1. Carbon Wrap vs. Component Replacement
Stronger than steel
Doesn’t corrode
External application without shutdown (for non-leaking pipes)
No welding – No hot work permits - Safe
Require less time to install
Often lower overall cost*
Welded sleeves are 24% more expensive
Replacing damaged sections completely are 73% more expensive

2. Structural Repair Systems
Carbon fiber reinforcing material
Epoxy matrix material and primer
System can share the load with the
remaining pipe wall
System can be designed to withstand
100% of load in the presence of a thru-wall
leak
