What are the insulation and cooling materials used for chemical process pipelines? What are the advantages and disadvantages of each material, and what is their price? I searched online, but it seems I can’t find any detailed information. Is there any detailed material on this topic? Thanks
There are many varieties. The insulation material we use at high temperatures on our stoves is aluminum silicate; for applications with lower temperatures such as steam and hot water, rock wool is used ； Previously, polystyrene foam was used for insulation, but its performance wasn’t good. Now, polyurethane foam is being used instead; it forms well and has a certain degree of elasticity, which is beneficial for insulation work and results in better insulation effects.
There are many insulating or cooling materials used in the chemical industry; theoretically, almost all lightweight, porous materials can be used for insulation or cooling purposes. It’s simply a matter of meeting insulation requirements and preventing condensation through air isolation. The commonly used insulation materials are mainly centrifugal glass wool, silicates, and polyurethane foam. Insulation materials include rubber-plastic foam, among others. The key factors are the application scenario, the temperature of the medium, the requirements regarding corrosion resistance, etc. Different materials should be chosen depending on the specific circumstances; there is no one-size-fits-all solution
In fact, in addition to insulation, additional protective materials are also needed, such as anti-corrosion coatings; in areas where there is no open flame or similar, asphalt can be used for coating.
In what criteria can one find a description of the response?
For insulation, we have used rock wool pipes, foam boards, aluminum silicate, and similar materials here. Insulation is generally achieved by spraying polyurethane foam; just a couple of days ago we insulated two condensers. The price of polyurethane here is already 2,000 yuan per cubic meter. It also depends on the situation; for outdoor cooling or insulation, water-resistant materials need to be considered.
