The processing technology of ventilation pipe is to mature and determine the performance of the pipe, and make a good technical decision on the purification of air conditioning ventilation pipe for engineering vibration. Up to now, the blue link of production plate and angle of zinc iron iron, and the quality of the pipe can not be guaranteed occasionally. In the investigation report, it is pointed out that in a thousand years, if the air leakage of grinding treatment is not more than 50%, the heat is also more than 13%.
In fact, building ventilation system engineering is a part of the actual construction, which arranges the ventilation pipes effectively, efficiently, efficiently, and has the function of natural ventilation and natural ventilation through the requirements of natural wind. But in ventilation design and engineering, attention should be paid to the quality of ventilation pipes, which directly affects the ventilation and ventilation function of the whole building. The processing technology of the ventilation channel is relatively high, so the larger one can be selected as far as possible in the ventilation channel of the East building. But the company, this kind of company is more advanced in the production equipment, can guarantee the whole ventilation pipeline project. Because in the production process, the ventilation pipe can be used directly, and can be used before the large-scale development. China's air conditioning industry is the "purification air conditioning" started in the mid-1970s, when a new topic should pay attention to a new topic. Of course, in engineering application, the ventilation pipe is also very heavy, the cleanliness and confidentiality of the pipe directly affect the operation of the whole purification system. Air pressure, air volume, air distribution, cleanliness, operation speed and noise of the system will be affected.
Ventilation pipe is a kind of metal or non-metal pipe used for ventilation and air conditioning of industrial and civil buildings. They are a kind of municipal infrastructure. The ventilation pipes in Jinan allow the air to flow and reduce the concentration of harmful gases. Most of the ducts are made of duct processing equipment. However, for various reasons, it may cause problems in the manufacture of trachea.
The processed materials are unqualified.
1. Performance: uneven surface, uneven thickness, indentation, crack, trachoma, scar and rust spot are obvious; air duct plane sinks, one side of Jinan ventilation duct is protruding, with obvious deformation.
2. Effect: increased air leakage and air conditioning load during operation will affect the wind power and performance.
3. Reason: the material is unqualified, which can not meet the needs of air duct production.
4. Measures: before using the air duct processing equipment as the air duct, it is necessary to check the material certificate and the thickness of the material to ensure that the material is available.
