Thanks DSB123 for your reply.
So when the Code says "Moments are taken at the junction point of the legs..." what I understand is that it tells you to take the resultant moments of each leg at the vicinity of their junction to make the analysis more accurate.
Is my understanding correct...
A Wye piece is considered a special type of fitting which is not addressed by the Code, but, nevertheless, is quite a delicate piece of equipment (just like a tee, but maybe more complex). I believe the Code does not address this because of its unique nature and complex non-standard design, and...
In the B31.1 Code, Para. 104.8.4(c) states the following:
"(c) For reduced outlets, calculate the resultant moment of each leg separately in accordance with (A) above. Moments are taken at the junction point of the legs, unless the designer can demonstrate the validity of a less conservative...
StevenHPerry and Zippy,
I totally agree with you. My company uses its own program that is probably not as interactive as C2 or any of the other commercial programs out there, but believe me, it is very comprehensive when it comes to the output and gives you a breakdown of all the analysis...
Sometimes if you do not understand the Code, you might be mislead or interpret the Code incorrectly.
The B31.1 Code allows you to be conservative, both with respect to the pressure stresses caused by internal/external pressure, as well as for the sustained and thermal stresses. It's only how...
Thanks for sharing that with us John.
Can you please tell me how I can get a copy?
Also, I wanted to ask you -in your opinion- if this book is better or the famous "Design of Piping System"? or maybe it is a little bit more simplified?
Of course that's a very good point; however, it is imperative that an interference check is performed during the Hot Position of the piping. We did that (that's why I didn't mention it) because that really is the main concern in these kind of issues, but I wanted to go a bit further and feel...
Can somebody share with me a useful Valves Guide (like a .pdf file or some kind of document) that speaks about the type of valves, their most common applications (which valves are used for throttling service, isolation, etc.) maybe also a little bit about their design, because I would like to...
I would really appreciate it if somebody can share something with us (like a document that speaks about Ventilator Valves and their typical installations/operation), because I think it would be very useful, especially for system and pipe designers to be aware of.
For Condensate Systems, sometimes it is preferable to have an expansion joint tied to the condensate pump's suction, not necessarily for thermal expansion (because condensate temperatures are around 38 to 40 degrees C), but because it isolates the vulnerable suction nozzle from line vibrations...
Of course it is well known that for high temperature service piping (specifically Power Piping), the piping is insulated with a considerable amount of insulation.
If there is a case were we have Main Steam/CRH piping with 165mm-191mm of insulation and, due to a layout problem (interference with...
Thanks a lot for your reply guys!
I got another question for you (which I was curious to know the answer to but never figured it out):
Why is it that some Turbine Manufacturers don't employ this Ventilator Line while others do? I understand that this is not a simple question to answer and that...
Thanks for your reply FredRosse.
Just one question: does the churning action tend to increase the energy of the steam or decrease it, because you mentioned that it increases the steam's energy in the second para., and then mentioned that the steam's energy decreases in the last paragraph...
