What is the purpose of weep holes in flow systems?

Weep holes serve an essential function in flow systems by preventing the accumulation of liquids in gas lines and gases in liquid lines. This is crucial for maintaining the integrity of the flow system and ensuring that it operates efficiently.

When a gas line is in contact with liquid, it can lead to pressure build-up, which may cause operational issues, including potential leaks or failures. Conversely, if gas were to accumulate in a liquid line, it could disrupt fluid flow, leading to inefficiencies or the possibility of equipment damage.

Inclusion of weep holes allows for the release of any unwanted fluids or gases, thus maintaining the intended direction and type of flow in the lines. This is particularly important in systems where phase separation of fluids and gases is required for proper operation, enabling them to function without interference from the other phase.
