Tackling corrosion of internal voids

Louise Smyth

Despite so many advances in technology, industry still faces the age-old problem of corrosion. Much time and money are poured into preventing rust or trying to remedy its consequences. A major question that remains is how to protect complex internal cavities and voids that are difficult to access and create a breeding ground for undetected corrosion. Often, these voids involve structural steel or high-value equipment modules. Once corrosion takes place within, it can be difficult if not impossible to undo the damage. The extreme value and critical nature of many of these assets make it incredibly important to prevent this from the outset. Fortunately, Cortec’s new CorroLogic Fogging Fluid VpCI-339 makes an already simple and effective method of corrosion protection even more convenient than before.

The new solution is a ready-to-use 100% vapour phase corrosion inhibitor (VpCI) product for preservation of void spaces comprised of multi-metals including mild carbon steel, stainless steel, cast iron, aluminium, copper and galvanised steel. VpCIs migrate throughout the voids to protect metal surfaces, even in hard-to-reach areas, resulting in time and cost savings. The product is water and hydrocarbon soluble and leaves no solid residues. It is nonflammable and free of chrome, phosphorus, halogen and silicon elements. It is user-friendly and contains no EPA or OSHA hazard. It is also free of HAP (hazardous air pollutants).

Cortec’s new CorroLogic Fogging Fluid VpCI-339 comes ready-to-use and can be applied by fogging or misting at a very low concentration into voids such as pipes, tanks, containers, boxes, crates, and shrouded packages. The fogging fluid is fast-acting, forming a thin, self-healing protective film on metals inside the enclosed space. It is an excellent anti-corrosion solution for: complex internal cavities; double wall spaces; pipes, heat exchangers and modules; and transportation and deep storage of key assets.
