SolutionsMarine Riser in the Splash Zone and Tidal Zone
Marine environment consists of five parts: marine atmosphere zone, splash zone, tidal zone, full immersion zone, marine mud zone. It is indicated that the steel structure in the splash zone is the most likely to corrode. In the tidal zone, the tidewater will rise and fall and the alterations of wetting and drying will lead to quick corrosion especially near the high tide level and low tide level. What’s worse, the special environment in the splash zone and tidal zone makes it more difficult to prevent the corrosion.

Zhejiang Yuxi develop a piece of cathodic protection device for marine riser to solve the corrosion in the riser and platform piles.
