Description of Main
Features
Main Benefits
Claimed
Application of carbon fiber composite to interior surface of pipe. Carbon Wrap
is used to strengthening buried pipes, especially PCCP with broken wires.
Concrete and steel pipes can be strengthened to take pressures even greater than
that of their original design.
• Requires no excavation.
• Increases pipe strength to even higher than its original pressure rating.
• Requires no heavy equipment for installation. Access thru 24 inches
manways.
• Cannot be used if the temperature is above 200 o F
Main Limitations
Cited
• Cost for application can be high versus post-tensioning with steel tendons.

III. Technology Design, Installation, and QA/QC Information
Product Standards NSF 61 compliant
Design Standards ACI 440 (design standard for externally bonded FRP systems for concrete
structures)
Design Life Range Minimum 25 years
Installation Standards As per manufacturer guidelines.
Installation
In the case of 36 inches and larger diameter pipes, simple access is made through
Methodology the manholes and all operations are conducted internally. If the pipe can be
accessed from the outside, the wrapping can be performed on the outside face of
