    Problem : Tank lifting as per appendix J

    I refer to Par. J.3.8.3 of API650 The required safety factor of 4 is referred to Tensile strength or Yield Strength of material. Why I must double the load acting on a lug ? If a customer require 1.5 or 1.25 I may assume this value or I must assume 2 ? Many thanks in advance

    Piping Stress analysis & Flanged Joints

    Often, when I perform a stress analysis of pipe system ( B31.1 or B31.3 ) I have that at the flanged joints I have a lower than allowable stress. If I calculate the equivalent pressure Pe at the flanged joint location I have the ( Pd+Pe )> Prating. Due to the fact the ASME B31.1 and 3 do not...
