What is the example of filling in the inspection record data sheet of duct insulation concealed engineering?

1, air conditioning duct insulation has been completed according to the drawings.

2. Thermal insulation adopts 1200*600*30 glass fiber cotton board. Its material, density and specifications all meet the design requirements of Baidu. Plate construction is dense, without cracks, gaps and other defects, and the surface is smooth, and the deviation meets the specification requirements.

3. Connect the air duct parts and equipment surfaces with heat insulation nails, with a bottom surface of not less than 16, a side surface of not less than 1 and a top surface of not less than 8. The insulation nails are evenly distributed, firmly combined and without falling off, which meets the specification requirements.

Commonly used pipeline insulation materials:

1. Rock wool shell. Used for thermal insulation of various pipelines, including oil, electricity, heating, industry and so on. , mainly used for heat preservation, heat insulation and prevention of pipeline freezing crack. ?

Applicable temperature: < 350℃ ~ ≤ 600℃?

Suggested temperature: 350℃

2. Glass wool tube shell. Used for integral insulation of various pipelines (including refrigeration, hot air, hot water, etc.). ), widely used in heat pipe, air conditioning, refrigeration equipment insulation.

Applicable temperature: ≤454℃

3. Aluminum silicate pipe shell. Used for electric boiler high-temperature pipeline, thermoelectric high-temperature steam pipeline and chemical high-temperature steam pipeline.

Applicable temperature: ≤ 1000℃. (Used for high-temperature pipes in power industry)
