Las Cruces Utilities fights gas line corrosion

Every pipe put in the ground can face damage, like rainwater shifting dirt and a line being punctured by rocks. However, steel gas lines face other challenges; they can corrode with rust over time. There are specific sacrifices involved in maintaining the lines – in this case, it’s another chunk of metal, called a sacrificial anode, that takes the heat for corrosion instead of the gas line. Similar to what might be found in a home’s water heater, these sacrificial anodes are designed and placed to protect gas lines, along with specific coating on the pipes themselves that protects the steel from the corrosive effect of the soil.
