Ventilation duct is a municipal infrastructure for air circulation and reducing the concentration of harmful gases, which is widely used in catering, hotels, industry and agriculture and other industries. In life, we can see ventilation ducts everywhere, and the importance of ventilation ducts is self-evident. Due to the high production cost of ventilation pipes, people pay more and more attention to the maintenance of pipes
Cold and hot insulation
Winter (insulation): prevent the heat loss of the air in the pipeline;
When transporting waste heat steam or high-temperature gas, heat will be emitted into the space, and the indoor temperature will rise;
Prevent scalding when contacting the air duct;
Summer (cold insulation): because the temperature of natural gas transported is lower than that of the surrounding environment, condensation may occur on the outer wall of the pipeline, which will increase the cooling loss of the air duct of the air conditioning system, and condensate droplets will pollute the ceiling and wall, so cold insulation treatment should be done well.
In addition, when the air duct is conveying gas, the air duct shall be derusted, painted with antirust paint, and the dusty gas shall be sprayed with a loss prevention protective layer. When the ambient air humidity is high, the outer wall of the air duct should be treated with anti-corrosion and rust prevention. Only anti-corrosion insulation (cold insulation) can reduce the corrosion phenomenon in the later use process.
How to prevent corrosion?
As the saying goes, "three layers inside and three layers outside", in fact, this is not a joke!
Spraying anti-corrosion process really needs 6 times of finish paint to achieve anti-corrosion!
To sum up, only by carrying out anti-corrosion, thermal insulation and cold insulation can we reduce corrosion in the later use process.
