Informazioni di sicurezza supplementari - Additional Informations for safety
Lavorare in sicurezza con prodotti
in ghisa per linee vapore
I prodotti di ghisa sono comunemente presenti
in molti sistemi a vapore.
Se installati correttamente, in accordo alle
migliori pratiche ingegneristiche, sono dispositivi
totalmente sicuri.
Tuttavia la ghisa, a causa delle sue proprietà
meccaniche, è meno malleabile di altri materiali
come la ghisa sferoidale o l’acciaio al carbonio.
Di seguito sono indicate le migliori pratiche
ingegneristiche necessarie per evitare i colpi
d'ariete e garantire condizioni di lavoro sicure
sui sistemi a vapore.
Movimentazione in sicurezza
La ghisa è un materiale fragile: in caso di
caduta accidentale il prodotto in ghisa non è
più utilizzabile. Per informazioni più dettagliate
consultare il manuale d'istruzioni del prodotto.
Rimuovere la targhetta prima di effettuare la
messa in servizio.
Working safely with cast iron
products on steam
Cast iron products are commonly found on steam
and condensate systems.
If installed correctly using good steam
engineering practices, it is perfectly safe.
However, because of its mechanical properties,
it is less forgiving compared to other materials
such as SG iron or carbon steel.
The following are the good engineering practices required to prevent waterhammer and
ensure safe working conditions on a steam
system.
Safe Handling
Cast Iron is a brittle material. If the product is dropped
during installation and there is any risk of damage
the product should not be used unless it is fully
inspected and pressure tested by the manufacturer.
Please remove label before commissioning

Evitare il disallineamento delle tubazioni - Pipe misalignment:
Installazione dei prodotti o loro rimontaggio post-manutenzione:
Installing products or re-assembling after maintenance:
Evitare l’eccessivo serraggio.
Utilizzare le coppie di serraggio
raccomandate.
Do not over tighten.
Use correct torque gures.
Per garantire l’uniformità del carico e dell'allineamento,
i bulloni delle ange devono essere serrati in modo
graduale e in sequenza, come indicato in gura.
Flange bolts should be gradually tightened across
diameters to ensure even load and alignment.
Dilatazioni termiche - Thermal expansion:
Gli esempi mostrano l’uso corretto dei compensatori di dilatzione. Si consiglia di richiedere una
consulenza specialistica ai tecnici dell’azienda che produce i compensatori di dilatazione.
Examples showing the use of expansion bellows. It is highly recommended that expert advise is
sought from the bellows manufacturer.

construction, as well as the proper use of tools and safety equipment must also be complied with.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information
Sheet, check that the product is suitable for the intended use/application. The products listed below
comply with the requirements of the European Pressure Equipment Directive 97/23/EC and carry
the mark when so required. The products fall within the following Pressure Equipment Directive
categories:
Product
DN15 - 32-1-SEP
5800
9800
5800/Z
9800/Z
i) The products have been specically designed for use on propane or methane gases which are
in Group 1 of the above mentioned Pressure Equipment Directive. They can also be used on
steam, air or condesate wich are in Group 2 of the Pressure Equipment Directive. The products'
use on other uids may be possible but, if this is contemplated, Spirax Sarco should be contacted
to conrm the suitability of the product for the application being considered.
ii) Check material suitability, pressure and temperature and their maximum and minimum values.
If the maximum operating limits of the product are lower than those of the system in which
it is being tted, or if malfunction of the product could result in a dangerous overpressure or
overtemperature occurrence, ensure a safety device is included in the system to prevent such
over-limit situations.
iii) Determine the correct installation situation and direction of uid ow.
iv) Spirax Sarco products are not intended to withstand external stresses that may be induced
by any system to which they are tted. It is the responsibility of the installer to consider these
stresses and take adequate precautions to minimise them.
v) Remove protection covers from all connections before installation.

1.6 The system
Consider the effect on the complete system of the work proposed. Will any proposed action (e.g. closing
isolation valves, electrical isolation) put any other part of the system or any personnel at risk? Dangers
might include isolation of vents or protective devices or the rendering ineffective of controls or alarms.
Ensure isolation valves are turned on and off in a gradual way to avoid system shocks.
1.7 Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure. Consider double
isolation (double block and bleed) and the locking or labelling of closed valves. Do not assume that
the system has depressurised even when the pressure gauge indicates zero.
1.8 Temperature
Allow time for temperature to normalise after isolation to avoid danger of burns.

3. Installation
Note: Before actioning any installation observe the ‘Safety Information’ in Section 1.
Referring to the Installation and Maintenance Instructions, body name-plate and Technical Information
Sheet, check that the product is suitable for the intended installation.
3.1 Check materials, pressure and temperature and their maximum values. If the maximum
operating limit of the product is lower than that of the system in which it is being tted, ensure
a safety device is included in the system to prevent overpressurisation.
3.2 Determine the correct installation situation and the direction of uid ow.
3.3 Remove protective covers from all connections, before installation.
3.4 The separators may be lagged if required.
3.5 Important installation note
Install in a horizontal pipeline with the drain directly below.
Provide suitable support to the system to minimise piping loads.
To ensure that any separated liquid is drained quickly, a suitable liquid drainer or steam trap must
be connected to the drain connection.
For those steam systems where air can be present, air can collect in the upper portion of the separator.
In this situation a suitable air vent should be connected to the air vent connection.
If an air vent is not being tted then the connection must have the plastic transit protection plug
removed and must have a carbon steel class 3000 lb plug tted.
