Transport pipeline in today's bearing objects have an important role  and status, therefore, the pipeline of anti-corrosion insulation  treatment has received increasing attention, today we look at the  ventilation pipe insulation treatment results and significance.
 
When  the air duct to transport the general gas, the black steel duct should  be rust, brush anti-rust paint treatment, the dust can be sprayed with  anti-wear protective layer, when the ambient air humidity is large, the  air duct to be anti- Corrosion, rust treatment. For  the transmission of high temperature, high humidity gas galvanized  steel duct wall should be sprayed phosphating primer or other  corrosion-resistant coating. In the duct to transport high temperature gas or low temperature air,  the outer wall of the duct should be insulated (cold) treatment.
 
The  purpose of the high temperature gas duct is to prevent the heat loss  from the air in the pipeline (in the winter air conditioning system);  the other is to prevent the waste heat or high temperature gas to  prevent the heat emitted to the room and the room temperature , But also to prevent people from exposure to air duct and burned. And  in the summer often due to the temperature of the delivery gas is lower  than the ambient air dew point temperature, the pipe wall will produce  condensation phenomenon. This  will focus on the air conditioning system air duct will increase the  loss of cold, while condensation of water droplets will pollute the  ceiling and wall, it should also be cold insulation treatment.
