Severe service conditions 31
2.4 Severe service conditions
If product owners or personnel expect that the Senior will encounter severe conditions
(environment where there is likely to be an accumulation of sediment for any cause), then
Daniel recommends the removal of the Drain Valve Plug (30) near the bottom of the Senior and
the installation of a blow down valve in its place (refer to Section 3: Maintenance ).
2.5 Corrosive service
Corrosive environments may affect both the external and internal surfaces of the Senior. Daniel
defines external corrosive environments as those conditions that affect the outer surfaces of the
Senior, while an internal corrosive environment is a condition that affects the surface inside the
Senior. Read, understand, and follow instructions in the sections below if an internal or external
corrosive environment exists.
2.5.1 External corrosive environments
For Seniors located in external corrosive environments (offshore platforms, marine terminals,
etc), Daniel recommends replacing the standard carbon steel Equalizer Valve (Complete) (1),
Bleeder Valve (Complete) (10B), Grease Gun (Complete) (23) and Drain Valve Plug (30) with the
stainless steel versions listed in the “Corrosive Service” column (refer to Tab le 2-1 ).
