2002-5-31 I would like some help clarifying the required thickness calculation in ASME B31.3. Someone pointed out to me that the Pipe Undertolerance (12.5%) must be added to the required thickness calculation in B31.3 . After reading B31.3 para 304.1.1 (a), I think that the code does require this undertolerance be added.

Minimum thickness of formed bends is calculated for the inside radius, the oputside radius, and the centerline radius. Bend thinning on the outside radius is estimated using the method from ASME B31.1. The estimated minimum bend thickness after thinning should be ≥ the required minimum bend thickness on the outside radius (extrados).
