A significant number of repairs (over 60% of all repairs) are performed with a full circumferential pipe repair clamp, with most repairs being performed on 4, 6, 8, 10, and 12-inch diameter ranges. Leaks may be associated with corrosion, pipe impact, freezing, stress, improper bedding, inferior material, and age. The process to repair various types of pipe involves an analysis of the damage, and selecting the best and most cost-effective repair method while minimizing the interruption of service. As part of a comprehensive discussion concerning pipe, many aspects of the repair process must be reviewed.
