4 Transportation, Storage and
Lifting
Check and document any damages in the transport packages
or dampeners. Contact the transportation company in case of
damage. When new or unused dampeners are sitting idle for
long periods, the following procedures should be complied
with:
1. Prior to storage, thoroughly drain dampeners of any and
all water.
2. Indoor storage is required. For unfavourable
environment, cover the equipment with protective
tarpaulin that will allow proper air circulation.
3. Protect the equipment from temperature and humidity
extremes and exposure to excessive dust, moisture,
vibration, sunlight, ozone and solvents.
4. Cover the flange openings.
5. Do not store any objects on top of the rubber hoses.
6. Before operation clean the dampener.
When storing used dampeners, wash them with fresh water
and follow the steps above. For storage periods greater than
36 months, please contact Valmet Flow Control as the rubber
parts need to be changed before use.
Lifting equipment must be used for dampeners weighing
over 25kg.
Lift the dampeners securely from the cover hose (part 2). Use
soft straps for lifting as shown in Figure 4. Lifting example.
Figure 4. Lifting example.
Do not attach lifting equipment to the bore as it can damage
the dampener. For Expulse™ dampener dimensions and
weighs refer to
Appendix A
.
