Insulation thickness of storage tank
Thread Content
I just read some guidelines regarding the insulation of pipes and equipment. Regarding the insulation thickness for equipment, I saw that there are numerous calculation formulas. Is there any kind of empirical thickness value that can be used as a reference, or is there a table showing typical insulation thicknesses based on different temperatures? I currently have two horizontal storage tanks: one with a 1600 mm diameter at 110 degrees, and another with a 1200 mm diameter at 75 degrees. Could you advise me on the appropriate insulation thickness to use? Is 80mm okay? (I’ve just started working in design and don’t have much experience yet.) Thank you all for your help. It would be great if you could tell me under which standards I can find this information; I’ll also need to deal with insulation design for piping systems in the future.
The selection of the insulation thickness is closely related to the choice of insulation material; it also depends on specific processes, such as the allowable temperature drop and the available operating space. It should be calculated, unless there is practical experience.
The thickness of the insulation has little to do with your diameter; what you should consider is the operating temperature and what kind of insulation material you want to use
Generally, the lower the operating temperature of a device, the thicker the insulation required
The insulation thickness is related to both the temperature difference between the inside and outside, as well as the type of insulation material used; it cannot be explained in just a few words, as it requires technical calculations.
Thermal insulation requires calculations to determine the thickness. The technical requirements should specify the surface temperature of the insulation layer. The heat transfer coefficient of the chosen insulation material is the most important parameter, as it affects both the insulation efficiency and the thickness of the insulation layer; the lower the heat transfer coefficient, the thinner the insulation layer required. The experience does not fully meet the requirements of specific equipment.
Calculate using that standard or method?
Reference can be made to the \"Technical Specifications for Insulation of Petrochemical Equipment and Piping\" SH3010
It is generally determined based on the properties of the insulation material and the process requirements.
My container is designed for low temperatures; the material used is polyurethane foam, with a thickness of 80mm. You can use this as a reference when making your choice
It depends on whether your equipment has specific insulation requirements. For most equipment or pipelines, the requirements relate to surface temperature or heat loss; of course, there are also some devices for which a temperature drop is required. Therefore, different approaches must be taken depending on these various requirements
