What is a suitable action for controlling a small leak in a pipe?

Using a clamp is an effective immediate solution for controlling a small leak in a pipe. Clamps can provide a temporary fix that helps to seal the leak until a more permanent repair can be conducted. They work by applying pressure around the pipe at the leak site, which helps minimize or stop the escape of fluid or gas. This method is particularly useful in situations where it is critical to maintain system pressure or fluid flow temporarily.

In contrast, increasing the gas pressure could exacerbate the leak, causing more damage and increasing safety risks. Reducing flow to zero might not be feasible if the system relies on continuous operation, and simply leaving the leak unattended could lead to further complications, including potential hazards or significant damage over time. Therefore, the use of a clamp is the most practical and immediate response to manage a small leak effectively.
