These procedures outline the general requirements for
storage of MOGAS valves.
TRANSPORT
For export shipping, valves will be shipped in sea-
worthy, export-packed, plastic-lined wooden crates.
Upon arrival at the site, inspect the general condition
of the valve (and actuator, if supplied) for any potential
shipping damage.
PRE-INSTALLATION STORAGE
Valves shall remain stored in their shipping crates, or
on their pallets, with the lids secured.
Valves are shipped with corrosion-resistant paint
and desiccant dries (dryer bags) for storage up to six
months.
For long-term storage, the machined internal parts of
carbon and low alloy steel valves should be sprayed
with a rust preventative.
Keep all protective covers and plastic liners in place.
REMOVING VALVE FROM SERVICE
Before the valve is removed from the line, it should be
placed in the partially
open
position to relieve trapped
pressure and prevent further internal damage to valve
components.
Do not place the valve in the fully open position until it
has been cleaned of service debris in the next step.
The valve should be placed in a vertical position, or
raised at an angle. The bore of the valve should be
either steamed cleaned or power washed to remove
slurry and debris.
Rotate the valve to the fully open position to drain
and dry. A petroleum-based rust inhibitor should be
applied through the bore of the valve immediately
after the valve is dry.
Flange protectors need to be secured to each end of
the valve to prevent any foreign debris from entering
the valve. It is recommended to place desiccant dryer
bags inside the valve before storage.
The valve should be stored in the vertical position, out
of the weather (inside), until repairs can be made.
