Polyguard Products Non-Shielding Coatings, Anti-Corrosion Gels and Vapor Barriers
Polyguard Products has been manufacturing underground pipeline coating systems for buried pipelines since 1953. The specialty product, the RD-6 coating system, proven in the North American market since 1988, is the only proven field-applied coating that is non-shielding to cathodic protection currents in case of a disbondment from the substrate.
The RD-6 has been declared Mobil Asset Services’ number one rehabilitation and maintenance system in a public study versus all other contemporary existing field technologies present in the market.
Polyguard Products prides itself on innovative technologies that differentiate it from mass market products.
Non-shielding coating system for underground pipelines
The RD-6 buried coating protection system was launched in the American market in 1988 and has since been used on many thousands of applications in all industrial continents. Thus, the performance has been proven for more than 3 decades of buried life and Polyguard’s presence with this product continues to expand.
The non-shielding properties mean that, if the RD-6 disbonds from the metal and water enters between the disbonded coating and the metal and adequate cathodic protection is being used, there will not be corrosion on the metal. This property has not only been proven in labs in North America, Europe and Asia but also by repeated field experiences.
This is important as shielding technologies (which are specifically mentioned by coating type by the Pipeline Hazardous Materials Safety Administration) are regulatorily prohibited in the USA since 2010 by PHMSA. NACE SP-0169 also cautions against shielding since 2007, and other national standards bodies in Latin America and Asia prohibit shielding. And since 2015 ISO cathodic protection standard 15589 also cautions against shielding.
Soil stress-resistant coatings for oil and gas pipes
The product offers superior soil stress resistance compared to traditional tape systems, thanks to the polypropylene mesh backing and superior substrate adhesion.
The ability to resist soil stress is vital to a pipeline coating’s performance, thus the RD-6 offers a much better resistance to soil stress as well as the capacity to allow cathodic current flow in case of a disbond.
Insulation vapor barriers for refinery and LNG plants
Polyguard also manufactures a range of insulation vapor barriers, including an innovative alternative to metal jacketing called Alumaguard. The vapor barriers have been installed on numerous refinery and LNG plants worldwide, and Alumaguard has replaced a large percentage of the traditional metal jacketing in North America for over ten years.
Alumaguard is competitively priced compared with metals, installs in a fraction of the time, does not require skilled labor and is fully waterproof, in addition to being a self-healing vapor barrier that doesn’t require fasteners.
