薄钢板法兰风管 ：

　　Thin steel plate flange air duct:

　　薄钢板法兰应采用机械加工，且平直，机械应力造成的弯曲度不应大于5‰。

　　Thin steel plate flanges should be machined and straight, and the bending caused by mechanical stress should not exceed 5 ‰.

　　薄钢板法兰与风管连接时，宜采用冲压连接或铆接，铆接点间距宜为120mm~150mm。

　　When connecting the thin steel plate flange to the air duct, it is advisable to use stamping connection or riveting, and the distance between the riveting points should be 120mm~150mm.

　　薄钢板法兰弹簧夹的材质应与风管板材相同，形状和规格应与薄钢板法兰相匹配，厚度不应小于1mm，且不应低于风管本体厚度，长度宜为130mm~150mm。

　　The material of the thin steel plate flange spring clip should be the same as the air duct plate, and the shape and specifications should match the thin steel plate flange. The thickness should not be less than 1mm and should not be less than the thickness of the air duct body. The length should be 130mm~150mm.

　　角件与风管薄钢板法兰四角接口的固定应稳固紧贴，端面应平整，相连处的连续通缝不应大于2mm，角件的厚度不应小于1mm及风管本体厚度。

　　The fixing of the corner piece and the four corner interface of the thin steel plate flange of the air duct should be stable and closely adhered, the end face should be flat, and the continuous through seam at the connection should not exceed 2mm. The thickness of the corner piece should not be less than 1mm and the thickness of the air duct body.

　　法兰接口位置密封材料 ：

　　Sealing material for flange interface position:

　　通风管道法兰接口位置应采用厚度为 22×4 、 25×4 、 24×5 、 25×5 的闭孔橡塑胶条和环保型聚氨酯机械密封。

　　The flange interface of the ventilation duct should be sealed with closed cell rubber strips and environmentally friendly polyurethane mechanical seals with thicknesses of 22 × 4, 25 × 4, 24 × 5, and 25 × 5.

　　建议根据具体的应用场景选择合适的法兰接口厚度和密封材料，以确保通风管道的连接强度和密封性能。

　　It is recommended to choose the appropriate flange interface thickness and sealing material according to the specific application scenario to ensure the connection strength and sealing performance of the ventilation duct.
