What must be done before applying a patch to a pipe?

Before applying a patch to a pipe, ensuring that the patch is clean is essential for several reasons. A clean surface allows for better adhesion of the patch material, increasing the effectiveness of the repair. Dirt, grease, or other contaminants can interfere with the bonding process, leading to potential failure of the patch and allowing further leakage or damage. This step is crucial in both temporary and permanent repairs, as it lays the foundation for a successful sealing.

In addition, while achieving a clean surface is vital, drying the surface is equally important, as moisture can compromise the adhesion. However, focusing on the cleanliness of the patch itself highlights the direct relationship between the state of the patch and the success of the repair. Such attention to detail is a fundamental principle in damage control practices, ensuring that maintenance is performed to the highest standard.
