Abstract
Inventia se refera la un procedeu pentru supravegherea aparitiei coroziuni în conducte si instalatii, destinat echipamentelor industriale prin care circula fosgen sau medii cu continut de fosgen si în care la patrunderea accidentala a apei de exemplu prin schimbatoare de caldura sau neetanseitati se formeaza acid clorhidric care produce o degradare rapida, prin coroziune a acestor echipamente. Procedeul pentru supravegherea aparitiei coroziunii în conducte si instalatii, conform inventiei, consta în masurarea continua a rezistentei electrice printr-o metoda cunoscuta a unui traductor de coroziune montat în curentul de fosgen fie direct pe conducte fie într-un by-pas, realizat dintr-un material a carui viteza de coroziune este mai mare decît cea a materialului "U" avînd o grosime suficienta pentru a nu permite modificarea geometrica acestuia prin circulatia fluidului de lucru etans la exterior fie cu rasini sintetice, fie cu etansari mecanice cu proprietati electroizolante si care la aparitia conditiilor de coroziune prin patrunderea apei se degradeaza si îsi modifica rezistenta sa electrica.
