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%.

　　建筑通風系統工程實際上是在實際施工中，布置通風管道的一部分，有效地、地、地、地，通過自然風的要求具有自然通風和自然通風的功能。但在通風設計和工程中應注意通風管道的質量，它直接影響到整個建筑的通風和通風功能。通風道的加工工藝較高，因此可以在東樓通風道中盡量選用較大的通風道。而公司，這種公司在生產設備上比較，可以保證整個通風管道工程。因為在生產過程中，可以直接使用通風管，可以在大規模發展前使用，的空調行業是在上世紀70年代中期開始的“凈化空調”，當一個新課題要注意一個新課題。當然，在工程應用中，通風管道也確實非常沉重，管道的清潔度和保密性直接影響整個凈化系統的運行。系統風壓、風量、氣流組織、清潔度、運行速度和噪音都會受到影響。

　　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.

　　通風管道是用于工業和民用建筑通風和空調的金屬或非金屬管道。它們是一種市政基礎設施，濟南的通風管道允許空氣流動，降低有害氣體的濃度。風管大部分由風管加工設備制成。然而，由于各種原因，它可能會造成問題的制造氣管。

　　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.

　　加工的材料不合格。

　　The processed materials are unqualified.

　　1. 表現:表面不平整、厚度不平整、壓痕、裂紋、沙眼、疤痕、銹斑明顯;風管平面下沉，濟南通風管道一側突出，變形明顯。

　　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. 效果:運行中漏風增加，空調負荷增加，影響風力和性能。

　　2. Effect: increased air leakage and air conditioning load during operation will affect the wind power and performance.

　　3.原因:材質不合格，無法滿足風管生產的需要。

　　3. Reason: the material is unqualified, which can not meet the needs of air duct production.

　　4. 措施:使用風道處理設備做風道前，必須檢查材料的合格證和材料的厚度，確保材料可用。

　　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.
