The following questions are mainly directed at centrifugal glass wool, aluminum silicate, and PIR. Dear experts, what are the typical thickness specifications for insulation materials used in pipes? For example, in terms of standards and calculations, it’s 30, 40, 50, 60, 70, 80, 90, 100. . . . . . . They all exist, but when making a purchase, are only certain specifications among them commonly used? ? ? For example, 50, 80, 100. . .
Can’t everyone use the internet at work? Is there any expert who can give an answer? Thank you
You should ask the manufacturer about this, right? Give them the insulation thickness and let the manufacturer give suggestions!
The thickness of the insulation material varies depending on the manufacturer. Generally speaking, for pipes ranging from DN15 to DN80, each manufacturer of insulation materials provides corresponding insulated pipes. For pipes with a second layer of insulation or larger diameters, insulation panels are usually used in construction. The thickness of the insulation material varies among different manufacturers; common thicknesses on the market include 25mm, 32mm, 40mm, 50mm, etc. However, the specific specifications and thicknesses required need to be determined by consulting the manufacturer or agent, as this depends on the order quantity and labor costs. As you know, with the same insulation thickness, the more layers of insulation there are, the higher the labor costs will be; thus, there is an economic consideration at play here. Regarding insulation materials, it is recommended to use flexible insulation materials. The main types of flexible insulation materials in use in China at present are those produced by the German company Arals and the Italian company Fulflex; both of these materials can withstand temperatures as low as -200°C. Compared to traditional PIR materials, they result in less heat loss and have a longer service life. What’s more, they are very easy to install and maintain, especially for complex-shaped components. However, their cost is higher than that of PIR materials. Currently, companies such as CNPC, Sinopec, China Resources, Honghua Gas, Huaqi Houpu, Chuan Kong, Hangyang, and Air Liquide use these materials.
