Wolf Tank provides technical resins and lining solutions for storage tanks. Their DOPA system transforms single-walled tanks into double-walled tanks through the application of epoxy resin layers and other materials to create an interstitial space. This system has approvals from testing organizations and provides leak detection and environmental protection. Wolf Tank also offers coatings and sealants for tank roofs, shells, bottoms, ring walls, and containment areas to protect against corrosion and extend tank lifetimes.

TELECONTROLLO is an online platform to monitor
remotely leak detection systems DOPA®
Main reasons to remotely monitor alarms:
 User account with overview of all stations
 automatic maintenance alert
 long term information for warrenty issues
 possibility to preview underpressure losses
already in early stages
Directly on the Webaccess for every station/tank the
daily pressure values are available and plotted on a
diagram.
Remote monitoring delivers an additional

DOPA® Double Wall Tank Lining
for Underground Storage Tanks

16. www.wolftank.com
DOPA6N is a system to transform single wall tanks to double wall tanks with applying a second tank
wall inside the existing tank. The System is also suitable for double-wall tanks where on wall was
damaged. The System is approved for both underground and above-ground storage tanks.
The DOPA6N Technology consists of the following:
• An internal layer of epoxy resins to strengthen the underlying steel tank
• A knotted aluminum layer to create the interstitial space
• An external coating of epoxy resins which is chemically resistant to
liquids to be stored in the tank
• In case of stored liquids with a flash point > 55°C, an additional conductive
layer is applied over the external coating to ensure a grounding effect
The Technology holds an approval for its use from DIBt (Deutsches Institut fur Bautechnik)
following tests carried out by TÜV Germany. Furthermore the Italian Ministry of the Interior has
issued a national approval for the system.

The system consists of:
- Base layer applied on a cleand (grit blasted
surface) to repair the steel tank and to block
corrosion
- Inner lining creating an interstice and consisting
of a composite (knotted aluminium, reinforced
epoxy resing layer)
- Conductive top layer
The system is applied directly in the tank by a
defined application process including airless spraying
and rolling.
As a whole system they were tested in terms of
mechanical, chemical and thermical properties by
the German TÜV

Our approach to M&R
 Extend the life cycle and service time of the tank (Mean Time
Between Repair)
 Reduce tank “downtime” during maintenance
 Increase the interval between two internal tank maintenance
interventions (Maximum Internal Inspection Interval)
 Extend the mechanical life of the roof and shell surfaces
 Reduce total maintenance and inspection costs
 Provide a preventive solution for environmental protection,
eliminating any risk of soil pollution caused by leaks from the
tank bottom and reducing VOC emissions

Most common issues leading to aging of storage
tanks
TANK SHELL AND ROOF
1. External corrosion caused by meterological conditions
2. Internal corrosion caused by the vapours from the stored product
3. Possible deformation of the floating roof due to flooding with the stored
product through leaks due to corrosion
4. VOC emissions following the heating of the product due to the
absorption of radiant heat
TANK BOTTOM
1. Internal/external corrosion determined by various factors (such as:
stored product, water, stray currents, bacteria etc.).
2. Stress caused by uneven settlement of the tank
3. Possible contamination of the soil as a result of leakage from the tank
4. Weakening of the inner edge of the stringer
RING WALL
1. High mechanical stress
2. External corrosion caused by bad weather
3. Possible impact on the stability of the tank
CONTAINMENT BASIN
1. Erosion, cracking and deterioration of the flooring
2. Possible contamination of the soil
