Hi,I'm mecánical engineer at años oil refinery and oír desining specifications shows a 177 grades Celsius as designing temperatura,at least
Why this value?
Thanks
Hi,
I am mecanical engineer and currently piping designer at an oil refinery.I would like to knw if there is a calculating method for determining vaccum presure and metal designing temperature when a large and big pipe is conected with a tower while it's being vaporizating prior to a unit...
hi,
I would like to hnow about experiences in high temperture service.I think that there are restrictions, but dont know how to evaluate metal temperature and how to evaluate which is the strength wall thikness.
my case is a 4 " carbon steel steam service, 430 degrees and 40 bar, trying to...
I would like to calculate heat losses in an insultaed pipe, 100 mm of mineral wool insultaion, 300 meters length, 6", wtih inicial temperature of 362ºc
After that, how could I know final temeprature?
thanks
if the boiler has no continous oeration be careful, under insulation, because o corides streess corrosion cacking
carbon steel is cheaper for thet service, Icant understand why using stainless steel
Hi again,
Safety service is a topping tower, atmosferic destilaton tower, with 40.000 NM3 gas release.
equation 22?? could you please tell me which page of new code, I can't see it.
It's a vey nice notice that dilucion with air, and not to be a problem
Regards
Thank yoy very much for your answer, and the tecnical chapter attached.
IT is a very dificult method, and it must be analized for a spezialized engineering company.
I was looking for a more practical method, like standarized tables.Somebody told me about NFPA publicated practical tables...
Hi,
I would like to know if it's any code which covers how to evaluate the necesary flow of steam to have a proper dispersion at an atmospheric discharge of a safety valve in LPG systems.
Thanks
