My company makes some large rotating assemblies as part of their line of equipment and, as a rule, uses brand-name bearing components from SKF, Timken, SealMaster, or Fafnir to name a few. Our purchsing group has come to us with a proposal to use Koyo deep groove ball bearings instead of SKF on...
I have a situation where I would like to consider using a standard F & D head in place of an ASME F & D head in a non-code vessel application. I have some internal and external loading that needs to be considered but I am struggling with how to use the formulae for a knuckle radius other than 6%...
I have a component I am supplying to a vendor to install on an ASME code vessel. It is made from AISI 8620 steel and the material certification from the mill shows the ASTM spec as #A829. The vendor wants me to furnish the ASME spec number that coincides with this ASTM spec number. Does anyone...
I've only been given the two terms: anti-static and anti-foaming. Typically, the anti-static is a nozzle hat portrudes thru the top dish and is angled toward the side wall at 45 degrees and is about 3/4" away. I'm not sure how anti-foaming would be configured.
I have been asked what the difference in construction and dimensions are between anti-static and anti-foaming nozzles. I gave a quick look to ASME PV Code, Section VIII but did not see any information. Is there a source to find this info? Did I miss it in the code? Do the dimensions differ...
If a vessel is not subject to 15PSI+ pressure during the processing of product inside but is by a platen and press exerting 60PSI+ on the product to discharge it through a discharge nozle at the bottom of the vessel, does the vessel need to have an ASME code stamp?
Regarding the same scenario...
I've got this rubbery material in a tank with air blowing over the exposed area. I am attempting to calculate how much quicker it will cool if I use cooler air instead of ambient air. It seems like a convective application to me.
I am attempting to perform some heat convection calculations on a process with a granular, rubber-type material but don't have the heat transfer coefficient for the material. I figure I could complete my calculations if I was able to find a list of heat transfer coefficients for common...
