A number of mechanical independent professional brand exhibitions have been established and developed, such as China International Machine Tool Show, China International Mould Technology and Equipment Exhibition, Chongqing Machine Tool Mould Exhibition, Beijing International Technology Exchange Conference, Tianjin Auto Mould Exhibition, Guangzhou Asian Mould Exhibition, Shenzhen The exhibition of mechanical molds, etc., the development of Shanghai convention and exhibition industry is particularly rapid, with more than 500 exhibitions per year, and an exhibition area of ​​more than 7 million square meters, ranking first in cities across the country.
According to Luo Baihui, head of the International Association of Mould & Hardware Plastics Industry Suppliers, since the outbreak of the global financial crisis in 2008, the global exhibition industry has undergone important changes. Affected by the crisis, the scale of European and American mechanical exhibitions declined, and the audience dropped sharply. However, in emerging countries such as China and Brazil, the mechanical exhibitions showed an expansion trend. At the 2010 Shanghai International Machine Tool Show and Guangzhou Asian Model Exhibition, the world-renowned manufacturers participated. The number and new technologies and new products have reached new heights, attracting global attention. By 2015, the output value of China's exhibition industry will increase from 145.3 billion yuan in 2010 to 300 billion yuan.
The "12th Five-Year Plan" of the exhibition industry ushered in the era of "Hundred Flowers Blossom"
Luo Baihui, head of the International Association of Mould & Hardware Plastics Industry Suppliers, said that in the next five years, China's convention and exhibition industry will enter the fast lane of development. In recent years, the metal mold industry has awakened its brand awareness. The exhibition is a good platform for displaying brands. The coastal cities of Shenzhen, Guangzhou, Shanghai, Ningbo and other places have always been the focus of exhibitions. Now, with the expansion of domestic demand, second-tier cities have begun to develop. . It is estimated that by 2015, the number of national exhibitions will increase from 5040 to 7000 in 2010, and the exhibition area will increase from 50.5 million square meters to 100 million square meters. The output value of the exhibition industry will increase from 145.3 billion yuan to 300 billion yuan.
Carbon steel flange is an indispensable part of pipeline connection, which is made of high-quality carbon steel through various processes. JIS BS DIN ANSI Italian standard. Flange standards are commonly used, PN10, PN16, 10kgs, 16kgs, ANSI150LBS, 300LBS pressure carbon steel Flanges are the most conventional, popular and commonly used flanges. Carbon steel flanges are divided into three types: forging, steel plate, and casting. Among them, carbon steel casting flanges have low cost, mechanical properties, material properties, and impact resistance, which are in line with the connection of low-pressure pipelines. Pipe connections in sparsely populated areas, widely used in the Middle East and Russia.
The biggest use of carbon steel flanges is as a method of connecting pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
When using, evenly weld the flange with the pipeline, and then fasten the connection with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.
It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
Types of carbon steel flanges:
According to the shape can be divided into: FF, RF, BLIND, SLIP-ON, Welding Neck
, Threaded , Socket Weld
According to the pressure can be divided into: PN10, PN16, PN25, PN40, PN63, PN100,
15OLBS.300LBS
According to the process, it can be divided into: forging flange, precision casting flange, steel plate flange
According to the material can be divided into: ANSI A105, SS400, CT20, Q235, 16Mn, 20Mn, ST37.2
