In what scenario would you use a weep hole in a gas line?

A weep hole in a gas line serves a critical function in preventing the accumulation of liquid within the line. This scenario typically arises in gas pipelines where condensation can occur due to changes in temperature and pressure. If liquid were to accumulate, it could lead to operational issues, such as blockages or inefficiencies in gas flow, as gas is designed to travel in a vapor state.

By incorporating a weep hole, any liquid that may form can escape rather than build up. This design helps maintain the integrity and efficiency of the gas line's operation, ensuring that the gas continues to flow effectively without interference from accumulated liquids. The presence of the weep hole is crucial in systems where condensation is a risk, as it promotes the safe and efficient transport of gas.
