Dear BigInch, LittleInch and rconner,
Great thanks to all your responds.
I would like to describe my questions more detail. In the piping material specification, the pipe wall thickness for 4" is Schedule 40S, for 10" pipe, the wall thickness is 10S, and there shown in the branch table that...
Dear professionals,
Would you please do me a favor on my question about reducing tee wall thickness?
For example, a 10"x4" reducing tee, we have pipe schedule 10S for 10" pipe and 40S for 4" pipe, so,we may need a 10S x 40S.
We know that the 4" Sch40S is thicker than 10" Sch10S, so how could...
Paddy1385,
To use the Cnode in CAESAR II is a correct solution to deal with deck deflection such as hogging and sagging.
When you have a restrain on node 100 as a +-Y maybe with guide or axial stops(assume Y is Elevation), you can have a Cnode of 101, and then fill your displacement data on...
Please refer to ASME B31.3 311.2.5

DSB123,
I recently found another dicussion with the link below:
http://www.linkedin.com/groups/Fatigue-Curve-SN-Piping-Stress-1924654.S.171183961
I found the topic was discuss much, but seldom found a clear answer, I am not quite that if I could treat it as a hign cycle fatigue case, as...
DSB123,
Thank you very much for you kind reminding.
CAESAR II will be applied to perform the calculation with code B31.3 for piping system topside. Fatigue analysis is really a big problem, however, I got to know that someone dealing with the fatigue in CAESAR II was to fill the "Fatigue...
Dear DSB123,
I apologize for breaking the rules, I post the topic here was that I found people here are more willing to talk and dicuss, I really got many good suggestions here.
It seems that the piping stress analysis on a FPSO is kind of "esoteric", while, I googled and gathered a lot...
Dear all professionals,
I have put this post in COADE forum but not got anwsers yet, so I came here for more help.
Would you please do me a favor on piping stress analysis issue for marine case?
Is there a recommended load case combination for FPSO? I understand there would be many factor...
Dear all kind-hearted friends,
Would you please do me a favor on piping stress analysis issue for marine case?
Is there a recommended load case combination for FPSO? I understand there would be many factor need to be considerred, such as wave motion, deck deflection, wind, etc. I also checked...
XL83NL, Thank you very much for you attached links, I have read the viewthreads, it seems that people prefered flange installation without washers, however, it still under discussion.
Hello all,
would you please do me a favor to answer the question?
Dose washer needed for flange connection? In my experience, we never asked for washer in piping material specifications for chemical engineering. While I looked a PMS for FLNG, I found the washer required. I did not found any...
Pennpiper,
Thank you very much for your responds, I decide to setup one guide on every second pipe restain like you said. As the project was a kind of offshore, so I think that was not too conservative.
I am tring to find a recommended table with the size, safty span and guide distance, it...
Great thanks to LittleInch,racookpe1978 and tmartin125 to my questions, I have benifited a lot from all of you.
I would like to explain more details, the critical pipes means that the pipes which will be analysis piping stress by computer software such as CAESAR II, the rest ones were of...
Dear all warm-hearted friends[bigsmile],
I am a new comer and this is the first time on posting.
Would you like to do me a favor on my questions for piping supports? For critical piping, the guide or the axial stop was set according to pipe stress analysis result, but for non-critical ones...
