Hi everyone, I'am currently working on a pipeline lowering project using 4 engins (pipeline length is 1.25 Km). I assumed I can use CAESAR II to determine the adequate positions of engins which garante that neither maximum allowable stresse limits not maximum lifting capacities are exceeded...

DSB123, I've made a mistake I meant ' a piping engineer' ( I am not a native English speaker,and I know that the difference between 'piping engineer' and 'plumping Engineer' does not require high language skills) thank you for correcting me and sorry for the mistake. I might also made mistake...

Hi everyone I'm not sure if we I ask this question here , but I think it's the best way to evaluate my evolution and determine my weaknesses What are the responsibilities and skills required for a plumbing engineer with 2 to 3 years of experience? Any information or suggestions you can provide...

Hi everyone, I'am a little confused,after a discussion with mu superior at work ,I 'am working on an FRP piping system , the vendor gave us these values: - Young's modulus - axial : 13000 MPa - Young's modulus - radial : 20000 MPa - Poisson's ratio (principal): 0.4 - Poisson's ratio...

Hi everyone, Does Vh/a (secondary poisson's ratio) have to be less than Va/h (principal poisson's ration) always ? ( this is what my superior told me and didn't explain me why) , so I want to know if it's true and if yes can you please explain it to me Any help would be highly appreciated

Hi, Which criteria to check when analysing an expansion joint using caesar II, displacement, Stresses and what else ? Ad regarding displacement do i have to make sure that displacement in occasional load cases are within allowable values or i only need to cheek them in oparting and expansion...

Hi Can you help with this, I used appendix Y of ASME VIII to calculate total required cross-sectional area of bolts of a bolted flanged connections. But I don’t how can I calcule the number of bolts or determine their size. Thank you in advance

TGS4, Yes this is what i meant but how can i calculate it ??? where can i find it's formula in ASME code ??

Hi, Can any give me the formula used to determine the equivalent pressure , according to ASME, for Class 1 Flange Assembly , Category 3 flane With Spacer (metallic spacer).n other words can i replace pressure ,in equations of appendix Y and appendix 2 of ASME VIII div 1, by equivalent pressure...

Hi, In order to define Flange thkness and bolting using Appendix Y ( ASME VIII Div 1), i have ito determine Wm1 first ( Wm1 : minimum required bolt load for the operating conditions). The problem is that I 'm not sure of the approach that I made, this is what I did Wm1= H+HC+HG (Y-4 (a.4))...

Hi, I can not understand this sentence of the appendix Y-1 (a) (ASME VIII) "before the bolts are tightened or after a small amount of preload is applied to compress a gasket"

Hi Am new with the ASME VIII, and i can understand what does it mean hydrostatic end loads thank you in advance

Hi , I have two questions: First question: are Full-face gasket and flat-face gasket synonyms ??? Second question: Can i use Appnedix 2 ( ASME VIII , div 1) for bolted flange connections with full-face gasket ?? if i can't then which paragraph or appendix should i use.?? Thank you in advance

Another question , how can I calculate the thickness of the chimney from the chimney vacuum pressure ??? And there is a table of standard values ​​of thickness as a function of the pressure

Hi Is that there is a code for calculating industrial chimney ( thickness calculating for example ) used in oil refineries , If yes wherein ????
