Abstract

Procedimento per il monitoraggio del distacco del rivestimento protettivo di condotte od altre strutture metalliche immerse o interrate soggette a protezione catodica, in base alla resistenza elettrica offerta complessivamente dal sistema condotta/rivestimento/terreno, consistente nell'applicazione alla condotta di correnti di eccitazione locali ad onda sinusoidale a diverse frequenze e nella misura delle corrispondenti risposte in tensione, confrontando quindi le risposte misurate del sistema, determinando in base alle differenze o coincidenze di risposta alle varie frequenze se nel tratto considerato si hanno fenomeni di distacco con corrosione in atto oppure di semplice decadimento del rivestimento.
