China Drying Newsletter On February 1st, at the press conference held by the China New Zealand Office, Chen Xiwen, deputy head of the Central Rural Work Leading Group and head of the office, said that in order to interpret the spirit of the Central No. 1 document, he must speed up modern agricultural construction, except In terms of funding, technology, materials and equipment, etc., we must increase our support. It is important to make efforts to innovate the agricultural management system. Industry experts believe that the organization and specialization of the agricultural management system will promote the transformation of products and services by agrichemical companies such as chemical fertilizers, pesticides, and agricultural plastics. On January 31, 2013, the Central Document No. 1 “Some Opinions of the Central Committee of the Communist Party of China and the State Council on Accelerating the Development of Modern Agriculture to Further Strengthen the Vitality of Rural Development†was released, proposing to increase the intensity of rural reforms, policy support, and science and technology drive, focusing on modern Agricultural construction will give full play to the superiority of the basic rural management system and focus on building a new type of agricultural management system that combines intensive, professional, organizational, and socialization. The No. 1 document proposes that efforts should be made to improve farmers' intensive management, vigorously support the development of various forms of new-type farmers' cooperative organizations, and emphasize the need to build new mechanisms for agricultural socialization services and vigorously nurture and develop the main bodies of multi-services. Support farmers' cooperatives, professional service companies, professional technical associations, and agro-industrial enterprises to provide low-cost, convenient and all-round services for agricultural production and operations, give play to the vital role of operational service organizations, and guide operational service organizations to participate in public welfare services. , Vigorously carry out production services such as the prevention and control of pests and diseases, plastic film coverage and recycling; and promote science and technology commissaires in rural science and technology entrepreneurship. Sun Weishan, deputy secretary-general of the China Petroleum and Chemical Industry Federation, expressed that the establishment of a new type of agricultural management system will help the transformation of agro-chemical companies, and is more conducive to the connection between agro-chemical enterprises and farmers. This also requires that agrochemical companies not only produce products, but also guide farmers to use these products, that is, "not only sell products, but also sell technology." However, the current large-scale fertilizer companies mainly produce basic fertilizers, and large-scale promotion of agrochemical services is not realistic, but more targeted fertilizers can be produced by region. The compound fertilizer industry is mostly for small and medium-sized enterprises. It is closer to farmers and markets, and can fully cooperate with local agricultural science and technology departments to deepen soil testing and formula fertilization. Industry insiders suggested that this transformation of agrochemical companies will help solve food safety problems. The pilot project on the use of low-toxic, low-residual pesticides and high-efficiency slow-release fertilizers proposed in the No. 1 document will not only help the agricultural resources industry to develop in a healthy and orderly manner, but also help to further safeguard grain and food safety. Chen Xiwen emphasized that the unreasonable use of pesticides is mostly due to the lack of scientific knowledge among farmers. They should start at the source and educate farmers about science. Sun Weishan stated that the number of agricultural business entities has become smaller and the volume has become larger, which is conducive to the rational use of pesticides and chemical fertilizers together with scientific use, reducing the impact on the environment, and realizing agricultural scientific management from breeding to harvesting.
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.
From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.
However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
