American Lifelines Alliance. Guidelines for the design of buried steel pipe

July 2001 with addenda February 2005 This report was written under contract to the American Lifelines Alliance, a public-private partnership between the Federal Emergency Management Agency (FEMA) and the American Society of Civil Engineers (ASCE). This report was reviewed by a team representing practicing engineers and academics.The American Lifelines Alliance (ALA) was formed in 1998 under a cooperative agreement between the American Society of Civil Engineers (ASCE) and the Federal Emergency Management Agency (FEMA). In 1999. ALA requested a group of civil and mechanical engineers. listed in the Acknowledgments. to prepare a guide for the design of buried steel pipe.The group prepared the guidelines presented in this report. with an emphasis on the fundamental design equations suitable for hand calculations. and where necessary. guidance for finite element analysis. 1. 1 Project Objective The purpose of this guide is to develop design provisions to evaluate the integrity of buried pipes for a range of applied loads. The provisions contained in this guide apply to the following kinds of buried pipe: New or existing buried pipe. made of carbon or alloy steel. fabricated to ASTM or API material specifications.Welded pipe. joined by welding techniques permitted by the ASME code or the API standards.Piping designed and fabricated. inspected and tested by an ASME B31 pressure piping code. These codes are:
B31.1 power piping.
B31.3 process piping.
B314 liquid hydrocarbon pipelines.
B31.5 refrigeration piping.
B318 gas transmission and distribution pipi g.
B319 building services piping.
B31. 1 1 slimy piping. and ASME Boiler and Pressure Vessel Code. Section III. Division 1 nuclear power plant piping.Bluied pipe and its interface with buildings and equipment.
