Jinan air duct processing common plate flange is mainly connected with the air duct by corner code, flange clamp and flange. Although the cost of this air duct is low (the consumption of angle steel is reduced, and the labor consumption of making angle steel flange is reduced), it is not as good as angle steel flange in practical application, and the air leakage rate is also large, so it must be processed by machine tool. Manual manufacturing is difficult to achieve its production, which is usually only used for fresh air system, air conditioning system, etc. The exhaust system is usually connected with angle steel flange, but the civil air defense project is not allowed to use ordinary flange plate. What is the basis for the processing and manufacturing of ventilation pipe in Jinan? Now, let's take a closer look. I hope I can help you.

濟南通風管道廠家發現，在加工制造風管的過程中，對材料的要求相當苛刻。當風道表層為鋁箔時，為了保證表層不容易損壞，規定了鋁箔的材質和厚度，規定了鋁箔與增強材料復合的風道表層鋁箔的厚度。

Jinan ventilation duct manufacturer found that in the process of processing and manufacturing air duct, the requirements for materials are quite strict. When the air duct surface layer is aluminum foil, in order to ensure that the surface layer is not easy to be damaged, the material and thickness of aluminum foil and the thickness of aluminum foil on the air duct surface layer composed of aluminum foil and reinforcement are specified.

非金屬風管材料發展迅速，種類繁多，因其特點和優勢而得到廣泛應用。為確保使用安 全，根據工程需要，建議由這些材料制成的風管應具有不燃性或阻燃B1燃燒性能，面層必 須為不燃性材料。根據我國多年的工程應用實踐和產品現狀，規定了熱敏膠帶和壓敏膠帶的剝離強度試驗低值和鋁箔厚度，要求膠帶寬度不小于50毫米，以防止所用膠帶不能滿足管壁密封強度和風管的使用壽命。熱敏膠帶的優點是它依靠熱熔粘合，只要不加熱，粘合表面在常溫下固化，并且具有牢固的粘合強度。

Non metallic air duct materials have been widely used because of their characteristics and advantages. In order to ensure safe use, according to the needs of the project, it is recommended that the air duct made of these materials should have non combustible or flame retardant B1 combustion performance, and the surface layer must be non combustible material. According to many years of engineering application practice and product status in China, the low value of peel strength test and aluminum foil thickness of thermal tape and pressure-sensitive tape are specified, and the tape width is required to be no less than 50mm, so as to prevent the tape used from failing to meet the sealing strength of pipe wall and the service life of air duct. The advantage of thermal tape is that it relies on hot melt bonding. As long as it is not heated, the bonding surface is cured at room temperature and has firm bonding strength.
