Composite Pipe Repair

Industry: Oil & Gas

Solution: Hydrogen Pipeline Repair

ID: CPR-6-00173

Project summary:

A major gas company found defects on the weld seams of a stainless-steel pipe that transported pure hydrogen gas. The defects were likely stress corrosion related so the company decided to look into a high-modulus, carbon fiber reinforcement solution. The high-modulus system quickly reinforces the pipe when subjected to cyclic pressure and eliminates any further external corrosion, even in heat affected and stressed areas of the pipeline. A six-layer carbon fiber reinforcement system was applied to a two-meter length to enclose both problematic areas and provide a long-term life extension.
