The choice of 180°C (or approximately 356°F) as a common upper limit in testing corrosion inhibitors for oil and gas applications can be attributed to several practical and technical considerations:
Simulation of Downhole Conditions: Many oil and gas reservoirs have temperatures that do not exceed 180°C. Testing at this temperature allows for the simulation of real-world conditions where corrosion inhibitors are expected to perform. Although some reservoirs might be hotter, a significant portion falls within this temperature range.

Material Limitations: Many materials used in oilfield equipment (like carbon steel, which is common in pipelines and casings) degrade significantly above 180°C. Thus, testing inhibitors at this temperature helps understand their effectiveness under conditions where these materials are typically used without the added complexity of material degradation from higher temperatures.
Equipment Constraints: The equipment used for testing, such as autoclaves, typically has a safe operational limit around this temperature. Beyond this, the equipment might require special modifications for safety, pressure ratings, or material compatibility, which increases costs and complexity.

Chemical Stability: At higher temperatures, the chemical stability of both the inhibitor and the corrosive environment can change. Inhibitors might decompose or react differently at temperatures significantly above 180°C, potentially altering the test results in ways that do not reflect normal operational conditions.
Standardization and Comparability: By setting an upper limit like 180°C, it provides a standardized condition across different tests and labs. This standardization allows for more comparable results among different inhibitors or when testing is repeated by different entities.

Economic Considerations: Higher temperatures require more energy for heating, more robust containment systems, and can lead to faster degradation of test equipment or samples. Testing at 180°C offers a balance between getting meaningful data and maintaining cost-effectiveness.
Safety: Working with corrosive substances at high temperatures involves safety risks. The 180°C limit helps manage these risks while still providing valuable data on inhibitor performance.

Relevance to Common Applications:Most oilfield corrosion inhibitors are designed for environments where temperatures do not exceed this limit frequently. Thus, testing at 180°C is often sufficient to cover the majority of operational scenarios.
