Self-Supporting Stainless Steel Roof for Whey Tank

The dairy company Mertens in Germany owns two new stainless steel tanks with self-supporting stainless steel roofs.

Whey tank in stainless steel

The industrial tank with about 800 m³ capacity is equipped with a wall bushing, 8 inches suction and filling port as well as fixed stairs. The tank is used to store whey and other liquids of the dairy company.

Stainless steel roof for storage tank

The self-supporting stainless steel roof has an incline of 10°. The roof is composed of an inner and outer ring. The outer ring equalises the diameter of the tank (11 m), whereas, the inner ring has a diameter of 1 m. The outer ring is fixed on top of the tank and lies lower than the inner ring. Thus, the roof gets the inclined shape. Between the rings, Z-profiles are the basis for the roof and support the stainless steel shells which are slotted and bolted. The roof has an inspection hole.

Buffer tank in stainless steel

The second stainless steel tank with a diameter of 3 m is used as a buffer tank. It is furnished with the same components and the stainless steel roof.
