Re: Help(Document link: Prasad

Dear Makarand
Coming to your query, as per ASME B31.3 ASTM A 333/6 can be used below
-45.5-deg. C (-50-deg. F as allowed by code without any special
precautions) with following precautions:
1) Testing of Base metal at minimum design temperature (-60 deg C in your
case.) as per B-3 of table 323.2.2 of B31.3. This is useful for the
procurement part.
2) For fabrication and welding part, special precaution has to be specified
for impact testing of Weld metal and HAZ. This is useful for specifying in
the welding specification or construction specification. You will have to
specially mention this in the p.class so that it will be highlighted to
QA/QC or welding engineer.
I hope this clarifies. Let me know if you need any further information.
With best regards,
Prasad Joshi
