In which scenario would salt water be least likely used as a pressure test medium?

• A. For copper lines.
• B. Austenitic steel lines.
• C. High-chloride environments.
• D. Plastic piping systems.

Answer: (B)

The use of salt water as a pressure test medium is particularly concerning when considering the materials involved and their susceptibility to corrosion. Austenitic steel lines, while generally resistant to corrosion, can be vulnerable in specific conditions, especially in high-chloride environments that salt water introduces. Salt can lead to pitting and crevice corrosion in stainless steel, reducing the integrity of the material over time and compromising the effectiveness of the pressure test. In contrast, the other scenarios present different considerations. Copper lines might be less susceptible to the effects of salt water than stainless steel, but they can still corrode under certain conditions. High-chloride environments are directly related to salt water, so using it there would naturally be less favorable. Plastic piping systems, on the other hand, generally have good resistance to saltwater corrosion and are often tested with it without significant risk. When evaluating the materials’ compatibility with salt water, the potential for damage due to corrosion is a critical factor, making austenitic steel lines the least desirable for testing with salt water.
