42 App. 1-4(f) calculation is not included on this sheet43 Nozzles may be subject to a smaller required thickness depending on location in the head.44 Only the knuckle required thickness is calculated on this sheet

45 Heads may be subject to stress relief if large elongation occurs - UCS-79(d), UNF-79(d), UG-37(a)(1)46 The UG-16(b) minimum thickness requirement has not been taken into consideration here.
