Description
Following the ASME PCC-2 and ISO 28417 standards, the moisture-cured Atlas™ composite repair system reinforces defective pipelines and piping systems by containing hoop and axial loads. Consisting of high-strength proprietary carbon fiber reinforcement, it is easy to install and sets within minutes.

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. Preparing the Wrap Mix epoxy parts A and B for at least 2 minutes. Apply the mixed resin onto the fabric evenly distribute on the fabric. Roll up the fabric and transfer to the prepared pipe. |
|
5. Apply Wrap to Pipe Apply cloth tightly around pipe and continue wrapping until designed layer count is achieved. |
|
6. Constrictor Wrap Tightly apply 4-6 layers of constrictor wrap over the repair. Then, perforate the surface of the wrap. Allow 2 hours for curing. |
|
7. Topcoat Application After the epoxy has cured, remove the constrictor wrap. Apply a topcoat to the repair area, as applicable. |
