impact test requirement in pqr

(OP)
hi

following material needs impact testing in pqr ? if yes what is examination temperature


BPV
Material : A516-70N
thk=10mm
temp : -40C




(f) Impact testing per UG-84 is not mandatory for pres-
sure vessel materials that satisfy all of the following:
(1) The material shall be limited to P‐No. 1, Gr. No. 1
or 2, and the thickness, as defined in UCS-66(a) [see also
Note (1) in Figure UCS-66.2], shall not exceed that given
in (-a) or (-b) below:
(-a) 1/2 in. (13 mm) for materials listed in Curve A
of Figure UCS-66;
(-b) 1 in. (25 mm) for materials listed in Curve B,C, or D of Figure UCS-66.

hi , again

1-if the material thickness is 0.875 inch at same temperature also impact testing required? ( As per note ucs-66 A516 G70 N falls in curve D )
2-governing thickness means plate thk with welded or non-welded attachment on plate such reinfircing pad or support thk+ throat × 0.707 ?

RE: impact test requirement in pqr

You are missing a key part of UG-20(f). It is only good to -20F.
3/8" Curve D = -55F
7/8" = Curve D = -36F
Governing thickness is given in UCS-66.

Hi

is it mentioned -20F in ug-20(f) ?

>>>> (3) Design temperature is no warmer than 650°F (345°C) nor colder than −20°F (−29°C) ?
