The air duct in the air duct processing shaft is vertically installed. Due to the small space and inconvenience for future maintenance, the air duct is generally connected with an outer sleeve angle steel flange to increase the firmness and strength of the connection point, and the flange is made into a "well" shape. The hanging bar is directly suspended on the lifting lug of the angle steel flange without additional supports.

風管加工的時候不能在其內部設置加固框或者加固筋，若是加了會對通風管道的質量造成影響。

When the air duct is processed, it is not allowed to set reinforcement frame or reinforcement bar inside it. If it is added, it will affect the quality of the air duct.

濟南風管加工不能使用C型直角插條和S型插條的連接方式，對于一些特殊的通風管道，不能采用按扣式的咬口。通風管道制作完之后，還需要用清洗液進行清洗，達到標準后才能封口。

The connection mode of C-type right angle and S-type inserts cannot be used in Jinan air duct processing. For some special air ducts, snap joint cannot be used. After the ventilation pipe is made, it needs to be cleaned with cleaning solution, and it can be sealed after reaching the standard.

風管加工過程中應減少出現縱向接縫，不能出現橫向接縫，而且通風管道的縫隙處要按照設計潔凈等級要求，然后采用密封膠將其堵嚴，通風管道的板材接縫的密封面要設在通風管道壁的正壓側。通風管道加工過程中要做好防腐蝕措施，管道零件需要經過鍍鋅處理。

During the processing of the air duct, the longitudinal joints shall be reduced, and the transverse joints shall not occur. The joints of the air duct shall be sealed with sealant according to the design cleanliness level requirements. The sealing surface of the plate joints of the air duct shall be set at the positive pressure side of the air duct wall. Anti corrosion measures shall be taken during the processing of ventilation pipes, and pipe parts shall be galvanized.

通風管道制作完畢之后，還要用清洗液進行清洗，只有到達清洗標準之后，才可以及時封口。

After the fabrication of the ventilation pipe, it shall be cleaned with cleaning solution. Only after the cleaning standard is reached, can it be sealed in time.

如果是彩色涂層鋼板通風管道的話，應該保持內壁是光滑的，并且風管加工的過程中，還不能將涂層損壞，若是呈現損壞的部位，需要用環氧樹脂涂刷在外表即可。別的風管加工的過程中，還要做好防腐蝕辦法，不能運用抽芯鉚釘，并且在通風管道零件裝配的時分，這些零件都要經過鍍鋅處理才行。

If it is a color coated steel plate ventilation duct, the inner wall should be kept smooth, and the coating should not be damaged during the processing of the air duct. If the damaged part appears, it needs to be painted on the surface with epoxy resin. In the process of processing other air ducts, anti-corrosion measures shall be taken, and pop rivets shall not be used. In addition, these parts shall be galvanized during the assembly of air duct parts.
