Our company carried out anti-corrosion construction of a wave energy device shaped node, and found that there was no great change through the comparison with the newly completed construction photos. The corrosion protection of flanges and other components on wave energy devices must not only withstand the test of high temperature, high salt, high humidity and high ultraviolet radiation in the South China Sea, but also withstand the impact of waves, which is very difficult to prevent corrosion. Oxidation polymerization coated anticorrosive material is soft and easy to fit, has a long protection period, aging resistance, and plays a very good anticorrosive effect on this special-shaped steel structure.
