Abstract
Electrically conductive paths are positioned in and extend transversely across the width of the backing of strips of wrapping material. The electrically conductive paths provide means for conducting electrical current through spirally wrapped protective materials from the surrounding earth to voids formed adjacent the overlapped edges of the wrapping material and thus permit cathodic protection for pipe surfaces exposed to voids formed as a result of improper application or bonding failures of the wrapping material.
