IN ASME SEC II, FOR SA516 GR70
YIELD STRENGTH VALUE IS 38000 PSI
AND TENSILE STRENGTH VALUE IS 70000 PSI.
I READ THAT 38000 PSI IS A VALUE FOR 0,2% PLASTIC DEFORMATION
I TRY TO DESIGN A LIFT LUG (ONLY ONE USE AND LEAVE)
AND WANT TO HAVE 45000 PSI STRENGTH VALUE FOR CALCULATIONS.
BUT I WANT TO...
for standart flanges, in ASME B16.5
pressure and temperature ratings are given.
what is the corrosion allowance for those ratings?
especially for standart blind flanges, how can we condsider corrosion allowance?
WE HAVE A PRESSURE VESSEL. SHELL MATERIAL IS SA516GR70.
WE SHALL DO HEAT TREATMENT AT 593C(1100F) TEMPERATURE.
WE HAVE SOME SA304L ATTACHMENTS ON SHELL.
HOW DOES HEAT TREATMENT AT 593C EFFECT THOSE CRNI ATTACHMENTS?
SHOULD I WELD PADS ON SHELL AND WELD THOSE ATTACHMENTS AFTER PWHT?
ASME Sec VIII, UG53 instruct Ligament efficiency determination.
I try to design a collector pipe (D:273mm) with drilled holes
(similar to figure UG-53.1)
24 holes with (d:50mm, p:89mm)
and 2 rows of holes,
distance between two adjacent rows:65mm
As per UG-53(c), can you tell me steps to...
ASME Sec VIII, UG37(a) Defines
"h" is distance nozzle projects beyond the inner surface of the vessel wall.
when we insert plain cut-end pipe to cylindirical shell,
is "h", the length measured from center axis of pipe,
or
is "h", the minimum length measured at the...
