What is the criteria for selecting heads of heat exchanger? I read somewhere that design pressures are used as a criteria for the selection. For eg, torispherical heads are for design pressure less than 15 bar. Similarly, ellipsoidal heads are for pressures greater than 15 bar. Is there any...
What is the definition of girth flange in the context of shell and tube heat exchanger? I tried finding a concrete definition in books/ASME BPVC Sec VIII Div 1/ TEMA standard but I'm unable to find. Any help is appreciated. Further, can a girth flange be bolted to channel cover?
Is there any chart or table or references guide that lists material and grade selection for heat exchangers (shells, channel, tubes etc), tanks, piping, flanges etc based on temperature, pressure, fluid, corrosivity, weldability etc? Any help would be appreciated.
New to Pressure Vessel Design. I have a question regarding TEMA Type D (Special High Pressure Closure) design. I'm unable to understand components of Type D. Does it consist of shear ring/channel cover/partition plate/nozzle/stub end/diaphragm gasket/gasket of any type? Can you label it on image...
We are procuring an ASME Section VIII Div 1 designed heat exchanger from a vendor. Vendor has enlisted a few items in notes whose reference I'm unable to find. Does anyone know references of these?
Butt weld preparation tolerances: Bevel angle: ± 5 degree
Root gap: ± 1.5 mm
Face root: ± 1.5 mm...
