On November 9, 2017, the 15th Bus Market Research Conference jointly organized by China Highway Society Bus Branch, China Highway Vehicle Machinery Co., Ltd. and Oukejia (Shanghai) Automotive Electronics Co., Ltd. was held in Guilin, Guangxi.
Wang Qiying, Chairman of the China Highway Society Bus Branch, Xie Guoping, Deputy Director of the Information and Industrial Development Department of the National Information Center, Qi Zhihao, Senior Technical Consultant of the Bus Branch, Wang Jian, Public Transportation Scholar of Chongqing Jiaotong University, and Ou Kejia Okejia (Shanghai) Automobile Zhang Xiaoping, general manager of Electronic Equipment Co., Ltd., and related leaders from the China Highway Society Bus Branch, industry experts, representatives of related bus companies and parts companies, attended the conference, and discussed the changes and development trends and overall situation of the passenger car market in 2017. Analysis and discussion; and the participating experts presented their wonderful insights and speeches at the meeting. This session was presided over by Hu Xuanru, Secretary General of the China Highway Society Bus Branch.
It is reported that this session is mainly about the following aspects:
1. The impact of national policies on the current bus industry and bus market 2. Research on passenger car products, technology and standards development trends 3. Development trend and trend of foreign bus 4. Impact of bus safety standard upgrade on industry development 5. Passenger car intelligence and safety Trends in technology development 6. Current status and development trend of bus market 7. Current status and development trend of new energy bus market 8. Characteristics of passenger car market from January to September 2017 9. Outlook of passenger car market in 2017 and basic judgment in 2018.
Wang Qiying, Chairman of the China Highway Society Bus Branch, said that the Bus Market Research Association of the Bus Branch is one of the annual core meetings of the Society, closely following the national policy orientation, with the theme of promoting the technological progress and market expansion of the bus industry, actively inviting relevant leaders and experts. He has made special reports on industry hotspots. In recent years, he has conducted extensive exchanges on new standards, new energy bus technology, passenger car structure safety, new parts and components application, and passenger car energy-saving technologies, which have promoted the technological progress of the industry and also for passenger cars. Enterprises grasp the market opportunities and avoid market risks, providing an authoritative and professional exchange platform.
Safety and environmental protection are the eternal theme of the passenger car industry. According to the China Bus Network, the bus market research conference was held in Qingdao, Shandong Province from the first bus market research conference. It has been held for 15 sessions as of the meeting. Looking back at the impact and significance of previous sessions, the purpose is to promote the healthy and coordinated development of the bus industry. I wish the China Bus Market Research Association will be better and better in the future!
Elbow in pipe system, elbow is the pipe that changes the direction of pipeline.
Use:A Pipe Fitting used in pipeline installation is used to connect two pipes with the same or different diameters to make the pipe turn at a certain angle and the nominal pressure is 1-1.6Mpa.
Application range: because of good comprehensive performance of the elbow, it is widely used in chemical, construction, water supply, drainage, oil, heavy industry, freezing, health, water heating, fire, electricity, space, shipbuilding and other basic projects.
1, the material can be divided into cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics.
2, the production methods can be divided into push, press, forge, casting and so on.
3, according to its radius of curvature, it can be divided into long radius elbow and short radius elbow.
4, according to the pressure grade, there are about seventeen kinds, and the same as the American tube standards, such as Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; the most commonly used are the two kinds.
5, according to different shapes and uses can be divided into: groove elbow, card type elbow, double bearing elbow, flange elbow, different diameter elbow, bent head, bending head of internal and external teeth, stamping elbow, push bending head, socket elbow, butt elbow, inner wire elbow, etc.
It is required to control the radius of curvature. For example, if the radius is 1.5D, the radius of curvature must be within the required tolerance. Because most of these pipes are used for welding, in order to improve the welding quality, the end is all turned into a slope, a certain angle and a certain edge. This requirement is also strict, the edge is more thick, the angle is more and the deviation range is specified, and the geometric size is much more than the pipe. The surface quality and mechanical properties of elbow are basically the same as those of pipes. For welding convenience, the material of the steel connected to the pipe is the same.
