In this work, several studies of aging pipes have been compiled and, starting on the basis of circulating flow through a pipe of t years of age is based on the inner diameter and driving age, some design life tables have been made corresponding to the main materials and components of pipes specifically: iron, steel, concrete, fibre cement and plastics, determining the corresponding ageing by multiple linear regression equations, obtained for all these materials. Several proposals of analytical configuration of the mathematic functions of aging (flow-time) that can be useful for the study and prevention of this phenomenon are also made.
