

The installation team installed 4 Clock Spring repair sleeves under the supervision of a Clock Spring Supervisor, restoring the line for safe operation within a single day.
