Charpy Test
Charpy Test
(OP)
I designed a shell of 127 ID and 60 in length in advance pressure vessel software. the software says that the result is questionable and says charpy test is required?. Can any one explain why charpy test is required? I am doing Full RT, 100% weld efficiency.
thanks
thanks

These may fall in the impact requirement range.

RE: Charpy Test
Search your ASME Codes for UCS-79 and Part D regarding
allowable extreme fiber elongation. This usually triggers
the APV software to include a warning in the shell or
head design report.

There is an excellent article regarding the impact testing requirements of Part UCS at the following link:

The article is called "The Impact Testing Enigma"
Good reading.
