Hi,
I am currently reviewing the design of a tube sheet for a boiler that is made from stainless steel and has stainless steel piping welded to it. This falls in line with subsection HG-346 of Section IV of Asme which allows me to calculate the required thickness of the plate, which I have...
Hi,
This is a very entry level question but when doing the pressure calculation for a pressure vessel based on ASME, should I be using working pressure or Hydrotest pressure for my calcs? Not sure if the calculations factor in the allowance for the hydro or if that should be my value for the...
Hello,
I am currently investigating the redesign of a heat exchange unit that uses SS helical coil for heat transfer purposes. One avenue of investigation I am reviewing is to use fin coils instead of the standard 1.25" tubing to reduce the overall length of the required coil whilst giving...
Hi,
I am currently designing a pressure vessel system for hot water with a max temp of 99C and operating pressure of 160psi. The part is shaped like a donut with wholes through one face to allow for hot water piping to be welded as this unit will be part of an outlet manifold. I am double...
Hi All,
Want to bring this back to basics for a minute. I work for a gas company and someone came in with a simple question.
A sealed pipe of natural gas rises 100m. the pressure at the bottom is 3kPa. What is the pressure at the top?
I believe the pressure is less due to Bernoulli's...
