    Abstract: A method to assess external corrosion in buried pipelines includes analysis of moisture content of soil along the length of the pipe to choose the most appropriate indirect inspection methods. External corrosion is assessed based on the unification of probability techniques using clustered inspection data and deterministic formulation for soil conditions. A deterministic model pinpoints the location of the most likely areas for corrosion due to the electrochemical cell formation produced by the presence of water and the properties of the soil, such as ion concentrations, pH, soil resistivity, redox potential, corrosion potential and soil type. The filtering of the data by clustering provides reliable results to locate the most corrosive locations. The failure probability is calculated based on in-line inspection data, where different indications could appear and different dimensions are used to link the corrosivity with the failure for choosing repairing methods and taking actions against corrosion.

    Abstract: The present invention is directed to a corrosion resistance evaluator suitable for corrosion testing coated metals substrates, such as auto bodies at an accelerated rate. A corrosion resistance evaluator provided with a chamber containing electrolyte to which anode and cathode coated with protective coating being tested are exposed. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages modulated in triangular, truncated triangular or trapezoidal manner for preset durations that are interspaced with recovery periods. The impedance date collected is then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).
