[Ten years of development of chemical equipment] 1055-2017 The development and application of high-pressure orbital ball valves for hydrocracking units passed the appraisal
Thread Content
Chemical science and technology has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. It is more lively and more exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss. Pay attention to fire prevention in July. ---------------------------------- On August 15, 2017, the scientific and technological achievements of "Development and Application of High-Pressure Orbital Ball Valve for Hydrocracking Units" passed the technical appraisal organized by Sinopec Equipment Department. The project is jointly undertaken by Guangzhou Petrochemical, Sinopec Engineering Construction Co., Ltd., Sinopec Luoyang Engineering Co., Ltd., Shanghai Kaiweixi Valve Co., Ltd. and Hefei General Technology Research Institute. It is a major equipment localization project of Sinopec. The project developed a new structure of high-pressure hydrogenation orbital ball valve, which adopts a guide structure design that can maintain the valve stem online, which effectively improves the reliability and service life of the valve. It also simulated actual working conditions and conducted 100 tests of the full pressure difference switch. The developed orbital ball valve was put into use in February 2015 on the new hydrogen compressor C9102A three-stage outlet pipeline of Guangzhou Petrochemical's 2 million tons/year diesel hydrogenation reforming unit. It has been running smoothly and reliably, fully meeting the process production requirements. After listening to the report and reviewing relevant materials, the experts of the appraisal committee unanimously agreed that the project passed the achievement appraisal. The expert group believes that the overall technology of the NPS8class1500 hydrogenation high-pressure orbital ball valve developed by the project has reached the international advanced level and can replace imports, and it is recommended to promote its application.

On June 28, 2021, Shanghai Kaiweixi held a factory joint acceptance meeting for the high-pressure large-diameter orbital ball valve (NPS 16 Class 1500) for the Zhenhai Refining and Chemical 4 million tons/year hydrocracking unit in Shanghai. The experts in the acceptance group are composed of experts from Sinopec Zhenhai Refining and Chemical Branch, Sinopec Luoyang Engineering Co., Ltd., and Sinopec Nanjing Valve Supply and Reserve Center. At the meeting, experts from the acceptance team listened to the development summary report of Shanghai Kaiweixi and the introduction of Shanghai Zhongshen's manufacturing supervision. They inspected the manufacturing site, witnessed the product's shell strength test, high-pressure gas seal test, low-pressure gas seal test and dispersion test, and reviewed documents related to design, manufacturing, testing and inspection. The acceptance team believes that the developed NPS16 Class 1500 high-pressure large-diameter hydrogenation orbital ball valve meets the requirements of the "Technical Annex for Orbital Ball Valve for Zhenhai Refinery's 4 Million Ton/Year Hydrocracking Unit", and the acceptance team unanimously agreed to pass the acceptance. As of May 2021, Shanghai Kaiweixi has experience in the design, manufacturing and application of more than 2,000 hydrogenation orbital ball valves, and will continue to provide high-quality orbital ball valves for hydrogenation devices.
From July 6 to July 7, 2023, the two product scientific and technological achievements appraisal meeting of the NPS16 Class1500 high-pressure large-diameter hydrogenation orbital ball valve & ethylene unit cracking furnace 750°C high-temperature ball valve developed by Shanghai Kaiweixi Valve Co., Ltd. was held in Yancheng, Jiangsu. The appraisal meeting was organized by the China General Machinery Industry Association. The appraisal expert group was composed of nine experts from Hefei General Machinery Research Institute Co., Ltd., School of Petrochemical Engineering of Lanzhou University of Technology, Sinopec Guangzhou Engineering Co., Ltd., Sinopec Engineering Construction Co., Ltd., Sinopec Shanghai Engineering Co., Ltd. and Wison Engineering Co., Ltd. Representatives from Sinopec Materials and Equipment Department, Sinopec Guangzhou (Luoyang) Engineering Co., Ltd., Sinopec Tianjin Branch, Sinopec Shanghai Branch, Sinopec Hunan Petrochemical Co., Ltd., Sinopec Qilu Branch, Zibo Xintai Petrochemical Co., Ltd., Zhejiang Yuanjin New Materials Co., Ltd., Zhenghe Group Co., Ltd., Shandong Huifeng Petrochemical Group Co., Ltd. and other units attended the meeting. * meeting.
At the meeting, experts and representatives of the appraisal committee inspected the prototype and production test sites, witnessed some performance tests of the product prototype, listened to the development summary report made by the development unit, and reviewed relevant documents and information on design, manufacturing, testing, inspection, and quality assurance. After inquiry and discussion, the two products developed, NPS16 Class1500 high-pressure large-diameter hydrogenation orbital ball valve and ethylene unit cracking furnace 750°C high-temperature ball valve, have independent intellectual property rights. Their main performance indicators have reached the advanced level of similar international products. It is recommended to further promote and apply them. Picture As of July 2023, Shanghai Kaiweixi has experience in the design, manufacturing and application of more than 2,600 hydrogenation orbital ball valves, and will continue to provide high-quality orbital ball valves for hydrogenation devices. It has the batch supply performance of more than 1,700 sets of 750℃ high temperature ball valves for cracking furnaces of ethylene plants, and will be further promoted and applied.
