Non-combustible insulation material for steam pipes
Thread Content
The temperature of the steam pipeline is around 300 degrees, with a DN150 diameter. Since it passes through a fire wall, non-combustible insulation material is required; please recommend the most common type.
How is aluminum silicate? We use it for insulating our steam pipes.
At 300 degrees, normal insulation materials are no problem. Rock wool, glass wool, and aluminum folic acid all work. In addition, sleeves need to be installed, and the gaps should be sealed using oil-cotton asphalt and expanded asbestos cement.
