SECTION 5 – BEFORE INSTALLATION
5.1 Installation place requirements
The bladder tank shall not be installed in areas:
1. Too close to other equipments/objects that may prevent a safe access for equipment’s operation and periodic inspections.
2. Where it is subject to heat sources that may affect its safety, performance or durability.
3. Close to ammable materials or chemicals that can generate a re concern to the tank.
4. Not protected against collision or tampering.
5. Where vibrations can generate loads on the legs/saddles, tank’s nozzles and interconnecting piping (in case of vibration,
suitable damping method shall be put in place).
6. Where a potentially explosive area is present, unless supplied in the ATEX version.
7. Where wind loads exceed the calculated limits.
8. Where seismic loads exceed the calculated limits.
9. Where the corrosion due to the atmosphere is more severe than that the painting cycle is designated to withstand (e.g. where
aggressive acids like H2S are present);
10. Where the temperature is outside the range (-10 °C; +50 °C) referring to the metal shell and (+5°C-+30 °C) referring to the
water/foam concentrate;
In case of temperature below +5 °C:
a. the foam concentrate must be of a suitable freezing point rating.
b. the compensation water between the bladder and the tank shell must be mixed with acceptable anti-freeze compounds at a
suitable mixing ratio whilst ensuring the tank contains the anti-freeze solution permanently. Please contact Viking for details on
the anti-freeze compounds compatible with the bladder material and to be instructed on the appropriate mixing ratio.
Most of the anti-freeze solution are ammable and can cause irritation by contact on eye and skin. Please always refer to the
relevent MSDS
