摘要： A shaft wall pressure corrosion test system includes a pressure bearing device, a confining pressure application device, and a seepage pressure application device. The confining pressure application device and the seepage pressure application device provide confining pressure and seepage pressure for the pressure bearing device, respectively, and keep the confining pressure and the seepage pressure constant on the pressure bearing device. In the system, axial pressure is applied to a piston by means of a hydraulic jack and is then transferred to a sample to complete axial pressure application. The confining pressure is applied to hydraulic oil by a manual pump in combination with an energy accumulator and then transferred to the sample to complete confining pressure application. The seepage pressure is applied to a corrosion solution by a water pump group in combination with an energy accumulator and then transferred to the sample to complete seepage pressure application.

摘要： A test device includes a thermostatic tank, a heater, a rotary sample stage, a black panel thermometer, a light source, an in-tank thermometer, a sprayer, and a controller. The sprayer sprays water to samples placed on sample placement units of the rotary sample stage and the black panel thermometer. Mist droplets of mist sprayed by the sprayer are set in a range in which a decrease in temperature of the samples and the black panel thermometer irradiated with light is suppressed by spraying to the samples and the black panel thermometer.

摘要： A test sample of a vulcanized rubber material is placed under a preset placement condition in a fixing frame in a test tank having a predetermined ozone concentration, and digital image data is acquired by capturing at a fixed point, over time, with at least one camera device, images of a surface of the test sample that has been placed in the test tank; and determining a change in a surface state of the test sample between a plurality of points in time by analyzing, with a computation device, the image data that has been acquired. Such evaluation method for evaluating ozone deterioration of a vulcanized rubber material can accurately determine a change over time in ozone deterioration while reducing working man-hours.

摘要： Apparatus and methods for automated corrosion testing are disclosed. The apparatus and methods afford an integrated corrosion testing system that allows input of testing parameters for testing of specimen including temperature, pH, salinity, and/or chemical composition of a testing solution (e.g., a customizable testing solution), flow rates of the solution, parameters for cyclic immersion of the specimen into the testing solution, and time of testing. The system is automated to perform corrosion testing according to the input parameter including constant monitoring of the system to ensure the parameters are met including ensuring the desired testing solution characteristics are maintained with little or no user input.

摘要： A system for measuring corrosion and corrosion-erosion rates in a high temperature, high pressure multiphase dynamic environment includes a plurality of ring-shaped test coupons disposed within a test vessel in a vertical arrangement relative to one another. A test fluid mixture is added to the vessel and the temperature and pressure are maintained such that the mixture exists in a multiphase condition that has a vertical stratification such that each test coupon is exposed to a different phase and/or combination of phases of the fluid. Impellers can be used to stir the fluid to provide a dynamic environment. The fluid can include particulate matter to simulate real world test conditions. Separator plates can be disposed at different vertical locations within the vessel to maintain separation between various phases of the fluids and further restrict particulate matter from migrating between sections of the test system.
