What requirement is associated with scratches in a pipe?

The requirement associated with scratches in a pipe, particularly when specifying a depth threshold, is important for maintaining the integrity and safety of the pipe. When a scratch on the pipe's surface is deeper than 10% of the pipe wall, it can compromise the structural integrity and may lead to failure, leaks, or other issues under stress or pressure. Therefore, it is essential that these scratches are addressed through proper repair techniques or pipe replacement to ensure the functionality and reliability of the distribution system.

Addressing shallower scratches may not be necessary, as they typically do not pose a risk to the overall structure of the pipe. Consequently, this requirement will help in making informed decisions regarding maintenance and safety protocols in pipeline management.
