What type of system is head pressure testing used on?

Head pressure testing is specifically used in gravity flow systems. This testing method assesses the integrity of the piping and the system’s ability to handle the pressure exerted by a column of fluid due to gravity. In gravity flow systems, the flow of fluid is primarily influenced by gravitational forces, making it crucial to ensure that the system can support the head pressure without leaks or failures.

In contrast, other systems like singleflow and twin flow may not rely on gravitational pressure in the same manner, and high flow typically involves conditions where other forces or pressures are at play that are not primarily gravity-based. Therefore, the focusing on head pressure is directly relevant to evaluating the performance and safety of gravity flow systems specifically.
