Corrosion Control on Underwater Piles

Foundation piles are structural elements driven to deep and stable soil strata to hold main structures, such as a bridge or a building, in place. They serve as legs where foundations are rested and take form as sub-structures. Foundation piles, therefore, are the most important parts of a building or structure, aren’t they? They are designed to be really tough. But unfortunately, they are also very vulnerable and can crumple because of being exposed to harsh environment? Steel Pipe Piles are the best examples.

corrosion coating on tubular piles

Corrosion has been a huge struggle to many Business Industries and a great challenge to the field of Engineering. National Association of Corrosion Engineers (NACE International) in particular, as the globally recognized premier authority, has been into Corrosion Control Solutions since 1943.

Corrosion cannot be totally eliminated but can be mitigated and controlled to allow structures serve their designed life spans. Corrosion protection and control include the use of inhibitors, surface treatments, coatings and sealants, and cathodic protection. These solutions can be regrouped into a well-designed program that includes the utilization of a high-performance coating system supplemented by an equally well designed cathodic protection system as follows:

painted steel pipes

The most commonly utilized corrosion protection to steel sheet piles and pipe piles, due to their low-cost, high resistance to sea water, oil, and chemicals.

ESC can provide competitive solutions to all types and magnitude of project requirements.

ESC uses internationally recognized coal tar epoxy paint brands and specifications that comply with project specifications around the world. Sand blasting to SSPC10 or NACE No. 2 standards are the norm for ESC products. ESC's SSPC certified paint inspectors ensure quality of the end product's coating through all stages of preparation, application and testing. The standard color of these coatings is black.

Glass Flake Epoxy Coating

Are ideal for applications where there is expected to be impact and high abrasion environments. ESC applies strict quality controls and careful packing to ensure the coating is in pristine condition when the product arrives on your site.

Hot Dip Galvanization

Pipe galvanized with an average thickness of more than 85 micron.

The process of Hot Dip Galvanization involves coating the steel sheet or pipe pile with a layer of zinc. This is achieved by immersing the steel sheet piles in a hot bath of molten zinc. It is considered as an alternative to paint systems and produces an aesthetic shiny surface. ESC has experience and the contacts to apply such systems to steel products.

Duplex Coating System

Painted sheet piles

Duplex coatings consist of a combination of hot dip galvanization and traditional epoxy coating systems.

While it is not a standard application, it might be required on special projects and ESC can offer such solutions.

Is an effective method of corrosion protection. It increases the design life and can be replaced much more easily than reapplication of corrosion protection coatings. It is typically utilized in conjunction with corrosion coatings to form a complete corrosion protection system.

sacrificial anodes installation

It is a sacrificial form of protection where an anode, typically made of aluminium or zinc alloy is bolted or welded to the steel structure. The steel and anode material form a galvanic cell where the anode oxidizes preferentially to the steel, hence reducing or eliminating the rusting of the steel.

ESC has the capability to design, supply, install and commission such cathodic protection systems.
