Bimetallic tubes for which the strength of the clad is not included and meeting the requirements of PG-9.4 shall use an outside diameter, D, in the appropriate equation in PG-27.2.1 no less than the cal­ culated outside diameter of the core material. The outside diameter of the core material shall be determined by sub­ tracting twice the minimum thickness of the cladding from the outside diameter of the bimetallic tube, including the maximum plus tolerance of the core tube. The minimum required thickness, t,shall apply only to the core material. Tubes for which the strength of the clad is included and meeting the requirements of PG-9.4 shall use an outside diameter, D, in the appropriate equation in PG-27.2.1 equal to the outside diameter of the bimetallic tube, in­ cluding the maximum plus tolerance for both the core tube diameter and clad thickness.
