  • Method of improving the surface of steel pipe for corrosion resistant coating and apparatus for use in carrying out the method
    Patent number: 5371972
    Abstract: Surface anomalies on pipe are removed preparatory to corrosion coating. The removal is conducted by brushing with wire brush elements or Comax brush elements which may rotate about axes parallel to the pipe axis or substantially radially off the pipe. Both kinds of brush elements may be used in combination. Before subjecting the pipe to brushing, the surface is particulate blasted to remove ferric oxide and better expose surface anomolies. After wire brushing, the surface is again particulate blasted to provide an anchor pattern of indentations promoting adhesion of the coating.
    Type: Grant
    Filed: February 7, 1994
    Date of Patent: December 13, 1994
    Assignee: Shaw Industries Ltd.
