Understanding Corrosion

Corrosion of Iron and Steel or water or moist outdoor environments is caused by electro-chemical reactions. It is a natural process where the binding energy within the steel atoms is weakened to a point causing more electrons to leave the atomic structure of the metal. Electric current is carried through water by the transport of metal ions. It requires the presence of oxygen, an electrolyte, and conditions that produce anodic and cathodic surface areas on the metal. The anodic reaction (oxidation) represents the acquisition of charges by the corroding metal, while the cathodic reaction (reduction) represents the loss of charges by the hydrogen ions that are discharged. The corrosive metal loss occurs at the anodic regions on the surface of the metal where the passage of current out of the metal is accompanied by the dissociation of ferrous ions.

Corrosion of Piling in Marine Environments

The life of unprotected steel piling in marine installations varies with the conditions of exposure. Wharf or pier construction in protected harbors can be expected to have a considerably longer life than shore structures that are subject to salt spray. Seawater causes more corrosion due to high salt content. Corrosion is highly likely based on the duration of exposure of the steel surface to water and other corrosion-stimulating agents.  The risk of corrosion increases with piles in direct contact with polluted and/or seawater. In marine splash zones, protections can be employed in the form of coatings or concrete encasement.  Protective systems for sheet piling require knowledge of the stress levels and ranges in the product and the conditions of the soil/water in which it is to be driven. 

Dealing with Piling Corrosion

Steel piles and sheet piles in soil and water must remain in place for a long time without corrosion affecting their load bearing capacity. The challenge is to balance the cost of corrosion prevention and the service life expectancy of the piling. The corrosive nature of seawater can damage marine and waterfront structures, destroy their aesthetics or render them unable to support the machinery, equipment or other loads they were designed to carry.

ICC Marine’s corrosion protection products provide a protective barrier to lengthen the life of your assets.

HDPE Jacket Wrap
The Series 100 encapsulates wharf piles, riser pipes and exposed piping in splash and intertidal zones. It accommodates piles with cylindrical and H-Pile configurations, as well as support members, bracing, brackets and other irregular surfaces. The system is ideal for environments where conditions are too severe for paint systems, epoxies and other conventional forms of protection.
