Is Mill Tolerance used in Sustained Stress Calculation

Jan 29 2010 0183 32 There is a debate regarding the 125 mill tolerance some say it is due to the misalignment of the mandrel during the pipe forming and if the thickness at one point of the section is less it would be larger on the other point of the section and the modulus effectively remains the same...
