(1) Part 4.2 of Eurocode 3 provides principles and application rules for the structural design of vertical cylindrical above ground steel tanks for the storage of liquid products with the following characteristicsa) characteristic internal pressures above the liquid level not less than -100 mbar and not more than 500 mbar 1) ;b) design metal temperature in the range of -50ºC to +300ºC. For tanks constructed using austenitic stainless steels, the design metal temperature may be in the range of -165ºC to +300ºC. For fatigue loaded tanks, the temperature should be limited to T < 150ºC;c) maximum design liquid level not higher than the top of the cylindrical sh
