guys, Can somebody clarify me, how compress exempted for ASME standard flange design for both internal and external pressure. As per ASME B16.5/ B16.47 standard, pressure-temperature rating is developed for internal pressure only. So, for internal pressure design it exempted form...

Dear friends, While designing nozzle for "design for MAWP or MAP", I noticed that while checking for MAWP case for nozzles, compress is adding Liquid static head on flange. Guys, do you think it is necessary to add liquid static head? In my opinion it is not required. What do you think, guys...

if u see my attached file with additional wind load calculation u will see that Q = Weight on saddle + larger of Qt or Ql Q = W + Qt = 79,124.98 + 5,697.82 = 84,822.79 N w = Wt / Le = 157,271.34*10 / 6,648 = 236.57 N/cm where total operating weight= wt on saddles...

While going through compress calculation, I found some doubts while taking the loads during calculation. 1) Bending Moment calculation at the saddle Mq = w*(2*H*Al / 3 + Al^2 / 2 - (R^2 - H^2) / 4) Where, w=Wt/(L+4H/3) As per compresses calculation, Wt is taking as total operating weight. As...
