External pressure design of large-diameter piping: Optimal analysis approach

Large-diameter piping used in the petrochemical, oil and gas, steel plant and power industries often carry toxic fluids and can pose significant safety hazards.

Large-diameter piping used in the petrochemical, oil and gas, steel plant and power industries often carry toxic fluids and can pose significant safety hazards. Their stability and reliability are important while they operate under external pressure loading due to vacuum formation or any other external load that can potentially collapse the piping system. Major piping codes, such as the ASME B31 pressure piping series1, refer pressure vessel codes for the design of piping subjected to external pressure. However, piping and pressure vessel configurations are usually different, and a pressure vessel external pressure design approach should be carefully considered when applied to piping. In th
