Axalta Nap-Gard achieves new depths for oil pipelines

Axalta Coating Systems is rolling out its latest generation Nap-Gard® product which can withstand continuous operating temperatures of 155°C (311°F). Nap-Gard High Tg 7-2555 is a thermosetting epoxy powder designed for use as a corrosion barrier coating for underground and sub-sea pipelines that operate in high temperature service. It can be used as a corrosion coating in a stand-alone or dual-powder coating system or as a corrosion coating under multi-layer insulation systems. When used in conjunction with Axalta’s most recent dual layer system Nap-Gard 7-2675, the operating system increases to 180°C (356°F). The second layer ensures reduced water permeability and improved chemical resistance.

“Our latest Nap-Gard product is a breakthrough in fusion bonded epoxy powder coatings,” explained Mike Cash, Senior Vice President of Axalta and president of its industrial business. “Designing a coating for higher temperature operating systems enables our customers to extract oil from greater depths and more extreme conditions, resulting in higher performance and increased productivity.”

Nap-Gard 7-2555 is currently approved by operating companies in Mexico, Colombia and Venezuela. It is presently being applied on a 50km project in Mexico. Nap-Gard 7-2555 builds on the previous generation Nap-Gard 8-2535 which was designed for operating temperatures up to 135°C (275°F).

"Axalta scientists developed Nap-Gard 7-2555 to meet the demanding needs of pipeline customers," stated Dr. Fred Allen, Axalta’s Director of Global Powder Technology. “Our understanding of material properties enabled optimization of product performance relating to corrosion inhibition, chemical resistance, and high temperature stability under harsh operating conditions. Research continues in order to improve stability even further."

Nap-Gard 7-2555 and 7-2675 are available to customers around the world.
