FormaShield®

The FormaShield system, a high-strength composite repair solution, reinforces pipes by containing hoop and axial loads. Its epoxy resin features 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.

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 2.png

 

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 8.png

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 9.png

 

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.
