Many plant explosions and accidents are caused by corrosion, erosion issues, or defects in material. Others are due to operational or maintenance problems. Improving analysis and verification will not eliminate these accidents, but the small increased cost associated with improved analysis and verification procedures will reduce overall plant risk associated with overload and stress while reducing cost associated with layout, changes, and unneeded complexity. 

This is an interesting time in the evolution of the ASME B31 codes. Some of the recent changes in the approach to the B31 code’s calculation of Stress Intensification Factors (SIFs), flexibility factors (k-factors) and Sustained Stress Indices (SSIs) hold the potential to significantly impact the safety and economics of future piping designs. In this Hydrocarbon Engineering article, Tony Paulin, PE, president of Paulin Research Group, discusses how the current B31 code approach to bends is not yet addressed by B31J.

However, Paulin Research Group’s FEATools in conjunction with Intergraph’s CAESAR II does address this issue.
