For any temperature below -29°C (-20"F), the

   rating shall be no greater than the rating shown for    -29°C (-20°F)

   The -29 deg C is the PT rating and not a limitation on the use of the material. Temperature limitations is covered by the material specification or the applicable design code.

For liquid Ethylene (Cryogenic media) with -164º F Design temp and SS304L material, which standard is applicable for flanges and bolts ? (because in B16.5 in Temp-Rating tables the Min Temp. is -20 F which is not in our range)
