Dear All;
I have a problem here. Currently, I have a thick wall vessel 90mm with ID of 1500mm design in Div. 2. I am using self reinforce nozzle for all the opening. The problem is the minimum design temperature is -29°C and I am trying to use SA105N for these nozzles. As per AM-218.4 Div 2, the...
Hi everyone,
For ASME Div. 1, normally we will apply 30° for bevel on forge nozzle and 45° for Div. 2.
How about PD 5500? 30° or 45°?
Thanks.

Hi,
I have a case here.
Design Code PD 5500 Cat. 1
Design Press = 271 barg
ID = 1000mm
T/T = 3600mm
Thickness = 85mm
There problem is I have a 24" manway. From my calculation, the required nozzle thickness for reinforcement is 250mm. OD of the nozzle is 1110mm and the OD of the vessel is...
Dear All,
Can anyone tell me where to find information regarding this material e.i. Yield Strength at certain temperature or the allowable stress. I mean not from the code book. Thanks a lot!!
Dear All,
I need some guide to design my vessel on blast load. My vessel is 26m ht and 3m ID with blast pressure 0.3bar @ 0.2 sec. My question is how to convert the explosion pressure 0.3bar to the force acting to the vessel.
Currently what I am doing is calculate as per wind calculation. I am...
Dear All;
Somebody told me that the compressive yield point used in external ring (for saddle) is different from the value in ASME Sec. II Part D table Y-1.
For my case
Material : SA516 GR.70N (Shell and Stiffener)
Sy in Y-1 table : 262 N/mm²
Sa in 1A table : 137.89 N/mm²
Purpose : Use for...
Hi everyone,
I have design a saddle with external ring. The vessel wall is around 22mm and the ID 4267. I am using finglow to design the saddle and the program show that it required external ring.
My problem is, the ring clash with one of the component and the component can't be move. The only...
Dear All,
I have a situation here were my design is more than 3275 psig and the client insist on Div. 1. According to U-1(d) additional stress analysis shall be carried out. Besides FEA, can anyone here advised me what type of stress analysis shall I perform? BTW, my vessel is a code stamp...
