Webboperate pipelines at higher stresses. Most pipelines codes around the world limit design stresses to 72% SMYS. However, USA and Canadian pipeline codes allow operation at hoop stresses up to 80% SMYS; but current regulations in the USA limit the stress to 72% SMYS. Therefore, it is appropriate to investigate the reliability, WebbHoop Stresses = 138.726 N/mm^2 Allowable calculation:: = W*E*SH. where: W = 1. E = 1. SH = 137.8951 N/mm^2.
