Consisting of high-strength proprietary glass fiber reinforcement, the moisture-cured A+ Wrap™ advanced composite repair system is commonly used for pipelines and piping systems experiencing corrosion or mechanical damage.


Following the ASME PCC-2 and ISO 28417 standards, A+ Wrap™ reinforces a pipe by containing hoop and axial loads, thereby reducing strain in the defect region. The system requires no special tools for application and sets within an hour after installation.

1. Surface Preparation 

Remove all soft coatings and media blast the pipe to a 2.5 mil profile (NACE 3 minimum). Wipe the surface with a solvent such as Acetone, Toluene, or MEK.


2. Load Transfer Filler 

Mix the putty or paste until uniform in color and apply to any defects. Shape the filler to near net surface profile of pipe.


3. Adhesive Primer 

Mix equal parts of the adhesive primer until uniform. Apply the primer to the pipe surface, ensuring a minimum of 30-mil coverage. Allow the primer to sit until a “peanut butter” thickness is achieved.


4. A+ Wrap™ Preparation

Remove the A+ Wrap™ from the foil pouch and submerse in water for 1 minute. Wrap the material around the pipe, while spraying each layer with water. Apply uniform tension during application.


5. Apply Compression Wrap 

Tightly apply 4-6 layers of compression wrap over the repair. Perforate the surface of the compression wrap to enable out-gassing.


6. Apply Top Coating if Needed 

Allow two hours for the A+ Wrap to harden before removing the compression wrap. Afterwards, if needed, apply the pipe coating.
