Abstract: A system and method is claimed for protecting sections of a buried utility pipe that will eventually be excavated and exposed for tapping purposes. The system includes a protective collar that is applied to the utility pipe before the utility pipe is buried. When the utility pipe is to be tapped, the utility pipe is excavated directly above the protective collar. The presence of the protective collar provides a physical barrier that prevents the utility pipe from being damaged from the excavating equipment. When the protective collar is removed, a clean, unobstructed area of utility pipe is exposed on which a tapping procedure can be performed.
