- Abstract
- This report is the result of a thorough survey of the literature on underground water pipes. It aims to establish a static 'failure matrix methodology.' Most of the data and examples are limited to cast-iron pipes of diameters between 4 inches and 36 inches under static conditions. A general description of a typical pipeline network is presented, with particular emphasis on its geometric configuration and physical characteristics. Strength properties of typical pipeline materials and the materials used in their joints are described. A resume of test data on pipeline joints is given, along with a correlation of the test data with the results of elementary theory. Standard pipeline design methods also are described. Typical pipeline modeling data are presented and needed typical entries for a static 'failure matrix' are derived. The 'failure matrix' establishes failure characteristics for various types of pipelines, depending on their geometric configuration, their materials, the materials of their joints, and their support, operating, and loading conditions.
