Project Name: Nigeria long (Jiangsu) 5 tons / year high-grade carbon black production line project of carbon black Co. Ltd.
Project time: September 2014
Project location: Xuzhou, China
Nigeria long (Jiangsu) carbon black Co., Ltd was founded in June 2013, is located in the Jiangsu Province Xuzhou Pizhou Economic Development Zone, the factory covers an area of 6.25 million square meters, with a total investment of 2.6 billion yuan RMB. Japan's Nippon Carbon Co., Ltd. is a smaller carbon black enterprises, factory located in Tahara, Aichi Prefecture, Japan, with an annual output capacity of 7.3 million tons.
Nigeria long carbon black project is Zhongxiang group carbon black industry research and Design Institute of EPC general contracting project, is so far the Academy of carbon black has so far signed the largest carbon black engineering general contracting projects. The carbon black was put into operation in October 2015.
Set up by the Japanese Nippon Carbon Co., Ltd. in China owned Enterprises -- Nigeria long (Jiangsu) carbon black company with an annual output of 5 million tons of rubber with carbon black production device, after more than two years of construction, in September of this year into the commissioning phase. In September 4th, the first carbon black production line ignition, in September 21st the last line of the production of feed, the process has achieved a one-time success through, so far, the production line running normally.
The carbon black project from the main device to the back of the tail gas power generation project using a total of Wuxi Kyle grams control valve of a total of more than 100 units, of which 40 sets of low load valve, 10 high-temperature butterfly valve, high performance butterfly valve 12, the remaining are globe valve. The number of valves by Nippon Steel experts, design expert Zhongxiang group carbon black school owners and strict supervision, all the valves are in line with the owners of the requirements.
For this part of the butterfly valve, as long as people read the mechanics of materials and professional heat treatment of metal materials all know: metal materials at high temperature (C), can be carburizing or nitriding (N2), is because of this reason, valve stem, the sleeve is in the carbon black industry went into the stem and carbon black at high temperature the sleeve, so that the valve stem and sleeve of the carbon black mutual penetration, so that the 2 parts like welding as tightly bonded together, like others said cars were unable to stem is pulled out from the sleeve, we take the first 3 days of the stem 17-4PH nitride, and chrome plated, so not infiltrated in high temperature carbon black the lower stem, the stem that is never going to be stuck and corrosion of carbon black. In addition, you can also use the structure of the external bearing, for the high temperature or impurities more media, bearing external can effectively prevent the valve blocking.
Requirements for the control of travel time: the selection of the control valve actuator should be able to face full valve stroke and process on the level of the amount of leakage requirements. In some occasions, such as the selection pressure control valve (including vent valve), should consider the actual pressure difference of appropriate amplification, which requires the implementing agencies to provide a larger force. Otherwise, it may be when the abnormal situation occurs, the actual pressure before and after the valve is relatively large, it will not be closed or open the risk of.

Otherwise, it may be when the abnormal situation occurs, the actual pressure before and after the valve is relatively large, it will not be closed or open the risk of.
The valve has been put into use and operation of the good and for Wuxi Kyle grams for, can be described as a landmark project, not only quality products has been recognized by foreign experts, and carbon black industry also began with the results.
