Design of Buried Steel Pipe

The purpose of this guide is to develop design provisions to evaluate the integrity of buried pipefor a range of applied loads. The provisions contained in this guide apply to the following kindsof buried pipe:* New or existing buried pipe, made of carbon or alloy steel, fabricated to ASTM or APImaterial specifications.* Welded pipe, joined by welding techniques permitted by the ASME code or the APIstandards.* Piping designed, fabricated, inspected and tested in accordance with an ASME B3 lpressure piping code. These codes are: B3 l . l power piping, B3 l .3 process piping, B3 l .4liquid hydrocarbon pipelines, 831.5 refrigeration piping, 831.8 gas transmission anddistribution piping, B3 l .9 building services piping, B3 l. l l slurry piping, and ASMEBoiler and Pressure Vessel Code, Section ill, Division 1 nuclear power plant piping.* Buried pipe and its interface with buildings and equipment.
