Paperback. Etat : New. Print on Demand. This book presents an in-depth examination of a fractured eight-inch diameter cast iron pipe natural gas main, conducted by the National Bureau of Standards at the behest of the National Transportation Safety Board, following an explosion and fire incident. Unlike today's pipes with uniform wall thickness, the failed pipe exhibited a non-uniform wall thickness, indicating its age and the obsolete pit casting method used in its manufacture. Through meticulous analysis, including documentary photography, chemical analysis, examination of graphitization, metallographic examination, hardness measurements, ring tests, and Talbot tests, the author provides a detailed account of the pipe's material properties, microstructure, and fracture characteristics. The examination revealed that the pipe failed in a brittle manner due to a bending load applied to the unsupported pipe, emphasizing the importance of proper soil support for underground pipelines. This book offers valuable insights into the behavior of cast iron pipes under stress and the significance of maintaining adequate infrastructure to prevent catastrophic failures. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
