  • Fail safe protective wrapping
    Patent number: 9034778
    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.
    Type: Grant
    Filed: July 27, 2007
    Date of Patent: May 19, 2015
    Assignee: Polyguard Products, Inc.
    Inventors: John W. Muncaster, Richard Norsworthy
