Sealing Flange
INTRODUCTION
Inside of a fuels subterraneous storage system (SASC), the contention
reservoirs are stanch containers used for to retain possible leakages coming
from connections or derivations. On its application, the reservoir walls must be
perforated for the tubing passage and at this moment it is necessary the use of
Sealing Flanges for to promote the stanching of these points.
7
Introduction
It is essential the use of Sealing Flanges on any perforation made on contention reservoirs for the lines passage. This procedure warrants the system
stanching.
The Zeppini FV are available on different measures and 2 different models:
–
Conventional – FV – Allows the entry of the simple wall tubing on the
contention reservoirs, as for example breather, electrical, monitoring,
fuels suction, etc. lines.
–
FV – with Secondary protection – Used on double wall lines, this
equipment has application mainly on the fuel transportation with
positive pressure, allowing the primary tube entry (tube with fuel) and
providing the external secondary tube installation, what, on case of
leakage on the primary tube, retains these leakages impeaching the
environment contamination. This FV allows also the realization of
stanching tests between the primary and secondary tubing through a
test nozzle where it is applied pressure between the tubing.
The Sealing Flanges offered by Zeppini are highly reliable and offers safety
and tranquility to the fueling stations operators. Over than, its installation it is
too simple since its fixation is made through the nut and lock-nut system what
eliminates the use of screws, nuts, etc...

TRANSPORTATION, STORAGE AND RECEPTION
The correct FV transportation and storage is extremely important for to warrant
the equipment integrity.
The FVs are packed on appropriated boxes where can be accommodated up
to 5 units per box.
For to transport and to store these products, follow rigorously the instructions:
!
Transport the FVs on adequate vehicles inside its packages.
Keep the FVs away from sharpened objects that could
damage it.
Avoid impacts during the FVs transportation.
Store carefully the FVs, protecting it against impacts,
sharpened objects and flexion.
Protect the FVs from the ultraviolet rays (UV) keeping it
stored on protected place until the moment of its
installation.
Don’t place heavy objects over the FVs.
!
If necessary to stack the FVs, do it with care. Bad stacked
equipments can slip and to cause personal injuries or
product damages.

INSTALLATION
NECESSARY TOOLS AND MATERIALS
For to install the FVs is necessary the use of the following tools and materials
according to the items below:
1.
2.
3.
4.
5.
Electrical drill
Cup-saw of appropriated size (see annex 2)
Tightening wrench on “PE”
Support wrench on “PE”
Screwdriver
We recommend the use of the Tightening and Support
Wrenches developed by Zeppini for to install the FVs.These
wrenches apply an effective and safe tightening to the
components facilitating the installation.
INSTALLATION PROCEDURE
The FV installation is divided on 3 main stages, as follows:
1 st Phase – Flange Installation
2 nd Phase – Bellows Installation
3 rd Phase – Stanching Test
!
Observe the procedures and safety warnings described on
the installation instructions.
11
Installation
1 st Phase – Flange Installation
Step 1
Perforate the contention reservoir wall on the tubing passage exact point
using a cup-saw of adequate size according to the annex 2.
Step 2
Insert the flange on the perforation made on the step 1 by the reservoir
external side.
Step 3
Insert the sealing ring on the flange thread by the RC internal side paying
attention to the ring salience that must be pointing to inside the reservoir.
Step 4
Place the Sealing Nut on the Flange thread by the reservoir internal side.
Step 5
Tighten the Flange/Tightening Nut assembly using the Support and
Tightening Wrenches with an adequate torque.
12
Sealing Flange
!
When perforating the RC wall, pay attention to the size of
the used cup-saw. It must correspond to the FV size as
shown on annex 2. Never use any other tool for to perforate
the contention reservoirs walls, as this practice can
compromise its stanching!
Install the flange, the sealing ring and the tightening nut
according to the sequence and order described on the 1 st
Stage, the non accomplishment of these procedures and
possible inversions on the components order will
compromise the equipment stanching.
The excessive tightening of the flange/tightening nut
assembly can result on components breakage, because of
this it is recommended the use of the tightening and
support wrenches developed for this purpose.
13
Installation
2 nd Phase – Bellows Installation
Step 1
Insert the side of bigger diameter of the bellows on the tightening nut
undercut.
Step 2
Install the nut clamp involving the bellows and tighten it against the nut.
Step 3
For the Secondary Protection type FV follow the step 4, for the Conventional
FV follow the step 6.
Step 4
Insert the secondary tubing by the FV until it touch on the bellows stop.
Step 5
Install the secondary tube clamp and tighten it against the tube.
Step 6
Insert the primary tubing by the FV in such a way for to trespass the
Bellows.
Step 7
Install the primary tube clamp and tighten it against the tube.
14
Sealing Flange
On the FV with secondary protection, the test nozzle must
be turned downwards for to facilitate the draining of
possible liquids between the tubing walls.
!
The Bellows installation and the clamps tightening is
indispensable in order to the FV provides stanching.
During the Step 1, assure that the bellows extremity
remains touching on the salience of the tightening nut.
15
Installation
3 rd Phase – StanchingTest
Step 1
Close the tubing entry in order to render it stanch.
Step 2
Fill the RC with water until to cover completely the FV.
Step 3
Mark the water level with the marker pencil on the Reservoir wall.
Step 4
Wait from 15 to 30 minutes and check the water level. This one must be
exactly the same previously marked.
Step 5
If there is level variation, make the necessary repairs and make again the
stanching test, otherwise the installation is finished.
16

OPERATION
The operation of this equipment is applicable only to the FV’s with Secondary
Protection and consists on to realize the stanching test between the tubing.
Step 1
Connect the “Test Kit for FV with secondary protection” on the test nozzle.
Step 2
Connect the compressed air line on the “Test Kit for FV with secondary
protection”.
Step 3
Observing the Kit manometer, inject air on the system until to reach 5 PSI on
the pressure.
Step 4
Check the manometer reading during 30 minutes, if the pressure is maintained, it means that the primary and secondary tubing doesn’t presents
damages, otherwise it must be realized the adequate maintenance on the
tubing.
Step 5
Disconnect from the FV test nozzle the “Test Kit for FV with secondary
protection”.
17
Maintenance
MAINTENANCE
The FV maintenance must be realized at each 6 months and is summarized on
the bellows cleaning and on the retightening of the equipment.
Step 1
Using a humid cloth, make a bellows cleaning for to remove possible debris
that could damage it.
Step 2
Retighten the tightening nut and all the clamps existing on the FV
warranting the stanching.
Step 3
Remove the internal valve existing on the test nozzle, make its cleaning and
install it again (*).

WARNINGS AND RECOMMENDATIONS
For to warrant the FV integrity during its entire life, follow the Warnings and
Recommendations:
!
The tubing that trespass the FVs must be perpendicular to
the reservoir walls.The tubing maximum entry angle on the
FV must be of 15 degrees, if this angle is surpassed, will
occurs serious equipment damages.
19
Warnings and Recommendations
!
Warrant that the FV don’t remains on constant contact with
fuels, as this will cause equipment damages.
Don’t allow the contact of sharpened objects with the FV
Bellows, as this could cause equipment damages and
stanching loss.
At the moment of the reservoirs maintenance, don’t step on
the FV or on the tubing that trespass it, as this practice can
cause the equipment breakage.
When handling the tubing that trespass the FV, take care for
that the FV bellows doesn’t suffers deformations, as this
could to break it.
