All,
Power piping does not consider weld srength reduction factor W (Wc in Caesar II) but process pipng does and B31.3 addresses a situation where at temp. more than 1500 deg F., W should be obtain by the Designers themselves. Does anyone knows where this figure would come normally?
Thanks...
Hi Tim,
Let me say something here in my opinion. First of all supporting any pipe at elbows are often discourage by stress engineers simply becuase more often the method to locally analyze the stresses at this point is not readily available.There has been no module in Caesar II and perhaps any...

Using teflon slide plates on pipe shoe evolves normally from pipe stress analysis. A system for example, consists of piping and equipment as pumps, vessels, etc., and of course you have pipe supports. Pipe supports are of different in nature say it could slide, it could be...
So far I did have Stress Handbook by Helguero though I've not used it for a long time (a lot are not applicable anymore). And there was not a shell and tube type Heat Exchanger included but an air cooled type even then that current Caesar II module includes only the air cooled type. For a 24" to...
Hi there Harvey,
We'll sure you are absolutely right. My pressur is in gauge and I need to add 14.7 to make it absolute. I'll surely download your software and I'll visit your software homepage too. Thanks a lot for your quick help.

Phil
Hi there guys,
I know this is the right forum for this question and I believe too mostly are working on process engineering. This question could be very simple for you but it took me a while to figure it out simply becuase of the metric unit I'm not use to. I have a system running on compressed...
I thank you all guys for refreshing me on this subject. It's been a while (35 years) since I grauated my college and it's interesting to meet incidentally pressure thrust on piping system other than 90 degree. I have confirmed all your mentoring from the hydraulic books. Funny because I asked a...
I thought quickly this could be easy but it seems to give me a bit of confusion. Where you realized a pressure thrust exist, you simply multiply the inside crossectional area of the pipe with its operating pressure and, that is if the change in direction is 90 degree. How do you evaluate this...
Scalabres,
You need to join or you can be a visitor I think in the forum at COADE: http://www.coade.com/support_discussion.asp. And, simply copy and paste your problem in there.

Scalabres,
For the benifit of other who might encounter this same problem in the future, could you post this thread on COADE Caesar forum? This issue is more suited in that forum. Thanks.
Phil
Hi all,
I am evaluating an extended trunnion at the bottom of pipe. Imagine a horizontal pipe and sticking 270 degree (below the pipe) is a trunnion which is also a pipe and the length is about 2 feet from the center of the carrier pipe. To prevent the carrier pipe from moving (the pipe in...
Thanks a lot for your help Vooter. Thanks a lot Ucfse, and yes too quick to estimate something out of a pipe as a shaft, I never even thought about this as a constant just like modulus of elasticity. I have never used this figure before and never was involved in any shafting design. I just...
Hi all,
Can anybody tell me where to get the modulus of rigidity of pipe or is this figure calculable? I need the modulus of rigidity of 2" to 6" sch. 40 pipe. Thanks for help and tips.
Regards,
Phil
I heard most people saying the welded part is much stronger than the base metal attached until I finally read some actual reports claiming fatigue failure in welded parts. My queston is: Is the weld structure (meaning all portion thereof emanates from welding procedure - not the base steel...
I have not build real big models in my present evaluaton (I'm just using a 512 MB Laptop, 3.0 GHZ in my apartment) but I think there is no limit in size. The last thing I realized that did not suit one of my purpose is that it does not support evaluating torsion in shells. Seems excellent and...
