Dears, I am currently working on a project that requires the study of water hammer/surge analysis of several lines of about 4000 meters in length, a typical facility for feeding finished hydrocarbons to ships from storage tanks. Our processes department is working on the hydraulic study of the...

Hello, Please, find attached an example of a piping system. Considering water hammer effect because the valve at node 60. I want to analize in a static model the pressure effect in my piping system. I consider that the wave return to the pipe and I have to introduce a force in each change of...

Hello all, I would like to input a water hammer effect into a static model. Could anyone explain if it is correct to introduce forces according with water hammer effect into the elbows? Could anyone comment his own experience on this subjet? Thanks in advance.

Hi, Could anyone recommend some introducing guide, examples calculations, bibliography or something relating with the dynamic piping analysis? Thanks in advance.

Hello, I would like to know if anyone knows a method to estimate the piping material in project in the preliminary phase, with the P&IDs and simple Layouts. Could you recomend me some bibliography? Thanks in advance.

Hello, I am trying to calculate the pipe thinkness with the european code EN13480-3, but I don´t now where to find the mechanical properties required to determinate the tension for thickness calculation . It is concerning the values Rp0,2 , Rp1,0 , Rp0,2t , Rp1,0t , Rm and Rmt showed in the...

Hi all, I have seen a note in a pipe isometric drawing concerning a excentric reducer with the acronym (P.I.P). Does anybody know what that mean? Thanks in advance.

Hello everybody, I have a question concerning the term "N"--> total number of equivalent reference displacement stress range, that it used to calculate the factor "f" that affect the ecuation 1A Sa=f(1.25Sc+0.25Sh) showed in para 102.3.2 of ASME B31.1 I don´t know exactly how interpretate 1...
