Your vision. Our solution.
Prefabrication and pipe installation
Pipe spools, modules and steel structures welded in our workshop in Smederevo, Serbia, and installed on site by our own teams — for data centres, energy and oil & gas projects in Germany, the Netherlands, Belgium, Denmark, Finland, Italy, Qatar and Saudi Arabia.

What a piping package manager checks first — welding processes, execution class, pressure-equipment approval, NDT, surface protection and the shop behind them.
Every figure on this sheet is taken from our certificates, our project data and our published facility plans.
