91-14: Update on White Rust Corrosion and Control Fills The ISO 9001 quality system

The ISO 9001 quality system presents an outline/philosophical approach for formalizing the quality system function within the manufacturing organization that does not interfere with the normal business operation

91-14: Update on White Rust Corrosion and Control Fills The ISO 9001 quality systemThe problem of "white rust" of galvanized steel cooling towers is defined. The available published literature is reviewed briefly. Laboratory work designed to determine the impact of several chemical and physical parameters are described. The nature of the protective layer which forms on galvanized steel surfaces in contact with different chemical environments is described. A generic procedure to minimize white rust in new galvanized cooling towers is
