RD-6
| Polyguard RD-6 Coating System is a non-shielding anti-corrosion system used on buried and submerged line pipe, rehabilitation and new construction girth welds. RD-6 can also be used above ground but the coating must be protected from harmful UV rays by using RD-6 UV Overcoat. It consists of a liquid adhesive, a geotextile backed protective pipeline coating and SP-6 outerwrap. RD-6 is compatible for pipelines operating up to 145°F (63°C); for pipes operating above 145°F, RD-6 HT must be used. Corrosion protection results from the polymer modified coating layer. Bonded to the outside surface of this coating is a strong, tightly woven, polypropylene geotextile fabric, which provides non-shielding properties plus high breaking strength and low elongation. RD-6 coating is manufactured in rolls for ease of application using a Polyguard approved machine such as the Wrapster or power operated machine. RD-6 is produced with a silcone coated release liner to prevent the layers from adhering to one another and assist in the application process. |
