The electrical survey has been an invaluable tool in the field practice of corrosion control on pipelines. Its practicality for detecting the more aggressive corrosion areas has been well established. However, electrical surveys do have limitations. In spite of these limitations, the electrical survey has been assigned a new role--that of differentiating between no corrosion and active corrosion. This assignment results from the wording of certain federal and state regulations concerning active corrosion. The wording of this segment of these regulations focuses attention on those circumstances under which the electrical survey becomes impractical.
