What materials are used for pipe insulation and cooling, and how is the thickness calculated?
Thread Content
-What material is suitable for insulating low-temperature pipes at 196°C? Is there a formula for calculating the thickness required? It’s for laboratory pipelines on a small scale. For high-temperature pipelines at 250°C, is rock wool a suitable choice for now? I would like to ask everyone for advice.
For insulation, aluminum silicate offers the best results
According to the SH3010 standard, the minimum operating temperature for polyurethane is -80°C; it seems that it cannot be used in my application conditions
I’m not sure which one is better among aluminum silicate, rock wool, and glass wool (it seems that glass wool has a relatively low operating temperature)
I’m not sure which of aluminum silicate, rock wool, and glass wool is the best choice – would using aluminum silicate be too wasteful?
For the piping, a stainless steel lining with a fluoroplastic coating can be used; the fluoroplastic material itself has the advantage of a low thermal conductivity, which enables effective insulation. Pearl sand can be used inside the jacket to provide additional cooling effects! There have also been exchanges of equipment in this area recently!
Let me introduce fluorine materials. The embrittlement temperature for PTFE is -180 to -195 degrees, while that for F46 is -260 degrees
Since it’s work done in a laboratory, it can’t be too complicated, and the piping is already installed – isn’t the jacket lining not very convenient? I plan to use expanded foam glass, but I’m not sure about the thickness. . .
Foam glass foaming – I’ve never worked with that before! It’s hard to be aware of it
