Thank you very much!

Hello all, Is there a ANSI/ASME/ISO or other standard for taking 7075 T0 and tempering to T6? Our facility is trying to bring the tempering process of our aluminum in-house and we are looking for a standard to get us started. Thank you for your time

Good morning, I am working on a cost reduction project, and the idea came up of casting a fairly complex component that is currently CnC'd. Of course, the strength and fatigue characteristics of the component if it is cast will be different, but I am not sure how to calculate them. Is there a...

Thank you very much metengr! I'm still getting the hang of ASME and PV engineering so I very much appreciate the feedback.

Good afternoon all, A LH2 pressure vessel that was manufactured about 20 years ago was recently opened and had an internal inspection performed. During the inspection, it was discovered that there was incomplete penetration on the nozzle weld, and after referring to the ASME Code, the nozzle...

Thanks Mike, My confusion initially came from Appendix 1-10 which referenced large openings in cylindrical vessels. I appreciate your help on this matter.

Hello, What does ASME consider a large opening in a pressure vessel? I have a copy of ASME Section VIII Div. 1, and I have read UG-36 and UG-37; does a large opening require reinforcement and a small opening does not (therefore small openings are based upon vessel shell/head thickness)? If...

Thank you, That was my concern, the meter was calibrated to steel then used to measure thickness for copper (unfortunately, this already occurred).

Thank you very much; however, would thickness measurements be adversely affected (and to what degree) if the unit was calibrated to steel? For example, would a thickness reading on the UT meter of the copper piping at 0.120 inches be somewhat close, or just way off? The relative flaw size...

Is there a general rule of thumb for impedance ratios of different materials for UT? My question is if I have a UT meter that is calibrated to a carbon steel cal block, can I expect reasonable results if the material to be examined is copper? The impedance ratio of steel to copper is 1.4...

What failure would be expected from a 4" copper pipe (containing compressed air) that has insufficient wall thickness under 100 psig of internal pressure? I know that gases have significantly more stored energy than liquids at the same pressure, but would the pipe burst into fragments, open at...

Hello, I am sure this is a very simple question, but what does ASME mean when they reference a finished opening? I am analyzing a spherical pressure vessel which is over 3/8 in. thick and has a 10000 lb rated nozzle which is 2 inches in diameter. Section VIII Div 1 UG-36 mentions exclusions...
