... of diagnostic work to evaluate the results; Recommendations for maintenance of pipelines. Safety of operation, exclude leakage and contamination of environment, reduce hazards of fire and explosion. The methodology approaches the problem from a new perspective. The stress from spatial position...

...Abstract Contamination of blast cleaned steel surfaces prior to application of protective coatings leads to premature coating failure resulting from corrosion. It has become common practice to include a salt contamination test prior to the application of the first coat to ensure the required...

.... EVALUATION To determine the suitability of these lining as a replacement for the existing coatings, their compatibility with the service fluid was evaluated (chemical resistance as well as potential for fluid contamination) and the economics were evaluated based on projected useful life. The service fluid...

... important properties of a concrete surface as it relates to a bonded coating. Just as important, there is no standardized method for identifying contaminants and qualifying the removal of contaminants. But most importantly, unlike steel, there are no precise guidelines on what is required of the concrete...

...CLASSIFICATION OF CONTAMINANTS Contaminants may be grouped according to their sources, symptoms, or cures, but strict classification according to any one such quality causes duplication in discussing the other two. We have therefore used hybrid classifications to divide the contaminants into four...
