Annotation of standard text API TR 593 :

This technical report details pipe span calculations that were performed to determine structural minimum thickness (TSTRUCT) values for various pipe sizes, pressure classes, materials, and temperatures. A large-scale finite element analysis (FEA) sensitivity study was performed to determine if local stresses at pipe supports limit TSTRUCT for any cases. The intent was for the results to be used to update the structural thickness tables in API 574. See more
