What can be used to generate necessary pressure if a pump with adequate head pressure is not available for a pressure test?

• A. Compressed air.
• B. Bottled gas, such as nitrogen.
• C. Water displacement.
• D. Steam injection.

Answer: (B)

Utilizing bottled gas, such as nitrogen, to generate the necessary pressure for pressure testing is a common practice in situations where a pump is not available with adequate head pressure. Nitrogen is an inert gas, meaning it does not react with the materials being tested and can safely bring the system to the desired pressure level. Its use is also advantageous because it can be precisely controlled, allowing for accurate pressure settings without introducing moisture or other contaminants that could result from the use of water or other fluids. In addition, nitrogen is non-flammable and helps to prevent the risk of explosion or fire, which is a significant consideration in many industrial and maintenance environments. Using bottled gas for pressure testing can also facilitate quicker setup and teardown times compared to other methods, making it efficient for various testing scenarios. While other methods may be viable under certain conditions, they each have significant drawbacks. For example, compressed air can be hazardous and is less often recommended due to the potential for the formation of a flammable mixture if there is any residual contamination in the system. Water displacement is typically not used for pressure testing the integrity of piping systems, as it can introduce water into areas where it should not be. Steam injection can create additional risks, including burns and superheating, and
