What is a commonly used method for repairing a small leak in a pipeline?

A commonly used method for repairing a small leak in a pipeline is sealing it with a box patch. This method provides a more durable and effective solution compared to other options. A box patch involves cutting a piece of material that is slightly larger than the leak and securing it with bolts or clamps over the area. This creates a strong seal that can withstand the pressure of the fluid within the pipeline, preventing further leakage and potential damage.

Using tape, while it may provide a temporary seal, is generally not reliable for long-term fixes on pressurized systems, as adhesive can degrade and fail. Inserting a wedge into the hole does not create a proper seal and can lead to more complications by not addressing the source of the leak. Ignoring the leak until major repairs can be made is not a safe practice, as it risks worsening the situation over time and could lead to catastrophic failures in the pipeline system. Thus, sealing with a box patch is the most effective and widely recommended method for small leak repairs.
