Pipe Line Corrosion and Cathodic Protection: A Field Manual Book by Edward G. Peattie and Marshall Parker
A pipe line buried in the earth represents a challenge. It is made of steel—a strong, but chemically unstable, material—and is placed in an environment which is nonuniform, nonprotective, and nonyielding. It is the duty of the corrosion engineer to study the properties of this system to ensure that the pipe line will not deteriorate. […]
