濟南通風管道加工的過程中難免會有問題的發生，下面講解兩個發生比較普遍的問題，從管道傾斜角度和彎頭角度以及管道加工材料方面來看看看吧。
For Jinan ventilation pipe processing, there will inevitably be problems. Here are two common problems, which can be seen from the angle of pipe inclination, elbow angle and pipe processing materials.
1、管道傾斜角度和彎頭角度不正確
1. Incorrect pipe inclination and elbow angle
性能：折疊角不平直；矩形風管的兩個相對平面與兩端不平行；咬人不嚴格；對角線不相等。
Performance: the folding angle is not straight; The two opposite planes of rectangular duct are not parallel to both ends; The bite is not strict; Diagonal lines are not equal.
原因：管道成對平行，相對板的長度和寬度不相等；板材下料放樣設置的不正確。
Cause: The pipes are parallel in pairs, and the length and width of the opposite plate are not equal; The setting of sheet blanking and lofting is incorrect.
影響：會在通風管道上造成不均勻的力，安裝的管道不平直，法蘭墊圈不牢固，并且系統泄漏，從而導致空調負荷損失，導致使用壽命縮短。
Impact: It will cause uneven force on the ventilation pipe, the installed pipe is not straight, the flange gasket is not firm, and the system leaks, resulting in the loss of air conditioning load and the shortening of service life.
措施：展開和下料時，應嚴格限制板材的直角，將板材的長度，寬度和檢查對角線控制在允許范圍內；落料后，管道相對部分的兩塊板應重疊以檢查尺寸精度。
Measures: During unfolding and blanking, the right angle of the plate shall be strictly limited, and the length, width and inspection diagonal of the plate shall be controlled within the allowable range; After blanking, the two plates in the opposite part of the pipe shall be overlapped to check the dimensional accuracy.
2、管道加工材料不符合標準
2. The pipe processing material does not meet the standard
性能：管道表面下沉，側面向外突出，變形明顯；板的表面不平整，厚度不均勻，有明顯的壓痕，裂紋，砂眼，疤痕和生銹。
Performance: the pipe surface sinks, the side protrudes outward, and the deformation is obvious; The surface of the plate is uneven, with uneven thickness, obvious indentation, crack, sand hole, scar and rust.
原因：該材料不合格，不能滿足制造風管的要求。
Cause: The material is unqualified and cannot meet the requirements for manufacturing air duct.
影響：操作期間風管泄漏，空調負荷增加以及風管壽命和性能受到影響。
Impact: air duct leakage, air conditioning load increase, and air duct life and performance are affected during operation.
措施：在制造管道之前，有必要檢查材料出廠合格證書，材料合格證書，外觀厚度等，以確保材料可用。
Measures: Before manufacturing pipes, it is necessary to check the factory certificate, material certificate, appearance thickness, etc. of materials to ensure the availability of materials.
The above is the explanation of the relevant content of the question "Two common problems in the processing of ventilation ducts". I hope you have a new understanding.
