Polyguard has introduced a heavy duty extension of its Impact Resistant Outerwrap (IRO) product, Polyguard IRO HD. This new addition to the Polyguard Pipeline portfolio is designed to provide additional protection for field joint coatings and mainline coatings.
Both the IRO and IRO HD are fibre-reinforced composite mechanical protection systems that provide superior mechanical protection, eliminating coating damage to field joints on directionally drilled pipelines, boring, or areas where severe backfill conditions are present. Being moisture cured, no UV light or heating is required.
Polyguard IRO has also been proven to work in conjunction with a cathodic protection (CP) system so it can be utilised in accordance with US DOT and PHMSA codes. However, the key benefit that sets these products apart is their ability to be applied over coatings such as RD-6, Fusion Bond Epoxy (FBE), liquid epoxies, or any other coatings.
The simple application of this system with controlled set times allows for speedy coating protection and backfill while also giving the most effective results of any IRO or ARO in the market. Using this IRO allows pipeline operators to apply girth weld coatings at their ideal thickness to achieve the best performance with their corrosion barrier, rather than increasing those thicknesses and losing properties such as flexibility or impact resistance. By using a composite material which incorporates fibres you can improve flexibility, gouge, and abrasion resistance all while maintaining the effectiveness of the resin. This system should be utilised as a protective layer for all field joints that are installed by a trenchless method and will or could potentially impact a high consequence area (HCA) such as a road, building, populated area, or a body of water.
Polyguard IRO and IRO HD are registered under patent number 8522827.
