1. The valve, either crated or uncrated, should always be
kept with the inlet flange down, i.e., never laid on its
side, to prevent possible misalignment and damage to
internals.
2. Pressure relief valves should be stored in a dry
environment to protect them from the weather. They
should not be removed from the skids or crates until
immediately prior to installation.
3. Flange protectors and sealing plugs should not be
removed until the valve is ready to be bolted on to the
installation.
4. Pressure relief valves, either crated or uncrated, should
never be subjected to sharp impact. This would be most
likely to occur by bumping or dropping during loading
or unloading from a truck or while moving with a power
conveyor, such as a fork lift truck. While hoisting to
the installation, care should be exercised to prevent
bumping the valve against steel structures and other
objects.
5. Uncrated valves should be moved or hoisted by the
three eye bolts located on the top flange of the valve
(See Figure 1, Item 26). Crated valves should always be
lifted with the inlet flange down.
6. When pressure relief valves are uncrated and the flange
protectors removed immediately prior to installation,
meticulous care should be exercised to prevent dirt
and other foreign materials from entering the inlet and
outlet ports while bolting in place.
7. "Short Term Storage" is defined as storage not exceeding
six months from date of shipment. "Long Term Storage"
is defined as storage not exceeding one year from date
of shipment. "Extended Storage" is defined as storage
exceeding one year from date of shipment.
8. For Extended Storage, items shall be stored within a
fire resistant, tear resistant, envelope and stored in a
weathertight, and well ventilated building or equivalent
enclosure. Precautions shall be taken against vandalism.
This area shall be situated and constructed so that it
will not be subject to flooding; the floor shall be paved
or equal, and well drained. Items shall be placed on
pallets or shoring to permit air circulation. The area
shall be provided with uniform heating and temperature
control or its equivalent to prevent condensation and
corrosion. Minimum temperature shall be 40°F (4.4°C)
and maximum temperature shall not exceed 140°F
(60°C). Valves or parts shall be stored in the original
shipping container. The shipping container shall be kept
in an upright position as indicated by the markings on
the crate. DO NOT STACK. Level B storage requirements
as specified in ANSI N45.2.2 shall apply. All material,
upon receipt, should be inspected and all coatings and
packaging damaged during shipping and handling shall
be put into like new condition before storing.
9. For Long Term Storage, items shall be stored indoors or
equivalent with all provisions and requirements as set
forth in extended storage items except that heat and
temperature control is not required. Level C storage
requirements as specified in ANSI N45.2.2 shall apply.
10. For Short Term Storage, the storage requirements are
the same as those specified for Long Term Storage.
11. For any reason should it be necessary to store the valve
in an uncrated condition, the valve shall be stored in
an upright position on the inlet flange, making certain
the inlet flange is protected from damage. Never lay
the valve on its side as damage to the internals and
misalignment may be incurred. The valve, when removed
from the shipping container, shall have the protectors
left intact to prevent entrance of foreign materials. Use
all precaution to prevent the entrance of dirt and foreign
material into the valve.
