<p>The reservoir is made from two C-section profiles (1, 11), one with extended edges closed to form a partition (2), and a number of U-section profiles with convex sides (4, 5), all e.g. of steel. The edges of the second C-section profile (11) and of all the U-section profiles are turned in to facilitate welding of the profiles together to form a single reservoir with the weld seams extending along the whole of their generating surfaces. The ends of the profiles are closed by welded covers, and the partitions can have holes in them to connect the different compartments of the reservoir.</p> |
