What are the common signs of conduit corrosion?

The signs of conduit corrosion typically manifest as flaking, discoloration, or visible rust on metallic conduit. This is because corrosion often occurs when moisture interacts with the metal surface, leading to oxidation which visibly alters the appearance of the conduit. The presence of rust is a direct indicator that corrosion is taking place, while flaking suggests that the surface material is deteriorating as a result of this chemical reaction.

Visible signs like these are critical for maintenance and safety, as they can help identify problems before they lead to significant structural failure or electrical hazards. Observing such indicators allows for timely intervention, whether through repair or replacement, ultimately enhancing the reliability of the conduit system.
