A.3.3 Engineered solutions
When standard model codes are not sufficient to fulfill
requirements, consult the factory to explore possible
Engineered Solutions. This is typically, but not exclusively,
related to the choice of wetted materials or the design of a
process connection. These Engineered Solutions are part of
the expanded offerings and may be subject to additional
delivery lead time. For ordering, factory will supply a special
R-labeled numeric option code that should be added at the
end of the standard model string. See example model string
below.
Example Model String:
5402-A-H-1-E5-45-PV-CA-M1C1-R1234
A.3.4 Tank connection and antennas
Tank connection
The tank connection consists of a tank seal in combination
with a connection type matching the one for the tank i.e. a
flange, Tri Clamp, NPT thread or a specific welded
connection with swivel feature for parabolic antenna.
Certain models of tank connections have a tank connection
design with a protective plate of the same material as the
antenna. This is to prevent the 316L/EN1.4404 stainless
steel flange from being exposed to the tank atmosphere.
See “Dimensional drawings and mechanical properties” on
page 219.
Flange dimensions
Follows ASME B16.5, JIS B2220, and EN 1092-1 standards.
For more information, see “Standard flanges” on page 225.
