GB/T 31405-2015 "Test method for high-temperature cathodic disbondment of pipeline corrosion resistant coatings" is applicable for comparative testing of the cathodic disbondment performance of external anti-corrosion coatings on buried pipelines under high-temperature operating conditions. The core instruments include a high-temperature solution immersion device, a cathodic protection power supply system, and dimensional measurement tools. By simulating high-temperature environments and cathodic protection conditions, the disbondment process of anti-corrosion coatings is accelerated, and the disbondment area or equivalent circle diameter is measured to evaluate the corrosion resistance reliability of the coating.
