    摘要: An automated, remote control/monitoring system for a cathodic protection system for a buried metallic object based on monitoring multiple coupon test stations, buried next to the metal object, by a central processor, which can individually control multiple cathodic protection rectifiers. Preferably, the reference for potential measurements is a buried coupon having a metallurgy substantially the same as the metallurgy of the buried object.

    摘要: A coupon for measuring the corrosion rates of metals in a hostile environment, including two or more thin-film resistive conductors formed on a substrate and positioned in close physical proximity so that they are subjected to essentially the same physical environment. One or more of the thin-film resistive conductors is directly exposed to the potentially corrosive environment while at least one of the thin-film elements is protected from the corrosive nature of the environment. The element or elements that are protected from corrosion are either shielded from the corrosive effects of the environment by the presence of a thermally thin protective layer or by being isolated from the corrosive environment while being maintained at essentially the same temperature as the elements exposed to the corrosive environment. The invention is also directed to a system for measuring the corrosion rate by measuring the change in resistance of the exposed conductor in comparison to the protected chamber.

    摘要: A method and system for detecting and preventing Stress Corrosion Cracking (SCC) in buried pipelines or other structures is presented. The basic principle of the invention is to use a plurality of test coupons which are placed in the same environment as a pipeline or other structure of interest as indicators of the development of SCC in the structure of interest. Loading and temperature of the test coupons are controlled. The test coupons are given a range of different Cathodic Protection (CP) levels, with the range of CP levels selected so as to encompass the CP level at which SCC would be expected to occur. The occurrence of cracking in a test coupon indicates levels of CP which will sustain SCC. SCC is prevented in the structure by application of a level of CP which did not sustain SCC.

    摘要: To monitor corrosion in multiphase fluids pipelines, a first pipe is fluidically coupled to extend perpendicularly away from a bottom portion of a multiphase hydrocarbons pipeline. The multiphase hydrocarbons include oil, gas and water. The first pipe is fluidically coupled to a T-shaped pipe subassembly including a second pipe and a third pipe attached to the second pipe to form a T-shape. A hydrocarbon sample of the multiphase hydrocarbons is drawn into the first pipe. Gas in the hydrocarbon sample separates gravimetrically from oil and water in the hydrocarbon sample. The hydrocarbon sample is flowed from the first pipe through the T-shaped pipe subassembly. The hydrocarbon sample is analyzed using a corrosion coupon attached to one end of the third pipe and a corrosion probe attached to another end of the third pipe. A level of corrosion of the pipeline is determined based on results of analyzing the hydrocarbon sample.

    摘要: A system for determining a corrosion level of a pipeline includes a corrosion coupon received from the pipeline, a database, a first computer, a second computer, a neural network, and a third computer. The database includes existing data indicative of corrosion of a plurality of previously analyzed pipelines. The first computer receives corrosion data of the corrosion coupon and uploads the corrosion data to the database. The second computer uploads calculations performed on the corrosion data to the database. The neural network receives the corrosion data and the calculations from the database and outputs a corrosion level of the pipeline based on the corrosion data and the calculations. Further, the neural network is trained on the existing data from the plurality of previously analyzed pipelines so that the corrosion level is based on a combination of the corrosion data, the calculations, and the existing data. Finally, a third computer receives the corrosion level and generates a report of the corrosion level of the pipeline.

    摘要: A method and system for visualizing the effects of corrosion are provided. In the context of a method, a workpiece is interrogated with radiation, such as by interrogating the workpiece with x-ray radiation. By relying upon a radiographic technique, the workpiece may be hidden and may be interrogated without disassembly. The method generates a backscatter image of the workpiece based upon radiation backscattered from the workpiece. The method also compares one or more regions of the backscatter image of the workpiece with respect to backscatter images of different metal loss indicators. Each metal loss indicator is representative of a different amount of metal loss. As a result of the comparison, the method estimates the metal loss attributable to corrosion of the workpiece.
