Description
Tuff-N-Nuff® is a rockshield comprised of small diameter (approximately 0.050”) strands of flexible PVC which form a porous, non-woven mat. These strands are bonded to each other in a controlled random pattern during production.
Tuff-N-Nuff® protects pipeline coatings from direct impact during backfill operations. It also provides long-term protection by keeping hard objects in the backfill from coming into contact with the pipeline coating.
Tuff-N-Nuff® also protects the pipeline coating from these abrasive objects as lateral and longitudinal movements occur once the pipeline is placed into service.
Tuff-N-Nuff® with Rapid-Edge self fastening hook and loop system available for faster, easier installation.
In addition, Tuff-N-Nuff® does not shield cathodic protection being supplied to pipelines when installed using Rapid-Edge, monofilament tape or nonmetallic strapping as described in the Application Instructions.
Features- Laboratory and field tested to protect FBE coated steel from rocky or harsh backfill material.
- Outstanding impact resistance results in the modified ASTM G-13 rock drop testing.
- Porous and random strand matrix design does not shield cathodic protection.
