The new process of ordinary plate flange air duct connection is to use the basic principle of spray welding to form flanges on both sides of the air duct, and then connect the air duct according to the flange angle iron and flange clamp. A new processing technology.

①因為法蘭和空氣管集成,空氣管的抗壓強度進一步提高,和法蘭的凈重是顯著降低。每個插座平均值為80%的不銹鋼板，直接成本顯著降低;

① Because the flange is integrated with the air pipe, the compressive strength of the air pipe is further improved, and the net weight of the flange is significantly reduced. The average value of each socket is 80% of the stainless steel plate, which significantly reduces the direct cost;

如何使通風管道的效用更大化

How to make the ventilation duct more effective

②因為法蘭和空氣管集成,通風的隱患的四條邊法蘭從結構中移除。根據在法蘭周圍選用新型橡膠密封件和在法蘭兩側使用延展性夾鉗或選用實際效果更強的頂絲夾鉗，實際效果對風管的密封性能更可靠。具體檢查時，通風量增大了小角鐵圈法蘭的1/3;

② Because the flange is integrated with the air pipe, the four side flanges of the hidden danger of ventilation are removed from the structure. According to the selection of new rubber seals around the flange and the use of malleable clamps on both sides of the flange or the selection of jackscrew clamps with stronger practical effect, the actual effect is more reliable for the sealing performance of the air duct. During specific inspection, the ventilation volume increased by 1/3 of the small angle iron ring flange;

③它簡化了復雜的角鋼生產過程(鍍鋅扁鋼)法蘭,并消除大量的體力勞動,大大提高工程建設的效率高。實踐經驗表明，采用普通板環法蘭，制作安裝各插座，可節省綜合人工時間50%左右。

③ It simplifies the complex angle steel production process (galvanized flat steel) flange, eliminates a lot of physical labor, and greatly improves the efficiency of engineering construction. Practical experience shows that using ordinary plate ring flange to make and install sockets can save about 50% of the comprehensive labor time.

隨著我國的社會經濟發展已進入現代化的后半段，傳統的高能、高耗能的制造方法已不能再納入可持續發展概念的規定。節能降耗是我國社會經濟發展的必然趨勢。它是化工行業發展趨勢的初始驅動力。根據國外的經驗，政府部門對環境保護非常重視，大規模的資本投資一般發生在現代化的中后期。這一環節的社會經濟發展已進入穩定環節，提高居民生活質量和改善自然環境已成為社會發展的。

As China's social and economic development has entered the second half of modernization, the traditional high-energy and high energy consumption manufacturing methods can no longer be included in the provisions of the concept of sustainable development. Energy saving and consumption reduction is the inevitable trend of China's social and economic development. It is the initial driving force of the development trend of the chemical industry. According to foreign experience, government departments attach great importance to environmental protection, and large-scale capital investment generally occurs in the middle and late stages of modernization. The social and economic development of this link has entered a stable link, and improving the quality of life of residents and the natural environment has become the center of social development.
