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.
