FIELD: construction, particularly to produce and install metal tanks adapted for liquid and powder material storage.
SUBSTANCE: method involves manufacturing flat blank made as wide band and strip air-tightly connected to band surface; shaping the blank to form cylindrical body by rolled blank bending in folding machine and connecting overlapped longitudinal blank edges with each other; reinforcing ready body with stiffening ribs; forming hollow stiffening ribs by strip and underlaying band section deformation. Rolled blank is bent through 63° to horizontal body axis. Hollow rib ends at rolled blank edges are created in flexible releasable members, which are sealed to strips and underlying band sections.
EFFECT: increased quality of tank production.
