Impact test on Test specimens
Impact test on Test specimens
(OP)
I am qualifying a test coupon Sa333 Gr 6 to Sa 350 LF2. I have to carry out impact test at -50°F. The location of the specimen for impacts will be as follows
Set "A"
weld center Line
Haz on the pipe side
Haz on the flange side
PM on the Pipe side
PM on the Flange side
Set "B"
weld center Line
Haz on the pipe side
Haz on the flange side
PM on the Pipe side
PM on the Flange side
Set "C"
weld center Line
Haz on the pipe side
Haz on the flange side
PM on the Pipe side
PM on the Flange side
Can someone tell me whether I am doing the right thing
Regards
Merzi

Why is it required to test PM in the PQRT piece?
By the virtue of meeting the specification both A 333 and A350 LF2 are supposed to hae passed impact test at -46 Deg C.

I agree that, at least per ASME Sec VIII, UG 84, & UCS 67, no impacts are required in the base metal, regardless of it's classification.
