Anomaly Description:
Through hole found in T-piece welding resulting in steam leak.

Root causes:
Internal corrosion and possible welding defect on the T-Piece weld.

Integrity concerns:
Further deterioration of weld could result in separation of the T-piece from the piping, this could have resulted in possible shutdown of equipment and production loss.

Because there is a possibility of a complete weld failure, a strongback system had to be put in place to keep the system intact in the event that failure of the weld occurs. Space below the T-piece enclosure was very limited and Beruseal devised a plan to design a restraint that would go around the larger diameter pipe and tie in together with the enclosure.

Conclusion:
A polymer compound was injected into a sealing groove to avoid sealant entering the line through the defect. A safe and successful repair was implemented that allowed the client to operate at full capacity until the next planned shutdown.
