The calculation of pressure vessel wall thickness is made with formulae usually imposed by national codes. Although the Lam茅s formulae give actual stresses and leave the decision on the safety factor to the designer, these codes impose certain safety factors in the calculation of allowable ...
For tmin calculation, it is always liquid (process) SG considered for Design Pressure calculation with static head. I am not sure why the AI should consider water SG for tmin. This could trigger a vessel rejected when it is still acceptable by design. In your case with heavier SG, you ...

whereDis the internal diameter of the shell (mm),eis the thickness of the metal (mm),Pis the calculation pressure (bar), σ is thepermissible stress(N/mm2) and λ is a coefficient, not exceeding unity, which allows for any weakening due to welds. ...
Background Theory of Pipe Wall Thickness Calculation The calculation of pipe wall thickness is a critical aspect of piping design, ensuring that pipes can safely withstand the internal pressure and other loads they may encounter during operation. A pipe is considered to be a thin-walled vessel and...
Recommended for you TomBarsh(Structural)17 Jul 06 14:49 Kelly, The required flange thickness may be based on either the calculated stresses or the flange rigidity. In re-rating calculation mode ("Get Pressure Rating") the flange stresses are calculated and reported based on the actual flange ...

The calculation models are denoted as “pqSrBsNt,” where - “p” stands for type of stiffener p = F: flat-bar; p = A: angle-bar; p = T: tee-bar - “q” stands for aspect ratio of local plate q = 3: a/b = 3.0 q = 5: a/b = 5.0 - “r” stands for size of ...
The latter occurs under the influence of negative pressure gradient. A commonly-used criterion of separated flow is m≤–0.082. The calculation sequence is iterated to convergence. The formulation will allow incorporation of some embellishments. In the meantime, Fig. 14.4 anticipates the independent...
