GB/T 34677-2017 "Corrosion Protective Coatings for Subsea Production Systems" applies to corrosion protective coatings for carbon steel or stainless steel substrates used in subsea production systems of marine engineering, where the operating temperature does not exceed 50°C. It specifies core indicators such as non-volatile content, adhesion, and cathodic disbonding resistance. The bonding strength of coatings is measured using a pull-off adhesion tester, and pressure-holding cycle tests are conducted through high-pressure testing devices. The standard clarifies the preparation of test panels, test environments, and inspection rules to ensure the corrosion protection reliability and durability of coatings in marine subsea environments.
