摘要

Vertical double-walled flat-bottomed tank has an oval cross-section. The tank cylinder (1) and the tank bottom (2) are made from rigid outer and inner walls flexibly connected to each other by a rigid spacing element. The tank roof (3) is single-walled and is curved outwards with a radius corresponding to the static requirements and has a rim pulled downwards with a smaller radius.
