For large silos with a capacity of 500 m3 or more mere bolting of silo segments will reach technical and economical limits. Welding of the segments becomes necessary. The Panel Tec design complies with this requirement: after manufacture of the individual silo roof, silo cone and cylindrical silo shell segments in the workshop additional flanges are welded to the segments in order to facilitate and accelerate the assembly on site later on. The maximum height of the individual silo segments is 2 m which allows transport to site in standard containers, facilitates bolting at site and makes automated welding possible. For vertical assembly of the silo shell sections the silo may either be suspended from a crane or positioned horizontally. When all silo segments have been bolted the joints in the interior of the silo are welded completely. The welding process is carried out inside the silo protected from weather influences after the silo has been put into a horizontal position. The automated welding process downhand ensures high-quality weld seams which then form the supporting structure of the silo. Another advantage of the flanged joint is the increased buckling resistance.
The Panel Tec design offers beyond the optimised material utilisation the advantage of significantly reduced transport costs due to the fact that standard trucks can be used instead of heavy-load vehicles.
