What is the difference between insulation materials and cooling materials?
Thread Content
Dear seniors, what are the differences between insulation materials and cooling materials in chemical plants? What are the differences in their use during design and construction, and what aspects need to be taken into consideration? I would appreciate your advice!
The insulation material must not allow water to condense on the surface of the equipment.
Insulation materials and heat-insulating materials are both types of insulating materials! There’s no difference!
Both are insulating materials with very low thermal conductivity; however, insulation materials have fewer restrictions regarding the temperature they can withstand, while thermal insulation materials have a higher tolerance for heat
Insulation materials are chosen to be heat-resistant and non-flammable, but not waterproof; examples include aluminum silicate. For cooling purposes, materials with air pockets in their structure are used – these do not require to withstand high temperatures and are waterproof. In the past, foam agents were used, but nowadays cooling foams are more commonly employed for this purpose.
They are both materials with good thermal insulation properties; one can withstand high temperatures while the other can withstand low temperatures
Insulation work is a bit more complicated, as it requires the installation of a moisture barrier.
Insulation materials are used to create a barrier that isolates the object being insulated from the outside environment. Insulation materials are also employed in cold environments. As a simple example, everyone is familiar with that foam-like material; it’s the one used to line the wooden boxes in which ice pops are sold. Later on, in order to save energy, buildings began to use this material as well, as it can provide insulation. However, it is flammable, so it is no longer used in buildings today. Instead, fire-resistant materials such as rock wool and glass wool are used. All insulation materials have standards to meet – parameters such as thermal conductivity, combustion tests, and heat loss must all be checked by designated testing agencies before such materials can be approved for use in the construction industry

Different requirements regarding thermal conductivity; 3. In the case of cold insulation, bonding is necessary with no gaps allowed, while this is not required for heat insulation; 4. Different construction methods; 5. Different materials
Generally, the material used for low-temperature pipelines is stainless steel. For temperatures below -100 degrees Celsius, glass bricks are typically used for insulation, with asphalt-covered glass cloth applied on top; an aluminum sheet or galvanized iron sheet serves as the protective layer on the outermost side.
Different materials require different construction plans and methods.
