Could you please provide the formulas used in AutoPIPE for pressure elongation of a straight pipe (assuming pipe is free to expand). I am using ASME B31.3 and CSA Z662 codes.Model has 2 different analysis sets, but the support loads dues to GR(1) and Gr(2) are different, why?Text Answer: Go through the following link: http://communities.bentley.com/products/pipe_stress_analysis/f/275801/p/40611/89583.aspx#89583 AutoPIPE uses thick wall formula for calculation of pressure extension.
