        All Nozzles other than 90° should be charged at the man hours shown for 45° nozzles.

     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.

     For General Nolex on welding, see pages 20 and 23.
