SAIG stands for Shear, Abrasion, Impact, and Gouge. These are the four major forces that damage coatings during HDD installations. Bore-Wrap® is specifically engineered to protect against all four, ensuring your pipeline coating survives pullback.

Yes, the poly-wrap is not a structural component of the Bore-Wrap system.  It’s sole purpose is to compress the resin during the cure process.  If it is not removed, it will begin to tear off inside the whole and possibly create hole obstructions or points that can shield CP. When removing, small bits may get stuck in the resin, they will not impact the performance and can be left on the surface.

The primary task before applying Bore-Wrap is to ensure the surface is clean and free from oil and debris.  Use a holiday detector to verify that the anti-corrosion coating is fully intact before applying Bore-Wrap.  Bore-Wrap bonds through a combination of surface tension, hoop strength, and compressive strength.  These factors/properties are inherent in the products design and will be present regardless of the level of surface roughening done to the underlying anti-corrosion coating.  While adding some surface roughening may increase adhesion, it is not always necessary.  For specific applications contact Denso for further information.

Bore-Wrap resin hardens as it cures.  It is a single component resin that activates with water so no mixing is involved.  The fiberglass architecture does not “cure” as fiberglass is already in it’s final state.  To check the cure, use a Calibrated Shore-D gauge on the highest point of resin to make sure the resin is cured.  Sufficient cure is at a Shore-D of 65 or greater.

Bore-Wrap is a simple application and can be completed with as few as 3 people or as many as 10.  The time to apply is usually measured in feet per minute.  With 3 people doing a girthweld protection, it is about 1.5 feet per minute.  With 6 to 10 people performing a mainline application it is about 3 feet per minute regardless of the diameter.  One key element is the volume of water that is available,  you can only progress at the speed that allows for the Bore-Wrap to be saturated.

Yes. Bore-Wrap® is water-activated, VOC-free, and cures without releasing hazardous chemicals, making it safe for use near wetlands, rivers, and HCAs.
