Even during extremely high water, your stock of oil will still remain safe from flooding / No swelling or distortion
Selters (hds).- From the surprisingly numerous 'floods of the century' in recent years, communities in areas threatened by flooding have drawn the obvious conclusions. They insist on an oil storage facility that is safe from flooding. To achieve this, a tank must fulfil two criteria: First a tank may not swell up and second it may not become dented under the external pressure from the floodwater. The reason why: Compression will always lead to oil escaping from the venting line.
Company: Schütz GmbH & Co. KGaA, of Selters, has developed a tank of 1,000 litres capacity with double-walls for safety in areas prone to flooding, and has submitted it for official approval. Two tension booms attached to special plugs set into a concrete baseplate anchor each tank. It follows that the foundations must be capable of safely withstanding the lifting force of the floodwater. Concrete of a B25-C25 strength category and of a thickness of 15 cm generally fulfils this requirement.
The floodwater tank itself is more thick-walled than the normal type and when static is capable of coping with both pressure from inside and outside. The permitted flooding height may be 2.50 metres from the tank's base. Or – for a 1.50 metre high tank – 1.00 metres from its top. The tank-within-a-tank container will therefore maintain its original shape even at an external pressure of 0.25 bars.
This tank completes the existing double-walled range from Schütz with their various dimensions and sizes between 750 and 1,500 litres.
