Shape of the outer protective metal sheet for the thermal insulation structure
Thread Content
I have the following questions regarding insulation layers of different sizes: For storage tanks (such as those with a capacity of 2000 cubic meters), rock wool is used for insulation, and a layer of galvanized iron sheet is applied on the outside – why does this iron sheet need to be corrugated? The galvanized iron sheet covering the tower (with a diameter of 3 meters) is not shaped in that way; it is simply wrapped around directly.
The thin plate is made corrugated to increase its strength. Insulation support rings are installed every 3-4 meters on tower-type containers, with a relatively short height ； The height of oil tanks is generally between 12 and 15 meters, and no thermal insulation support rings are used; they are made in a corrugated shape to enhance strength. For the insulation layer of oil tanks, I recommend using colored steel plates, which can be used without any need for overlapping.
