Hello All,
I have two doubts regarding cyclic service / fatigue analysis thay I can't understand, and I'd be very pleased if you could give me a hand:
1- The vessel (horizontal drum, thickness 1/2")has temperature cyclic service. The vessel is at ambient temperature (20ºC = 68ºF), and when the...
Hello All,
I am currently designing a small vessel, which needs to be supported on lugs, and I have a doubt.
The vessel dimensions are Tl-TL 2000mm aprox 79") and diameter 600mm (24"). MAterial SA-240 304, the same as lugs.
Due to piping needs if we install it on four lugs it's really difficult...
Hello All,
Could someone confirm me if there is a maximum length for long weld necks?
The client is asking for a vessel in cyclic service to provide self-reinforced nozzles for those bigger than 2" and LWN nozzles for 2" and less. (Something quite usual).
The problem is this vessel will have...
Hello all,
I am currently designing a vessel which is provided with a 24" blind flange as top head.
In this blind flange we have three connections (liquid outlet of 3", LT of 2" and PT of 2").
Is it possible to model/calculate this in comprees?
At the moment I couldn't manage to do it. Does...
Hello All,
In my project we're now designing one vessel which, according to procces data sheet, is expected to have cyclic service conditions in its operation.
The vessel is designed by ASME VIII Div.1, but the client specification asks to study cyclic services by Div.2, which is normal...
Hi All,
Currently I'm designing a pressure vessel in which design temperature is -65ºC / + 65ºC (-85ºF / +149ºC).
The vessel dimensions are ID 1300mm (4.26ft) x TT 2500mm (8.20ft), and the supports height from tangent line will be 1500mm (4.92 ft).
The operation temperature of the vessel will...
