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. FormaShield Preparation 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. |
