Dear experts
i want to check the local stress during lifting in a tower around of a trunnion.
i have checked its trunnion in code calc. and check wrc107 in its related page but after calculation in its report maximum allowable stress for wrc in this case(trunnion lifting) are "1.5*Sa" and check...
thank you Afox88
but I'm using HTRI V6 sp2
and i have the properties in tow temperature that are pointed . are they enough?
our fluid isn't in critical condition
I SHOULD ADD : THE 3G REFRIGERANT IN THE INLET IS A MIXED FLUID. AND HTRI WANT FROM US TOW CONSTANT (LATENT HEAT AND CRITICAL PRESSURE) THAT WE DON'T HAVE THEM .
I'M SO CONFUSED AND NEED YOUR HELP IMMEDIATELY .
HI DEAR ENGINEERS
WE HAVE A PROCESS DATASHEET FOR DESIGN A SHELL AND TUBE HEAT EXCHANGER TYPE "BKU". IN THE DATASHEET WE HAVE SOME PROPERTIES OF DESIRED FLUIDS. ONE OF THE FLUIDS IS ETHANE (THAT WE DON'T HAVE ANY PROBLEM WITH IT ) AND THE OTHER ONE IS "3G REFRIGERANT" . WE ONLY HAVE THESE...
very thank you
but in the shell and tube heat exchanger that we require pwht and tube to tube sheet joint is "seal or strength" weld , i don't know what am i doing. please guide me for this problem.
best regards
thank you.
the material of plate is carbon steel sa 516 70 (thk 34 )
the material of tubes are sa-179
and per API 661 we shall be doing PWHT on headers .
in the air cooler heat exchanger we have to doing PWHT on header but i have to weld tube to tube sheet (strength or seal weld)and as you know we shan't done any welding after pwht. Please guide me ho to solve this problem.
