Thank you for your responses.

haha luckly this particular piping system is for an experiment and is not nuclear

I am protecting components and associated piping. I read the suggested topic but could not draw a conclusion from it.

I would like to know if the requirements ASME Sec VIII, Div 1, Subsection UG-140 (Overpressure Protection By System Design) would apply to B31.1 and B31.3 designed system that do not have safety valves installed for overpressure protection? I have read both codes and neither one mentions the...

Is a rupture disk considered a pressure reatining item, given that its purpose is to burst at a certain pressure? Thank you, Alex

Hello, could someone please let me know which section of ASME Sec VIII, Div. 1 discusses openings in pipes (eg NPS 3/8 pipe connected to in NPS 1 pipe). Thank you, Alex

Is there a section which covers this type of design or would I have to do as stress analysis showing that the stresses are withing the code allowable stresses? Thank you.

Jt, I forgot to mention that the customer wants to have a fitting screwed onto the flange, with a weight attached to it. Is that allowed by the ASME codes?

I completed the design of the blind flange. Thank you all for your help. I am also required to design an additional blind flange, which has a partial penetration located in the center of the flange, as shown in Sketch 1. I have read the code and I was unable to find anything that would help me...

Which dimensions do the dead diameter and the shortest span refer to when it comes to a blind flange?

I am required to make 4 x 1/8" NPT holes in a class 150 blind flange and would like to know if the rules of UG-36 (Openings in Pressure Vessels) apply to the design. Thank you.

Thanks to all for the great advice. Alex

Thank you for the great advice. Alex

The valves are installed upstream of the safety valve, as shown in the sketch. http://files.engineering.com/getfile.aspx?folder=2f66fc7a-e61e-478d-87c2-ff46c835bdde&file=Sketch_1[2].bmp

I would like to know if the the pressure safety valve installed on the vessel (shown in the attached sketch) is required by the code to relieve the steam capacity in the event of steam ovepressurization, even though the steam input has its own safety device set at the same pressure of the...
