Pipe Wrap A__Wrap.jpgFabricado con un refuerzo de fibra de vidrio, con una alta resistencia patentada, el sistema avanzado de reparación compuesta A+ WrapTM comúnmente se usa para ductos y sistemas de tuberías que sufren de corrosión o daños mecánicos. Siguiendo los estándares ASME PCC-2 e ISO 28417, el A+ Wrap refuerza una tubería al contener las cargas de fleje y axiales, lo que reduce la tensión en la región del defecto. El sistema no requiere herramientas especiales para la aplicación, y se fragua en menos de una hora después de la aplicación.

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.png2. 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.png3. 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.png4. A+ Wrap™ Preparation
Remove the A+ Wrap™ from the foil pouch and submerse in water for 1 minute. Wrap the material around the pipe, while spraying each layer with water. Apply uniform tension during application.

 

 

5.png5. Apply Compression Wrap 
Tightly apply 4-6 layers of compression wrap over the repair. Perforate the surface of the compression wrap to enable out-gassing.

 

 

 

6.png6. Apply Top Coating if Needed 
Allow two hours for the A+ Wrap to harden before removing the compression wrap. Afterwards, if needed, apply the pipe coating.
