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
