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 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;
How to make the ventilation duct more effective
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 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.
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.
