The FormaShield system, a high-strength composite repair solution, reinforces pipes by containing hoop and axial loads. The FormaShield system features epoxy resin and tri-axial glass fiber reinforcement and can be applied on site, allowing the system to be customized for operations in aggressive environments. The system is ILI detectable and meets ASME PCC-2 and ISO 24817 standards.

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.
