Vitreous and porcelain enamels - Design of bolted steel tanks for the storage or treatment of water or municipal or industrial effluents and sludges; German version EN 15282:2007
This European standard establishes the requirement for the design and use of vitreous enamel coated bolted cylindrical steel tanks for the storage or treatment of water or municipal or industrial effluents and sludges.
This European standard applies to the design of the tank and any associated roof and gives guidance on the requirements for the design of foundation.
This European standard applies where:
a) the tank is cylindrical and symmetrical on plan and is mounted on a load-bearing base substantially at or above ground level;
b) the multiple of the tank diameter in meters and the wall height in meters has a value within the range 5 to 500;
c) the tank diameter does not exceed 100m, and the total wall height does not exceed 50m;
d) the stored material has the characteristics of a liquid exerting negligible friction force in the tank wall; the stored material may be undergoing treatment as part of a municipal or industrial effluent treatment process;
e) the internal pressure above the liquid does not exceed 50 kPa and the internal partial vacuum above the liquid does not exceed 10 kPa;
f) the walls of the tank are vertical;
g) the floor of the tank is sbustantially flat at its intersection with the walll; the floor of the tank may have a rise or fall built in to allow complete emptying of the tank contents.The slope should not exceed 1:100;
h) there is negligible inertial and impact load due to tank filling;
i) the minimum thickness of the tank shell is 1,5 mm;
j) the material used for the manufacture of the steel is carbon steel; (tanks constructed of sheets made from aluminium or stainless steel are outside the scope of this European Standard ),
k) the temperature of the tank wall during operation is within the range -50℃ to +100℃ under all operating.
This European standard also gives details of procedures to be followed during site installation and for inspection and maintenance of the installed tank.
It does not apply to chemical reaction vessels.
It does not apply to tanks fitted with floating roofs.
It does not cover resistance to fire.
