LONG TERM STORAGE
7.1
The valves have been shipped in the closed position. Upon receipt of the valves
at destination, the crates should be examined thoroughly for signs of mishandling
or damage during shipment. With the valves strapped to the shipping skids, all
bolting should be checked to ensure that the joints are secure. Bolting on
occasion, may become loosened during shipment and handling.
7.2
The valves should then be stored in a sheltered area to protect then from the
elements, dirt and foreign material. They should not be exposed to the
atmosphere, uncrated or removed from the shipping skids except in a clean area
just prior to installation.
7.3
If the valves are not to be installed within a short period of time after receipt, and
will require long-term storage, the following should be adhered to:
(a)
They should be stored in an upright position, shaft vertical and where
there is minimal temperature variations and the temperature does not
drop below 50°F.
(b)
In their storage condition, the valves should be wrapped in polyethylene to
prevent accumulation of dust or foreign matter.
(c)
A check-off tag should be affixed to each unit and should be dated and
signed off by the inspector witnessing the inspection which is
recommended at six (6) month intervals.
The shelf lift for grafoil and graphite filament packing is indefinite when
stored under the proper conditions.
