Hi everyone
I'm sorry if my question is very basic, but I've been reading on the Unified Screw Threads and seem to misunderstand the nomenclature.
How were the UNC and UNF standard defined? Why is for example 2 1/2 - 4 UNC but 2 5/8 is 4-UN and then the 2 3/4" is 4UNC?
Is there a common...
Hi guys,
We have a project in which the refurbishment of a servomotor was given to an external company.
This equipment will only be installed for another 10 years, before a larger project will replace all the equipment in the substation.
Therefore, the company was told that no changes to the...
Hi!
In UG-79, is the minimum thickness after forming supposed to be larger than the minimum thickness calculated?
Can the minimum thickness after forming be smaller than the one calculated?
I did not find this clear when reading the article..
Thanks!
Hi yall!
I have been having quite a hard time with a question that seems so simple; what is the minimum wall thickness allowed when performing ultrasonic examination?
I thought that it would be the minimum wall thickness calculated as per the Code, however, I have found UG-16(c) and UG-79 that...
Hi guys,
I am a young engineer with no particular experience in compressed air systems. We have about 300 5-stage air compressors compressing air at 3600 psig with a flow rate of about 29 cfm.
My employer has asked me to develop end of life criteria for these compressors. These end of life...
Hi,
We own about 900 pressure vessels dating to about 1980. How do I calculate the minimum thickness required for these pressure vessels? I am under the impression that I need to use the ASME B&PV but I am curious as to what edition I need to use. It seems to me using the last edition (2010) is...
Hi Guys,
I have read quite a few threads about thread engagement calc's on the site, but I would like to know if any of you know if ASME or any other standards recommend a certain thread engagement (ex. 1xd) for certain general situations.

Hi,
I need to determine the life expectancy of high pressure piping (stainless Steel), between 600 to 3600 lbs in a compressed air system maintained at -80C dew point. The system is located inside, so it is not subjected to rain, snow, or UV. The air flowing inside the pipes is very dry.
We...
