Let’s discuss what other requirements there are for the insulation and protection boxes of instruments that require steam tracing. 1) The instrument box should be equipped with a thermal insulation layer to ensure that the temperature inside the insulation box is not lower than 10 degrees under the lowest outdoor ambient temperature conditions. 2) Tracing steam specifications: 1.0MPa saturated steam. 3) With Φ8 stainless steel or copper heating coil and corresponding straight through plate union.
1. Specifications of heating steam: Saturated steam above 0.4MPa is sufficient. 2. The sealing of the box should be based on the structural conditions. 3. It is best not to open the window.
Is it inconvenient to read the meter without opening the window? If the window is opened, what are the requirements for the window?
Increasing the window will increase the chance of damage to the insulating box. There should be requirements on the material of the insulating box, whether it is fiberglass or other.
Although I know about fiberglass, I have never used it. We generally use galvanized steel sheets and aluminum alloy materials. For galvanized steel sheets and aluminum alloys, what are the requirements for material thickness, and are there any requirements for withstanding external forces?
I hope this can be discussed. I also encountered this problem last year, and the insulation effect of some boxes was really not good. What requirements should be followed in terms of form selection? For example, when should a 45-degree cover be used, and when should a front-opening door be used? Material requirements? Mezzanine requirements, etc.?
