Project summary:

A coke oven gas (COG) bypass line had a through-wall failure at an elbow. The pipe was left in service for several years, accumulating a large salt deposit and further degrading the pipe wall. The stainless-steel pipe had to be repaired to prevent dangerous gases from escaping. The leak was sealed with wooden wedges, then buried in an epoxy putty. A high-strength, high-temperature carbon fiber reinforcement system was applied to the exterior of the pipe section. This created a structurally independent composite pipe around the badly degraded host pipe.
