How is pipe insulation done to prevent frost damage?
Thread Content
According to the design specifications, metal wire mesh is used to insulate pipes and prevent frost damage; does this mean that it’s sufficient to place a layer of metal wire mesh around the pipes, without the need for any insulating material? Is there any standard that provides detailed instructions on this? Thank you!
If cooling is required, the material needs to be wrapped up
The wire mesh is used to secure the insulation material, on the outside of it.
One should pay attention to a comprehensive interpretation of insulation; focusing only on the mesh while ignoring its function. There are many materials used for insulation, and this seems to be a method for fixing insulating materials. It could be fixed bulk insulation bricks (expanded perlite bricks) or sprayed insulation material. For reference.
It’s impossible for just wire to do the job, haha. There must be a thermal insulation layer, and there are reportedly new materials that can reduce the thickness of this insulation. You can inquire with the manufacturers who carried out the construction of Yamal Phase 1 and Phase 2; maybe they have solutions in case of emergencies
It prevents scalding and helps with heat dissipation; I designed my project in this way as well, and it works quite well
It is not necessarily for heat protection; PP stands for Personal Protector, and it is used to protect people. Such protection is necessary for pipelines that are cold or hot, as well as those that might be accidentally struck by people or tools, in order to remind people to be especially careful with these pipelines.
For insulation pipes, we generally use polyurethane foam plastic
Wire mesh should be used as a substitute for aluminum or galvanized iron sheets, which are conventional insulation materials
