80-10® HEADS

OD - Outside Diameter
THK - Thickness
OH - Overall Height
SF - Straight Flange
RD - Radius of Dish
ICR - Inside Corner Radius
IDD - Inside Depth of Dish
Meeting all A.S.M.E. Unfired Pressure Vessel
Code requirements, the 80-10' Head permits
significantly higher pressures than other
configurations selected for the same service.
Figure 1. The 80-10·•· Head is named for its unique
INTERNAL PRESSURE COMPARISON dimensions-the dish radius equals 80% of the
head diameter and the inside corner radius
equals 10% of the head diameter. These
304 S.S., 100 P.S.I., 100°F dimensions compare to 100% and 6%
I respectively for A.S.M.E. F&D Heads.
