What should underground metallic piping be protected against based on soil conditions?

Underground metallic piping is particularly susceptible to corrosion due to various environmental factors present in soil conditions. Soil can contain moisture, salts, and other chemicals that create electrochemical processes conducive to corrosion. When metals are exposed to these elements, particularly when they are in an electrolyte-like environment (moist soil), they can deteriorate over time, leading to leaks or failures in the piping system.

To combat corrosion, protective measures such as coatings, cathodic protection, or the use of corrosion-resistant materials are often implemented. These methods help prevent the metal surfaces from coming into direct contact with corrosive elements in the soil, thereby extending the lifespan and safety of the underground piping system. Understanding the need for corrosion protection is essential for maintaining the integrity of infrastructure that relies on underground metallic piping, especially in varying soil conditions.
