New Float Coat Protects Tanks and Pipelines Against Seawater

Cortec® M-645 is an anti-corrosion additive specially developed for use in seawater and brine applications where a more effective and environmentally suitable float coat is required. Utilizing new patented chemistries, Cortec® M-645 Float Coat is biodegradable, nitrite and amine free, and environmentally acceptable for use. It is approved by the EPA for discharge in seawater. M-645 quickly degrades and is harmless to aquatic, marine, birds or other animal life.

The new and enhanced M-645 Float Coat can be used in coastal and marine applications for ships, barges, offshore oil rigs, tanks, pipelines, pumping stations, refineries, and power plants etc. It effectively stops corrosion in ballast tanks, "Tank Footings on Jack-up Rigs", void tanks, pipelines and complex piping systems. The product provides multi-metal protection and is not affected by salt concentrations. Additionally, it offers protection against atmospheric corrosion. M-645 can be used in both saltwater and fresh water environments.

The product is simple to use and works very much like its name implies, as a float coat. As an example, a ballast tank would be pumped down and pressured washed. After removing foreign material from the bottom of the tank, M-645 would be added. Then as seawater is added to the ballast tank, it floats the M-645.

This floating process coats every square inch of the tank's interior including ring stiffeners, girders, piping  and side shell to protect against corrosion. When tanks are only partially filled, the rest of the tank can be sprayed or brush coated as needed. This same simple process is used to protect production platforms, semi-submersible, fixed platform columns, and even the interior of ship rudders.

Unlike old float coats, the new Cortec® M-645 is nonflammable and allows equipment protected by M-645 to be welded. When a tank, pipeline, or column requires repair involving welding, the M-645 does not present any flammability issues and does not produce toxic fumes.
