The present invention discloses a method and system for conducting high temperature corrosion tests on metallic alloys without the need for extensive laboratory equipment and attendant safety measures through the use of a two-compartment ampoule where a vestibule connects these two compartments. A pre-selected mixture of salts is placed in one compartment in order to generate a specific partial pressure of halogen gas; and a metallic alloy is placed in the other compartment. The ampoule is then heated to a pre-determined temperature and held at this temperature for a pre-determined time period. A halogen gas of a specific partial pressure is thereby generated from the mixture of salts which comes into contact with the metallic alloy. Because the ampoule creates a sealed environment, the metallic alloy is under constant halogenation during the pre-determined time period. The metallic alloy is removed for examination when the pre-determined time period expires.

A housing cladding module for a medical device is provided for collision identification. The module includes resistor elements, which are arranged in and/or on the surface and which are designed such that the resistor elements change their electrical resistance on expansion. The resistor elements are arranged in such a way that the resistor elements are expanded in the event of a collision with an object. The collision is identified easily, and the effective collision force may be ascertained.

A method for inhibiting corrosion of a corrodible metal surface that contacts water in a water system is provided. The method may include introducing into the water a treatment composition including an ex-situ halogenated triazole compound in an amount sufficient for inhibiting corrosion. A method of measuring a concentration of the ex-situ halogenated triazole compound in water in a water system is also provided. The method may include inducing the halogenated triazole compound to fluoresce and measuring an intensity of the fluorescence emitted from the water to determine the concentration of the halogenated triazole compound in the water. The concentration of the halogenated triazole can be monitored and controlled. The concentration of the halogenated triazole can be adjusted to a desired level based on the measured fluorescence value.

Measurement data including data of a sand production rate from a sand metering sensor, pressure data from a pressure sensor, and data of a metal loss value from a metal loss sensor is obtained. A maximum sand erosional velocity ratio and a pressure drawdown are determined. An optimum choke valve setting is determined based on a predefined correlation between the sand production rate, the pressure drawdown, and the maximum sand erosional velocity ratio, in response to determining that the maximum sand erosional velocity ratio is not within a predetermined maximum sand erosional velocity ratio limit. An updated pressure drawdown produced by the determined optimum choke valve setting is within a predetermined pressure drawdown operating window. The surface choke valve is set based on the determined optimum choke valve setting. The well is shutdown by triggering an emergency shutdown device in response to determining that the obtained metal loss value has reached a predefined metal loss limit value.

A computer-based corrosion/erosion module, communicatively coupled with a probe, estimates corrosion/erosion rates in a pipeline based on metal loss measurements. A High Integrity Protection System (HIPS), upstream of the corrosion/erosion module, includes at least two pressure-sensing elements, connected to the pipeline, for capturing pressure readings associated with inside pressures of the pipeline. The HIPS also includes at least two final elements configured to stop a flow of fluid through the pipeline. A logic solver, coupled with the corrosion/erosion module and the HIPS, is configured to automatically monitor mechanical integrity of the pipeline in real time using the captured pressure readings and estimated metal loss measurements. The logic solver determines a trip set point adjustment using the estimated metal loss measurements and provides the trip set point adjustment to the final elements.
