What Grade of A333 for low temperature use?
(OP)
I am familiar with A333 piping for low temperature service (to -50°F) and we have some in an older part of the plant for a syltherm xlt system. Unfortunately, we no longer have a specification for it on site.
What are the differences between the various Grades of A333? What criteria is used to determine if A333 Grade 1 or A333 Grade 6 is preferable? Syltherm is not corrosive to carbon steel.

Only use an Approved Piping Classification Specification
Impact Tested Carbon Steel
DESIGN CODE: ASME B31.3-2002a
RATING CLASS: ASME B16.5-2003
TEMPERATURE LIMIT: -50F to 650F
ITCS, SMLS, ASTM A333-6 (Ej=1.00)
ITCS, EFW, ASTM A671-CC60, CLASS 12, S-2 (Ej=1.00)
(Note 09):Pressure and temperature rating may be limited by certain components permitted by this specification. Refer to manufacturer’s recommended pressure-temperature restrictions.
