PFT 51 is applicable for Furnace and Tubes of Firetube Boilers. Is this item applicable for steam drums as well?

The Preamble states
"The Code does not contain rules to cover all details of
design and construction. Where complete details are not
given, it is intended that the manufacturer, subject to the
acceptance of the Authorized Inspector, shall provide
details of design and construction which will be as safe as
otherwise provided by the rules in the Code."
Your best bet is to use the rules from PFT-51.
