Layout diameters (m) Layout with single sections Layout with double sections A special study is required for: - Tanks less than 7.00 m in diameter, which require a “hybrid” arrangement (sections of different sizes), - Tanks more than 30.00 m in diameter, which require stabilization or specific structural reinforcements. Our design offices will be delighted to help you with any technical questions. The stresses on the end stops must be evaluated according to: - the geographical area where the structure is situated, - the cladding on the structure (no cladding or covered with nets or canvass sheets).
