Tankbouw methode shop built

How does a shop built project work?

We can produce tanks up to 5000 m3 in our Gpi Tanks XL production hall in Groot-Ammers, taking care of everything from start to finish, including production, transport and installation.

As soon as our engineering department has finalised the design, production can begin. Our production hall is equipped with state-of-the-art machinery and resources to help us efficiently construct high-quality tanks to meet your exacting requirements.

Bouwmethode: shop built

We construct tanks layer by layer from bottom to top. Each hull section starts life in the decoiler, where the stainless steel sheet is unrolled in the correct shape. The ends are then welded together. Hull sections are then attached to one another before being passed to the stretcher where they are neatly joined together. Once the hull sections have been joined, they are welded, before returning to the stretcher for the weld seam to be smoothed out, allowing the tank to be finished more efficiently and retain its shape. The final phase, comprising grinding (if required), pickling and passivating, can then begin.

All of our tanks are produced from stainless steel, a strong, low-maintenance and corrosion-resistant material. It is essential to select the correct type of stainless steel, as each application has differing requirements. You can learn more about why we use this material and about the different types in our article on stainless steel. Our experts would be happy to advise and help you to make the right choice for your product.

We are VCA** and VCA Petrochemicals certified and are well acquainted with PGS 29 and PGS 30. We also safeguard quality with a number of other certifications, including ISO 9001, and carry out construction in accordance with NEN-EN-1090 and NEN-EN-14015. Learn more about how we treat safety and quality.
