Abstract: A method of assessing airframe corrosion risk includes determining a component corrosion stress based on data from at least one of a corrosivity sensor, an aircraft exposure history, a climate database, or an aircraft configuration. The method includes generating a component corrosion risk based on the determined component corrosion stress. An accumulated component corrosion risk is calculated based on the component corrosion risk and a historical component corrosion risk. An airframe corrosion risk is determined based on the accumulated component corrosion risk.

Abstract: The molecular weight distribution in a polymer sample can be used as a measure for when parts need to be replaced, and can be tracked over time to allow for predicting when parts need to be replaced and/or identifying the type of aging taking place in the polymer part. Molecular weight distribution determination has particular application in determining the replacement time and or aging parameters in polyamide (e.g., formed from 11-aminoundecanoic acid or formed from 12 aminododecanoic acid) polyvinyldiflouride, and polyethyelene pipe liners used in, for example, offshore oil and gas production and fuel transport operations.

Abstract: Disclosed herein is a method including: performing eddy current testing on a steam generator tube material by using a motorized rotating pancake coil (MRPC) probe, evaluating a test signal measured using the eddy current testing, and predicting the corrosion rate of the steam generator tube material from a noise value in the MRPC inspection signal of the steam generator tube obtained from the evaluating.When the prediction method of a corrosion rate of a steam generator tube according to the present invention is used, the steam generator tube material which has low corrosion rate can be selected at the material selecting step because the corrosion rate can be predicted and the criterions on the corrosion rate of the steam generator tube can be established as the requirements through an eddy current MRPC noise inspection of the steam generator tube material.

Abstract: A corrosion detection system and a method for operating a corrosion detection system are provided. The system, may include, but is not limited to, a PCB, a corrosion sensor, a first, second, third and fourth standoff coupled between the PCB and a chassis, a constant current circuit coupled to the first standoff, a first trace coupled between the third standoff and a first input of the corrosion sensor, and a second trace coupled between the fourth standoff and a second input of the corrosion sensor, wherein the corrosion sensor is configured to output a signal proportional to the resistance of the chassis based upon a voltage induced at the first input and the second input, and a processor configured to receive the signal proportional to the resistance of the chassis and determine a corrosion level of the chassis by comparing the signal to reference data stored in memory.

Abstract: A method of optimizing system parameters in a crude unit to reduce corrosion and corrosion byproduct deposition in the crude unit is disclosed and claimed. The method includes measuring or predicting properties associated with the system parameters and using an automated controller to analyze the properties to cause adjustments in the chemical program to optimize the system parameters. Adjusting the system parameters effectively controls corrosion in the crude unit by reducing the corrosiveness of a fluid in the process stream and/or by protecting the system from a potentially corrosive substance. System parameter sensing probes are arranged at one or more locations in the process stream to allow accurate monitoring of the system parameters in the crude unit.

Abstract: An apparatus is for detecting corrosion in an internal pipe bore in a pipeline. A tracer chamber containing a first tracer is formed in a portion of the pipeline and is bounded towards the internal pipe bore by a chamber wall having a first corrosion resistance and including at least one wall portion with a second corrosion resistance, the second corrosion resistance being smaller than the first corrosion resistance. A method is for detecting corrosion in an internal pipe bore in a pipeline.

Abstract: A test coupon package suitable for a cathodic protection system includes a native test coupon and first and second active coupons. The active coupons may be biased with respect to the soil or other electrolytic medium in which a pipeline protected by the system resides. The first active coupon may have a surface area that will contact an electrolytic medium that is approximately equal to a surface area of the native test coupon that will contact the electrolytic medium. The surface area of the first active coupon may be substantially greater than a surface area of the second active coupon that will contact the electrolytic medium. The test coupon package may include an electrochemically stable reference electrode positioned between the first active coupon and the native coupon. The test coupon package may be substantially cylindrical and, in at least one embodiment, may include a conical nose connected to a first end of the test coupon package with the second active coupon attached to a narrow end of the conical nose.

Abstract: The coating monitoring system is based on electrochemical impedance spectroscopy (EIS). The system consists of one or more compact and rugged mini-potentiostat modules coupled to one or more electrodes mounted on top of the paint coating of the structure being monitored. The electrodes and modules can be coated with a topcoat if desired. Alternatively, they may be mounted only temporarily to the structure for spot inspection. They periodically report to a laptop. Communications may be implemented using a wireless protocol. The units may be battery powered with an estimated battery lifetime of up to ten years, depending on the frequency of measurement and interrogation Alternative power supplies may be used to replace or supplement the battery to allow extended battery lifetime. Moisture, humidity, or other sensors may be incorporated into the coating monitor.
