Regarding the thickness of pipeline insulation
Thread Content
Dear friends: For the insulation of pipes, rock wool is generally used for this purpose. The required thickness of the insulation layer shall be determined in accordance with the relevant technical specifications. However, there is a question: if the pipe requires 110 mm of insulation, and a single layer of rock wool provides 55 mm of insulation, then two layers would be needed. But is it necessary to take into account factors such as the compressibility of rock wool? In other words, does the insulation material need to be more than two layers thick in order to meet the insulation thickness requirements for the pipes? Thank you!
Should rock wool be banned from use? It poses a serious threat to health.
Now aerogels are used everywhere~ Perlite is no longer used
I’ve never heard that rockwool is not allowed to be used; I have, however, heard that asbestos gaskets are no longer permitted
According to GB50126, when using a thermal insulation material and the insulation thickness exceeds 100 mm or the heat insulation requirement is more than 80 mm, it is necessary to apply the insulation in multiple layers, with each layer having the same thickness. In the current situation, multi-layer installation should have been taken into account during the design phase; you can simply apply the insulation in two layers, and there should be no problems. Also, pay attention to the requirements regarding installation.
