4. Place the Emerson-supplied O-ring onto the groove.
WARNING
Failure to properly install the gasket may cause process leaks, which can result in
death or serious injury.
5. Insert the SSW hygienic tank spud seal into the tank spud.
6. Attach the Emerson-supplied clamp and hand-tighten the connection.
3.16.3
Tank preparation
When preparing the tank, ensure an area with a minimum diameter of 9
¼
-in. (235 mm) is
available to properly weld the tank spud. The center of the tank spud should be at least
1
½
-in. (38 mm) below the minimum measurement level. To get a proper process fluid
measurement, half of the remote seal diaphragm must be covered.

A. Tank spud
B. Hole cut
C. Center of the hole
D. Weld
Attempt to cut the hole as smoothly and as circular as possible. A torch cut is not
recommended. The tank spud O.D. is 5.98-in. ± 0.010-in. (152 mm ± 0.25 mm). When
cutting the hole for the tank spud, the gap between the hole diameter and spud O.D.
should be held to a minimum. It is recommended that the hole be no larger than 6.020-in.
(153 mm). Anything larger than 6.020-in. (153 mm) could increase the amount of tank
spud distortion.
If a bevel(s) is required, an angle no larger than 37.5° is recommended; see ASME B16.25
for more details. Bevels can be made on one or both sides of the tank. Do not grind or cut
the bevel to a sharp point. Attempt to leave a flat area.
