Workshop fabricated steel tanks - Part 4: Vertical cylindrical single skin and double skin tanks for the aboveground storage of flammable and nonflammable water polluting liquids other than for heating and cooling of buildings; German version FprEN 12285-4:2023
Abstract
This document specifies the requirements for metallic shop fabricated shop fabricated cylindrical vertical steel tanks, single and double skin for the aboveground storage of water polluting liquids (both flammable and non-flammable) within the following limits: - from Ø 1250 mm up to Ø 4 000 mm inner tank nominal diameter and, - up to maximum overall length of 6 times the nominal inner tank diameter and, - tank possible to be divided from 1 to 5 compartments, - for liquids with maximum density of up to 1,9 kg/l and, - with an operating pressure (P0) of maximum 50kPa (0,5 bar (g)) and minimum - 5 kPa (- 50 mbar (g)) and, - where double skin tanks with vacuum leak detection system are used the cinematic viscosity of the stored media shall not exceed 5×10-3 m²/s. This document is applicable for normal ambient temperature conditions (-40 °C to + 50 °C). Where temperatures are outside this range, additional requirements need to be taken into account. This document is not applicable to tanks used for storage and/or supply of fuel/gas for building heating/cooling systems, and of hot or cold water not intended for human consumption, nor to loads and special measures necessary in areas subject to risk of earthquakes. This document is not applicable for the storage of liquids having dangerous goods classes listed in Table 1 because of the special dangers involved.
