Double-wall tanks
Construction of double-wall stainless steel tanks
Gpi constructs double-wall tanks according to customised design specifications. A double-walled tank is understood to be a tank which has an ‘extra’ tank built around it. A double wall may be required for the storage of hazardous fluids.
The construction of a double wall does away with the need for a drip tray. Tanks with exterior insulation and an additional casing also fall under the double-walled category.
Our extensive experience in designing and manufacturing double-wall tanks spans over 25 years and includes using high-quality materials such as stainless steel and other premium alloys.
The experienced constructor of double-walled tanks
With more than 25 years of expertise, we have successfully designed and built double-wall tanks for diverse industries, including petrochemicals and dairy.
Our deep understanding of the processes ensures we deliver products that meet the highest standards.
Do you have any questions about our stainless steel double wall tanks?
High-quality double-walled tanks
For above-ground storage of hazardous substances that pose soil contamination risks, tanks must feature a drip tray or a double casing equipped with a leak detection system.
The specific requirements depend on your permit, which is influenced by the municipality, province, or other issuing authorities. Compliance with these regulations ensures your tank adheres to necessary standards, such as Dutch Kiwa guidelines.
We provide advice and support to ensure that the storage of your products meets all the necessary guidelines for hygiene, safety, sustainability and convenience.
We construct double-walled tanks in line with all relevant standards, including:
- Kiwa BRL-K756/03 (Netherlands)
- Kiwa BRL-K796/02 (Netherlands)
- NEN-EN 12285-2 (Netherlands)
- Vlarem (Belgium)
- DIN 6618-2 (Germany)
- UDT (Poland)
- UKCA (United Kingdom)

Double wall tanks with leak detection
We offer double-walled tanks with integrated leak detection systems, eliminating the need for a drip tray.
Electronic leak detection
A light or audio signal can be used to indicate whether there is a leak in the inner tank wall. Its functioning must be regularly inspected by a BRL K903-certified company every year.
Leak detection pot system
A fluid in the partition indicates a leak through either a drop in fluid level or a colour change.
Depending on the variant chosen, the fluid level will fall, or the colour of the fluid will change. You can check the pot with fluid every month yourself.
Insulation in double-walled tanks
Thermal insulation is essential for processes like pasteurization or fermentation, which require heating and chilling. We utilize mineral wool, PIR, and PUR insulation materials, with advice from our experts to determine the best option for your application. Tanks are fabricated from stainless steel, with insulation typically enclosed in aluminium wall panels.
Stainless steel: double-walled tanks in stainless steel
All our double-walled tanks are constructed from stainless steel, offering variants such as 304(L) and 316(L). High-quality alloys like duplex stainless steel are also available. Stainless steel is chosen for its corrosion resistance, long lifespan, and minimal maintenance needs.
Where do we build double-walled tanks?
We operate production facilities in Lopik and Groot-Ammers. Depending on transportation options, tanks are constructed at these locations, with larger units shipped directly from Groot-Ammers. If transportation is not feasible, on-site construction is available.
FAQ
What are the primary benefits of a double-wall tank?
Double-wall tanks offer enhanced safety for storing hazardous fluids by including an extra layer of protection, eliminating the need for a drip tray, and reducing the risk of environmental contamination.
Why is stainless steel the preferred material for constructing double-wall tanks?
Stainless steel is chosen for its corrosion resistance, long lifespan, and minimal maintenance needs. It ensures durability and maintains high-quality performance even under harsh conditions.
Can you customize double-wall tanks according to specific industry needs?
Yes, we design and manufacture double-wall tanks according to customized specifications, catering to various industries such as petrochemicals, dairy, and more, ensuring compliance with industry standards and regulations.
