WebSome water systems use soil resistivity to determine the type of pipe to install. If soils resistivity is greater than 5,000 ohms/cm (measure of electrical resistance per centimeter), serious corrosion is unlikely, and ductile iron or steel pipe could be used. If resistivity is less than 500 ohms/cm, the potential for corrosion is greater. WebDuring the steel making process, natural low energy iron ore is refined into metal. This process adds a great deal of energy to the metal. Once the steel is placed into a corrosive environment, it will, by natural means, return to its low energy state over time. To make the return trip, the steel must give up the energy gained at the mill.

Web2 feb. 2024 · Resistivity ρ, unlike resistance, is an intrinsic property of a material.It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω × m).The higher the resistivity is, the more difficult it is for the current to flow through a wire.
