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.
