Corrocoat submitted Plasmet ZF for independent testing to NORSOK Standard M-501 by world leading inspection and testing organisation SGS. NORSOK standards were developed by the Norwegian petroleum industry and describe in detail how to achieve the safest and most cost-effective products in design, engineering, manufacturing and maintenance of structures in the oil & gas industry.
To pass the NORSOK Standard m-501 test protocol, a coating system must demonstrate high levels of protection with a minimum need for future maintenance and health, safety and environmental impact.
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.
After six-month long exposure tests for cyclic ageing, seawater immersion and cathodic disbondment, the results were received and the coating performed extremely well, passing all tests with flying colours.
As testament to the success of Plasmet ZF, 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 steel after 175 days on test!
So, great results for an outstanding coating that has now passed all of the relevant NORSOK tests and is now the ideal choice for corrosion protection in the offshore and marine industries.
The following chart ‘Plasmet ZF after Cathodic disbondment‘, displays the results achieved by Plasmet ZF after cathodic disbondment, seawater immersion and cyclic ageing tests. Visual inspection of the coated sample plates showed no blistering, rusting, cracking and flaking and no chalking – you really can’t get better results than that!
“Plasmet ZF and many other Corrocoat systems have for years been used in demanding energy applications throughout the world,” says Sales Director – Rob Cole. “The NORSOK test results give us unbiased confirmation of its performance and our customers an added level of confidence that it will meet their toughest requirements.”
