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.

Ministry of Agriculture: Gradually establishing a long-term mechanism for subsidies for rice lateral deep fertilization
[ China Agricultural Machinery Industry News ] On September 15, the Ministry of Agriculture officially issued a reply to the No. 1893 proposal of the Fifth Session of the 12th National People's Congress (the Agricultural Office (2017) No. 304). The Ministry of Agriculture proposed to the representative of Tan Zhijuan that the agricultural machinery and equipment that play a key role in the “three reductions†of the rice side deep fertilization device should be included in the scope of agricultural machinery purchase subsidies. After consultation with the Ministry of Finance, the reply is as follows:
Ministry of Agriculture: Gradually establish a long-term mechanism for subsidies for rice deep-fertilization devices/pictures from Baidu invasion
Since 2015, some farms in the Heilongjiang Reclamation Area have carried out experimental demonstrations of deep lateral fertilization techniques for rice, and have achieved certain results. Compared with traditional rice fertilization technology, rice lateral deep fertilization technology has the advantages of fertilizer saving, labor saving, time saving, fertilizer saving, lowering cost, improving fertilizer utilization rate and reducing water pollution. Since 2016, the Heilongjiang Provincial Agricultural Reclamation Bureau has subsidized the purchase of rice side deep fertilization equipment by using new agricultural machinery subsidy funds.
In recent years, the Ministry of Agriculture and the Ministry of Finance have fully played the guiding role of the agricultural machinery purchase subsidy policy, and actively promoted the application of water-saving, medicine-saving, fertilizer-saving and other "one control, two reduction and three basic" effects of obvious machinery, fertilizer machine, fertilizer machine Machine tools such as manure spreaders and fertilizers are included in the scope of subsidies. In 2017, the General Office of the Ministry of Agriculture and the General Office of the Ministry of Finance jointly issued the “Notice on Launching the Pilot Work for the Purchase of Agricultural Machinery New Products in 2017†(Nongjian Cai [2017] No. 39), with the structural reform of agricultural supply side and the green development of agriculture. Guided to guide the relevant provinces to take into account the current situation of China's agricultural machinery product innovation and the needs of the agricultural industry in the province, and the agricultural machinery that is required for the application of green yield increase technology, such as the rice side deep fertilization transplanter, which does not have the qualification for agricultural machinery purchase subsidy. Innovative products explore the pilot of purchase subsidies.
In the next step, the Ministry of Agriculture and the Ministry of Finance will increase support for the promotion and application of rice-side deep fertilization devices. First, encourage and support the Heilongjiang Provincial Agricultural Reclamation Bureau to continue to subsidize the rice side deep fertilization plant. The second is to guide the relevant provinces to use the agricultural machinery new product purchase subsidy pilot, explore and improve the operation method of subsidies for the rice side deep fertilization device, and gradually establish a long-term mechanism for subsidies for the rice side deep fertilization device. The third is to strengthen the pilot tracking assessment, and carry out the agricultural machinery promotion and appraisal for the qualified rice side deep fertilization device, and incorporate the device into the agricultural machinery purchase subsidy as soon as possible.
