      Construction:  End  closures  as such are  field  fabricated closures; orange  peel,  saddle, or flat plate type.

      Preheating: If specified or required by  codes, acid  for this  operation. See  man hours for  preheating.
      Stress Relieving: Stress relieving of welds in carbon steel material is required by the A.S.A. Code of Pressure Piping
       where the  wall thickness is  ;V4" or greater.
       Above wall thickness  .750 through  6.00 must  be stress relieved,  if the  end closure involves a circumferential weld.
       See respective  table for stress relieving.
