Charpy testing
(OP)
Hi,
Can someone help me with searching API requirements for Charpy testing? I need to know requirements of impact energy for temperatures from 20 til -60 for laser/arc hybrid welded X70.
Thanks in advance.

I'm not sure whether the latest release of the API 5L does not give acceptance criteria for impact testing. For grade X70 you should also know the PSL as per API 5L.
Good luck.

To arrest crack like flaws at high applied stress levels, absorbed energy of 30 to 35 ft-lbs (Charpy V-notch)were often specified at the minimum design temperature if the design stress was 70% of the SMYS for X70 pipe.
