     Pipe Thickness: Wall thickness of the pipe used for the nozzle determines the man hours that
         will apply. For nozzles of double extra strong pipe thickness, use Schedule 160 man hours.
     Reinforcement: Man hours are for labor only. The price of the nozzle and reinforcing materials
         must be added.
     Preheating; If specified or required by Codes, add for this operation. See man hours for pre­
         heating. The size and wall thickness of header (not the size of the nozzle) determines the
         preheating man hours.
     Stress Relieving: Stress relieving of welds in carbon steel material is required by the A.S. A.
         Code for Pressure Piping, where the wall thickness is 3/4" or greater. The size and wall
         thickness of the header determines the man hours to be used for stress relieving.
         All pipe sizes shown below the ruled line are 3/4" or greater in wall thickness and must
         be stress relieved. Where stress relieving is required an extra charge should be made.
         See man hours for stress relieving.
