Retrowrap STD (Standard)
Retrowrap is used for inshore splash zone and underwater corrosion protection for piles, pipelines and risers. Designed to suit any diameter from 50 mm to 3 meters, it may be interlocked to accommodate any required protected length. Full-length Geon™ closure flanges are factory-fitted with corrosion-resistant self-threading fasteners designed to retain Retrowrap in position throughout its service life. During installation, the flanges permit the creation of induced hoop tension within the multilayer fabric, which induces the corrosion-inhibited gel to flow and totally encapsulate and protect the substrate without the use of primers, fillers or tapes.
Features of Retrowrap STD
- Easy one-piece installation; no primer, filler or tapes
- Minimal surface preparation
- Full-length flange closure for easy installation
- Easy removal and replacement for substrate inspection
- Provides active protection with environmentally safe corrosion inhibitors
- Abrasion-resistant
- Totally UV-resistant
- May be fitted with corrosion rate monitoring
Retrowrap HD (Heavy Duty)
Retrowrap HD is the heavy-duty, multi-scrim version of the STD. It is specifically designed to provide protection to offshore oil and gas risers or inshore applications subject to external impact damage. As with the STD, installation has been reduced to its simplest possible form, saving hours of diver and rigging time.
Features of Retrowrap HD
- Multilayer, heavy-duty construction
- Supplied in interlocking modular lengths
- Does not require substrate shotblast preparation
- Polyurethane provides the highest abrasion resistance
- Full-length closure flanges for easy installation
- Now available with unique anti-fouling outer layer
- Easy removal and replacement for inspection
- Provides active protection with environmentally safe corrosion inhibitors
- Hoop tension forces created within the outer skin resist high wave suction forces
- Cold-applied – no hot work permit required
