LEEDS, England — Leeds, England-based paint and coatings manufacturer Corrocoat has passed the NORSOK Standard 501 test protocol for its Plasmet ZF coating system.

NORSOK standards were developed by the Norwegian petroleum industry to ensure the safest and most cost-effective products in engineering, manufacturing and maintenance of structures in the oil and gas industry. To achieve NORSOK 501 standard, a coating system must demonstrate high levels of protection with a minimum need for future maintenance and low environmental impact.

After six-month long exposure tests for cyclic ageing, seawater immersion and cathodic disbondment, the coating performed extremely well, passing all tests. 

Plasmet ZF was tested against System 1 - use on carbon steel with a max operating temperature of <120 °C - structural steel, equipment exteriors, vessels, pipework and valves (including in tidal and splash zones); and System 3B - internal surfaces of carbon steel vessels - ballast water tanks/internal seawater filled compartments.

The NORSOK testing was conducted by SGS, an independent inspection and testing organization. SGS commented that the results on the cathodic disbondment tests were “exceptional” reporting that they could not even get a knife blade between the coating and the steel after 175 days on test.

“Corrocoat specialist paints and coatings have been used for years in demanding energy applications throughout the world,” said Sales Director Rob Cole. “NORSOK approval is unbiased confirmation of Plasmet ZF’s performance and confirms our position as a leading provider of corrosion protection and engineering services to the offshore and marine industries. Our customers now have an added level of confidence that Plasmet ZF will meet their toughest requirements.”
