A
Dimensions are for heater faces at the commonly used operating temperature of 500°F (260°C) (see Annex A1 for dimensions for coated, aluminum heater faces at
73.4°F (23°C )).
B
Recommended heater faces should be manufactured close to maximum diameter for fitting heater faces and close to minimum diameter for pipe heater faces to allow
for wear and recoating.
C
Minimum dimensions have zero negative tolerance. Maximum dimensions have zero positive tolerance. The sketches and designs of the heater faces are illustrative
only. Entrance and base chamfer or radius is optional. The maximum entrance and base chamfer or radius is 0.03 in. (0.7 mm).
D
“F” Depth Tolerances are intended as a point of measurement of “E” diameter only and not as a limit of actual socket tool depth. The depth of the pipe heater face
socket may be of any dimension greater than “F”.
