Tank Construction Double-Seam System

The Double-Seam system originated in Germany, its creator is Mr.Lipp, a German engineer. The first silo using the Double-Seam system was constructed in 1972 by LIPP GmbH. Today, this system has proven itself successful thousands of times around the globe for 46 years.

Building a steel tank with the Double-Seam system requires certain silo contruction equipment. In the tank construction process, the edges of steel strips are folded over together twice by a special channel seaming machine. The steel strips are connected in such a way that even the most aggressive materials inside the tank cannot find any surface to attack, resulting in high corrosion resistance and maximum leak tightness.

The silo’s maximum safety can be achieved by using the Double-Seam system. The unique structure of the Double-Seam not only guarantees the storage tank’s leak-tightness but also makes sure the tank can possess great stability, even the largest tanks can resist huge horizontal pressure.

Besides, the installation is fast, efficient, and economical. The construction equipment is easy to transport due to its light weight and small size. So tanks and silos can be easily constructed by the machines on-site in the desired size and with a variable diameter.
