Temperature Aeration Chlorination Inhibition efficiency Socrates-B also determines the system pH based on acid gas partial pressures, buffering and temperature where it is relevant. In the case of stimulation acids, the system calculates a required pitting index as the measure of environmental severity. The only materials displayed in the results window are those that have a pitting index higher than the computed RPI . Selected materials within a specific class can be displayed by double clicking on any folder, shown below. To view the information for a specific material listed, double click on the name of the alloy.
Material choice is largely dependent on the application.
Material required for tubing may not be suitable for flowline conditions. Any application from tubing, liners, wellheads, surface equipment, flowlines and speciality equipment can be chosen for material selection. For superior resistance to corrosion and environmental embrittlement, lower strength materials are preferable. Socrates-B provides a subclass consisting of different strengths. In some cases, though, materials are specified by hardness in order to limit cracking due to environmental susceptibility.
