3.2 Storage rules
To preclude damages during loading and
unloading, move the valve with suitable lifting
gears. Handwheels and other driving elements
are unsuitable as impact points. The transport
shall preferable take place by cable or
transport pallet.
At delivery provide the outsides of all ferritic
parts of the safety valve except the welding
edges with a coat of paint.
The insides of the body are protected by a
watery corrosion preservative that has a
long-term effect because of the film formative
activeagents.
All connection inlets are closed by
corresponding caps.
In this state the safety valve can be stored in
closed, dust-free and dry rooms lying on a
pallet without difficulties. Time of storage about
six months. Storage of more than six months
asks for disassembly and visual check of the
inner parts of the safety valve. A weather-
protected outside storage is not allowed.
For spare parts out of elastic material
(O-rings, scraper rings, rod and piston gaskets)
additionally apply:
Temperature: the temperature of the storage
shall be between 0°C and 25°C since otherwise
a hardening of the material and so a shortening
of durability will follow. Shield heating elements
and lines in heated storeroom so that no direct
heat irradiation arises. The distance between
the heat source and the stocks has to be 1 m
at least.
Moisture: to prevent the formation of
condensate, avoid moist storerooms. A relative
humidity of below 65% is at best.
Lighting: the products of elastic materials
are to protect from direct sun light and from
strong artificial light with a high ultraviolet
part. Therefore supply the windows of the
storerooms with a red or orange (in no case
blue) paint.
Ozone: protect products of elastic materials
from ozone (formation of cracks and
embrittlement). The storeroom may not
contain ozone generating systems (fluorescing
sources of light, mercury vapour lamps,
electricmotors,etc.).
Oxygen: protect products out of elastic
materials from draught by storage in
airtight tanks. Oxygen causes cracking and
embrittlement.
If these requirements are guaranteed for
products out of elastic materials, the storage
time is about 5 years.
For spare parts out of steel
Store the parts in closed, dust-free and dry
rooms so that damages do not occur.
Especially the following protection
measuresapply:
Disc (4): wax coat of the gasket, net coat
Guide bush (6): protection by net coat
