As early as 1970, Xaver Lipp (founder) had the idea for the unique double-fold system, which signified a quantum leap in the field of tank technology and has stood the test in the construction of containers and tanks in innumerable plants to the present day.

 

The system involves steel bands being interlinked by folds giving the inside of the container an edgeless and smooth surface. Using two powerful machines on site, the double-fold system guarantees maximum tightness and stability.

 

Materials

 

A special material, Verinox, was developed by LIPP and won the Baden-Württemberg Innovation Award in 2005. It combines galvanized steel for the outside and stainless steel for the inside of the container. After in-house production, the coiled material is delivered to the construction site. Verinox impresses with a favourable cost-benefit ratio and guarantees lasting reliability. The same tank construction system and materials are used for Biogas Plants construction.
