    Allowable Stress in Sour Service Piping

    Hi, In sour service piping some steel grades need to be heat treated after welding and any cold work (such as bending). During stress analysis of some sour service piping we have reached a relatively high stresses in the loop bends. Although the code stress remain within the allowable range but...

    Calculating the piping fabrication works

    - I've encountered problem in my first estimation of the piping fabrication works. For estimation of quantity of welding works (and maybe threaded works) a unit named "inch-dia" is used. I couldn't find any reference for calculation of "inch-dia"s of piping (for pipes, fittings, valves, flanges...

    Operating Case Stresses

    Thanks for valuable comments. For this case there is no equipment. No disengagement from the supports happens and the guides are well located. In the Expansion load case the stresses rise up to 83% of the allowable code stress. Combined with stresses from sustained loads, the total goes high...

    Operating Case Stresses

    I'm analysing a steam line based on B31.3. After analysing the case with CAESAR II, the code stresses (Sustained, Expansion and Sustained+Occasional) were all OK, but there are some high stresses in the Hot Operating Case. Also it happens for the Hot Operating+Occasional Load. Should I ignore...
