Atlas™
Le système FormaShieldTM est une solution composite haute résistance, qui renforce la structure de la canalisation en contenant les charges circonférentielle et axiale. La résine époxy est renforcée par de la fibre de verre avec un tissage tri-axial qui peut être appliquée sur site, ce qui permet au système d'être adapté à des applications dans des environnements hostiles. Le système est détectable par inspection interne et répond aux normes ASME PCC-2 et ISO 24817.

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. 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.
