<p>The invention relates to a system for detecting the defects of a wall used for enclosing a space where-generally liquid-materials are stored, with a coating on its internal side, especially a container wall, or/and the defects in the coating. In numerous fields of life all types of different materials, such as chemicals, solvents, petroleum oil and petroleum fractions, etc. need to be stored in a way excluding the possibility of these materials getting into the environment or other materials from the environment intermixing with the stored materials. In most cases such materials are stored in containers made of different materials, mostly metal, the walls of which holes may appear either as a result of corrosion or other damage, and through the appearing holes materials can flow either from outside into the container or from inside the container into the environment, and so the stored material may become unsuitable for use or serious environmental pollution may occur. In the interest of damage prevention different monitoring systems are used to detect holes appearing in container walls as soon as possible.</p> |
