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.
