Cortec Offers Corrosion-Control Solutions for Vessels Containing Saltwater or Brine
ST PAUL, MN — Marine environments are extremely aggressive and corrosion protection in these areas requires an especially careful approach. Application of VpCI® inhibitors in the hydrostatic testing process is important since the test water can be aggressive to pipeline material. The same goes for seawater ballasting of ships. M-645 is a float coat used to inhibit corrosion in vessels containing saltwater or brine. It floats on the surface of the water, forming a self-healing protective film on adjacent metals.
The film displaces water containing chlorides from the surface of the vessel. As the water is raised or lowered, M-645 coats every square inch of the vessel’s interior— including ring stiffeners, girders, piping, and side shells—with a sufficient amount of product to protect against corrosion. M-645 is ideal for ballast tanks that are frequently emptied and refilled. Because M-645 floats on the surface of the water, the non-aqueous formula does not contaminate ballast water, allowing for normal discharge procedures. It is also an effective corrosion inhibitor for hydrotesting large aboveground storage tanks (ASTs). The product is non-hazardous, non-flammable and self-reapplying. It will provide corrosion protection for a broad range of saltwater/brine applications. M-645 extends ballast tank life, minimizing costs for dry docking repairs, and does not interfere with ballast water discharge. It is effective for multiple tank refills. Applications include hydrostatic testing of pipelines, vessels, and ASTs and seawater ballasting of ships, buoys, and oil rigs.
