In the pursuit of bringing hydrocarbons to market, there are many obstacles, both natural and man-made. Some of these difficulties can be circumvented, but others, like corrosion, are unavoidable. As much as oil and gas production companies would love to dodge this process altogether, it’s a natural part of chemistry and physics, and it’s not going anywhere any time soon. Over the decades, many technologies have been created to resist or prevent corrosion-damage to pipelines. These pipelines are essential to the delivery of hydrocarbons, but are susceptible to corrosion damage from the heat, moisture, and abrasives that are often present in these working conditions. One such technology used in the battle against corrosion is fusion bonded epoxy coatings (FBE).
FBE coatings are supplied by multiple manufacturers. Axalta is a leading provider of protective coatings throughout North America, offering an array of high-tech FBE options. Axalta Nap-Gard® 7-2500 Fusion Bonded Epoxy is one such coating, designed to provide corrosion protection in the demanding oil and gas production environment. In addition, Nap-Gard® 7-2500 is used in transporting wastewater and saltwater, each of which present their own challenges that must be addressed.
Nap-Gard® 7-2500 is designed to provide protection for both internal and external surfaces of pipeline. The protection of both surfaces is important: internal surfaces are exposed to chemically-active hydrocarbons, while outside surfaces can be exposed to high heat, high pressures, and abrasives such as salt. The 7-2500 specification is formulated to withstand high temperatures of 107°C (225°F)—vital heat protection in the unforgiving oil and gas production environment. In addition to providing this protection for oil and gas applications, the product complies with NSF-61 specification, meaning that it’s approved for transporting potable water.
