Composite Repair for Service Water Line Reducer Leak

RAK repaired a leak on a 32″ to 20″ reducer on a service water line by stabilizing the area, preparing the surface, and applying an epoxy and carbon fiber composite wrap system. The repair restored the reducer’s integrity and ensured safe, reliable operation while minimizing downtime.

The Problem

A 32″ to 20″ reducer on a service water line was identified to have a small leak at the 9 o’clock position. The operating pressure of the system was 30 psi. The leak posed a risk of further deterioration and potential failure of the reducer, which could impact the efficiency and safety of the service water system. Immediate action was required to address the leak and reinforce the integrity of the reducer.

The Solution

The repair was conducted by the RAK crew and involved multiple steps including addressing the leak, sandblasting, applying an epoxy tack coat, and installing a composite wrap. The use of epoxy and carbon fiber materials, combined with thorough surface preparation and coordinated team efforts, resulted in a durable and reliable solution to the problem. The repair was completed successfully, restoring the integrity of the reducer and ensuring the continued safe operation of the service water line.
